Step out of your trailer to be in the shade and feel the cool air, protected by a screen that frames a view of the lush landscape beyond. This experience was the inspiration behind BENT Annexe small home addition, an attachment for a charming family of four and their two lovely sausage dogs. Because every day should be like a breeze of fresh air, surrounded by nature.

BENT Annexe is an additional space to a charming 1960s house that reconnects it to the garden. In contrast to the weight and introspective nature of the original home, this new, light and light-filled annex opens and faces outwards, looking more like a sheltered garden spot than a traditional living space.

Carefully removing what customers no longer needed, leaving only the generous rooms of the existing home, an excellent foundation remained to begin with. The small home addition fits perfectly under existing eaves, with new spaces around the original house, joined by a continuous cover line that folds above.

The original rooms in the house have been restored and revitalized to house bedrooms, while a separate living area in the front room benefits from existing corner windows and a fireplace. New living areas embrace the exterior, giving the impression of a garden that migrates in. East and west brick walls protect open spaces from prying neighbors and focus attention on the garden.

The trick to making the annex look like a part of the garden was to create green spaces on both sides, separating the small home addition of the original home through a patio. Of course, the central courtyard improves cross-ventilation and allows northern light to enter the master bedroom, but with full-height windows on either side of the living room also creates the illusion of continuous space, confusing the boundary between the inner side and the outer side.

A brick base in the living room - at the right time to sit - extends into the garden. Brick paving also crosses the boundary between interior and exterior, further confusing this boundary. There is a window seat that exits the dining room to bring light from the kitchen and dining room, as well as backyard views. Windows open to the backyard and this special seat is bathed in golden light from the north, making it the perfect place to sit with a cup of tea and a book.

The small home addition projects to an outdoor deck dining area, protected by a retractable shading device.With a circular pool within walking distance, this is the perfect place for entertaining and long outdoor summer evenings. The house presents passive strategies to reduce the need for heating and cooling. Tall windows in the living area capture views of the sky and let the northern light seep into the house, warming the concrete floors passively. Meanwhile, the movable window flaps can be opened to allow air in for passive cooling. BENT Annexe small home addition fills the need for additional space, but it also creates a garden-like home by drawing adults, children, and dogs out into the yard.

The new house for a large family is located on the same property as the owner's old house. The two residences are in a parallel orientation and are separated by a swimming pool, which exists as part of the original residential program. This common area also connects and at the same time contributes to the visual division between the two residences.

This reduces program congestion and allows family members to see and interact with each other. Surrounded by the green of the trees and the garden, the space covers the exterior in all directions except west - facing a wall.

The location of bathrooms and storage rooms help filter out the afternoon heat. We opted for the apparent concrete to convey the owners' taste and preference for smoothness and simplicity. Black aluminum panels surround the outside wall to maximize privacy while natural light and wind are present inside the house.

Photographs Paulina Ojeda

The Ceiba Residence was created from a small and old neocolonial building of the 1930s, in which the current owner lived for over 10 years, until suddenly the need arose to extend it to house his new family: he , visual artist, a dancer / yoga teacher, and two small children. Although the original residence had the typical elements of Mexican neo-colonial architecture, it had no great historical or architectural value, but the design guideline was to preserve it intact. Just like the old pyramids, where the new structure was built on top of the old one, leaving it trapped inside, a respectful wrapper was designed.

The home addition houses and delicately displays the original shapes, elements and materials. Each of the constructive stages is clearly established. The home addition program proposed the construction of a yoga room that could be accessed without entering the house, two new children's dormitories, and expanded kitchen, dining and service areas.

The building is accessed through a very small hall, in front of which was the original façade of the house and the door to access private areas or, from that same lobby, on the right, a spiral staircase next to the trunk of a ceiling. it lifts the user to the top of the tree and from there, deviating from the highest branches, suddenly appears a pond, a garden and the yoga studio. Continuing in the small hall and crossing the old main door you can access an environment that leads to a private courtyard around which the house develops. Large glass cloths allow a large tree, a waterfall, and the corridor's three-point arch to be the set design and witness to all the family's activities.

The intimate area of ​​the house is accessed through a side door in the courtyard, located next to the water tank that resembles the ancient Muslim cisterns and emits a calm and continuous murmur of running water. Thick 4 meter high adobe walls house a library / music room, bedrooms and bathrooms.

At the rear of the courtyard, retaining its original location and behind an ornate archway, is the dining room and kitchen with an open view of the main courtyard. Crossing a narrow side corridor to the kitchen is a second courtyard, larger than the first and covered by a huge old sapod tree, under which the artist's studio sits.

The Ceiba Residence is far from the great pretensions and formal exaggerations of some architects, its simple façade and refined interior design, full of symbolism, vegetation and intimate spaces based on the words of Luis Barragán, who warned that they were being forgotten by the architects: beauty, inspiration, charm, magic, spell, enchantment, serenity, silence, intimacy and surprise.

Victorian House Addition, Melbourne, Australia

Design bagnoli
Area 180 m²

This renovation and addition transforms a Victorian house into a well-lit residence for the client. Distinct connections, materials, and shapes organize the elements of the house, while dissolving the exterior of the enclosed volume.

Designed to use noble materials and shapes, highlighting existing typologies, this project has developed from a core concept of element separation. The original 1887 Victorian house was an important design element to be incorporated into the new home. Keeping as much of the old building as possible was important as a way of preserving the history of that place.

The upper deck is designed to float over the old house. Glazed paths internally and externally protected with regularly spaced vertical wooden elements help the idea of ​​a volume that dilutes and gives lightness to the shape. The cladding and a large pre-existing tree also act as shading devices and create shading patterns from the natural light that enters the house as the sun moves during the day. A large spiral staircase distinctly separates the new upstairs bedroom and bathroom spaces from the living area.

The back of the house faces a nature reserve. A mirrored fence was designed allowing for a more active and interactive façade between the house and the reserve. The mirrored surface visually enlarges the reserve and provides a playful resource for residents to enjoy. Appropriating the existing collective context in this field was extremely important for the development of this project. Given the limited space available for the new home addition, the project needed to be compact and efficient, with no "wasted" spaces.

The house offers "little shrines" so that people can be together as well as have their privacy. The family has appropriated the paths within the house, and they like to discover new ways of seeing space as light and seasons change and react to wood and bronze. Each space is designed for the inhabitants, including, for example, the base of the stairs that also functions as a shoe exchange seat and shoe rack.

Most of the house remained friendly to its surroundings of Victorian houses. The dissolving nature of the wooden spaced facade and roof shape offer a sympathetic response to existing neighborhood conditions. At the back, the staggered, diamond-shaped fence allows the adjoining park to enter the garden, while the mirrored side of the park visually extends the open space below the floating upper floor of the house.

A showcase home for the family, among the needs presented, included the Oreo, the family dog, who needed to have space in the yard not to run around the house. The family also asked for the house to be fluid, larger as it had the most reserved private areas. Customers wanted the house to have moments of joy, which was achieved through materials and light interactions, both inside the house and with the neighboring park. Oreo has passage under the glass floor along the side of the house - allowing it to run freely from the front to the backyard.

Vilarinha Concrete Home Addition, Porto, Portugal

Project  Vilarinha House Addition
Design Luís Peixoto
Location Porto, Portugal
Area 180 sqm

The project was born from the need to rehabilitate a semi-detached house, integrated in an economic district built in the second half of the 1950s. Its location near a large urban park has made it attractive to younger families. However, due to the small size and large compartmentalization of the interior of the house, an intervention was required at the level of the increase of the areas and the modernization of the space with regard to their use.

The expansion of the living space with the concrete home addition was then thought through the redefinition of the existing housing compartments and the use of the exterior space of the lot, with the construction of an autonomous volume, which assumes itself as a new archetype, different from the economic house of the 1950s.

Functionally, the space of the rooms remains in the existing house, while the new concrete home addition receives the social spaces. The project strategy was based on this separation between the two constructions, emphasized in the language and materiality that the new volume assumes, in a clear allusion to the work of Mies van der Rohe. This lightweight and transparent construction stands as a counterpoint to the compact volume of stone and roof base. Together, one archetype does not annul the other, and complement each other and value their identity by corresponding to the different ages of the neighborhood. The point of mediation and connection between the two distinct moments of the house corresponds to the entrance door, where we arrive and depart.

The Loft House Addition is a contemporary annex to an existing villa. Previous public areas were tight and dark, unsuitable for a growing family. With a clean, minimalist palette, the new addition creates a larger house with three bedrooms, two bathrooms, a spacious office and several garden areas.

Strategically positioned windows open the house addition to the patio and garden. In the living area, the glass forms an elegant separation between the ceiling planes and the interior walls, creating a feeling of lightness and space. The refined material and color palette make a subtle reference to the heritage origins of the house while maintaining a clean and minimalist interior.

The internal masonry walls are painted white, in continuity with the monochrome color palette, and resemble the brick walls of traditional houses. In the bathroom, the white tile texture resembles brick again, contributing to a contemporary view of traditional materials.

Project Grid House Addition
Design Warc Studio Architects
Location  Camberwell, Australia

This project is for modest but highly detailed changes and home additions to a residence in Camberwell, Victoria. In addition to the proposed extensions, the briefing provided for the modernization of existing toilets, wardrobes, improved internal circulation, the provision of a swimming pool, and utility areas.

The project solution focuses on interacting with the garden and outdoor space while focusing on environmental comfort. Windows, cabinets, walls, and ceilings have also been strategically placed to reveal views and openings to the outside. Upon entering the house, the main hallway provides an immediate view of the back garden.

As users advance, a range of views develops: the northern garden framed by cupboards, glimpses of the sky through a skylight, tree views through tall windows, and views of the outdoor areas. Later attachments are surrounded by hardwood grids that mitigate sunlight from the north and west, maintaining views and visual surveillance of the pool area.

The louvers in this small home addition can be opened to maximize the afternoon sun during the winter and allow the façade to be maintained.


Multiple sustainable features were used in this project and include: high levels of insulation, double glazing, externally operable screen to maximize seasonal variation in passive solar radiation, local and sustainable Victorian wood plywood utilizing yield-maximizing profiles. In addition there are low VOC finishes, formaldehyde free plywood, rainwater collection, hydronic heating, compost and vegetable garden.

Design Plan21
Location Aira, Japan
Project Year 2016
Photographs Akira Ueda

This project is a couple of structures where the main house and the guest house addition face each other along a watercourse. The main house was first built and, five years later, the guest hous additione is conceived as an extension.

The place is located in Aira city, southern Japan, in Kagoshima prefecture.

Originally the Japanese houses were open. However, in recent years, housing in Japan has changed a lot and is closing. In response to this situation, this small home addition was designed to restore its original form of liberating housing. In extending the guest house, the architect reuses the two space elements that the old Japanese houses had. They are the space under the eaves and the dirt floor. The interior floor of the guest house addition is finished with an adobe floor that extends from the inside to the outside, with the outside covered by large eaves. In addition there is a courtyard with plants.

In recent years, many Japanese houses have abandoned their space elements, disconnecting from the outside. As a result, many of them have lost touch with nature. In this house addition, the architect connects interior and exterior with the adobe floor, create large eaves and realize a life integrated with the landscape.

When Tom and Meeghan McInerney bought a 1940s house on Lake Wendouree, it was, despite its age, a dream come true for any architect. Formerly owned by two sisters who lived there for 60 years, the property had been extremely well maintained, coming to with a maintenance log that detailed services such as a semi-annual refinish.

The original wood panels and the ornate plaster ceiling were also in good condition. However, the couple were eager to create a light and modern space in their new home, and Ballarat architect Nathan Porter shared this vision. "It was very dark and undervalued (and) one of the things Meeghan and Tom wanted to do from an early age was to see naturally lit spaces as soon as you enter the house," says Nathan. “We kept as many original elements as possible, but there were some areas in the back that needed a good makeover.”

The plan was to create two architecturally delineated zones, the original front with bedrooms, bathrooms and an office, leading to a naturally lit contemporary home addition. Existing wood floors that were in perfect condition at the front of the home addition were combined with recycled floorboards at the back extension, creating a conductive wire that works for both areas and unifies the new and old.

The rooms have become contemporary suites, with contemporary fixtures like black faucets and classic tiles provided by the couple. Large windows overlook the north-facing backyard, a larger space where the family has spent a lot of time since moving in late March this year. "What we found when we put the glass was that the house opened to all the other beautiful details of the town houses," says Nathan.

 A small courtyard created by two small areas gives a view of the backyard and allows Tom and Meeghan to supervise their young daughters without suffocating them. Wood panels break the length of masonry on the façade, while the 1940s bricks were reused in a contemporary pattern to continue the union of old and new. Meghan's favorite aspect of the renovation, however, is the naturally light-filled kitchen. "It's a beautiful kitchen to work with," she says. “I just love the way we're living in the house. It's just as we imagine having the kids playing here, and we've had some nice dinners.” She looks at Nathan, who shakes his head and says, “It's probably exceeded our expectations. "

The DLC House Addition is located in a village on the south coast of Madeira Island. The traditional Madeiran house, built in basalt stone, with tile roofing and square layout. The back of the house is buried, as is common in Madeira, due to the sloping topography of the island. The main house is around 80 years old, where small outbuildings were built over time.

The house was no longer fit for the family, and architect's task was to design a small home addition and rearrange the interior of the house, keeping as much as possible the existing one. The south-east sea view, the sun exposure, the existing structure and the minimum distances to be respected in relation to the property limits defined the implementation of the new home addition construction almost immediately.

One of the main ideas of the project was to create a patio at the back of the house to create diverse views and outdoor spaces. Although this space does not offer the sea view from the front of the house, it has a lot of use on windy days. The new small home addition contains the living and dining area, the transition annex, probably from the 80's, contains the kitchen and a small bathroom. In the old part of the house there are the two bedrooms, a new bathroom and a storage space. The house addition does not imitate the traditional Madeiran style, but has its own identity, clearly visible through the contemporary choice of materials and construction system: the structure in the LSF (Light Steel Framing) system, lined with corkboard boards and wood planks.

Black Box II Home Addition is the latest in a series of small home additions that affect existing architecture in a unique way. Conceived as a jewelry box, the large openings blur the inner / outer boundary, revealing the marking work within the use of complementary materials.

The Black Box II Home Addition is covered with large fiber cement plates with a perforated pattern. In contrast, wood, porcelain and ceramics illuminate the interior. Large windows incorporated the garden into the house, the interior and exterior materials interact to connect the spaces.

Inside, oak wood paneling covers the walls and roof of the shed, while a red cedar mesh lines the exterior volume. The slate slabs on the terrace are adjacent to the concrete kitchen floor. Heritage of the past, the original oak wood floor of the dining room, preserved and restored, gives the project a special tone. The kitchen island, made of solid oak, stands monumentally in the center and serves as an altar for daily rituals. On the perimeter, most superbly, is white and black furniture, as well as cabinets.

This home addition project is an appeal to the constructive art, recognizing the complicity between the architect, the builders and the owners, all actively involved in the pursuit of quality, both technical and aesthetic. The art of architecture manifests itself here in all its dimensions. This semi-detached townhouse, made of red clay bricks, is typical of Westmount and the Notre-Dame-de-Grâce municipality of Montreal. Through the reconfiguration of outdated internal divisions and the grafting of two black volumes in juxtaposition, pre-existing architecture is enhanced and transformed to better reflect the modern lifestyle and aspirations of its inhabitants. Architects are always striving to find the right balance between the old and the new in order to create a coherent whole while preserving the authenticity of existing details while affirming the contemporaneity of interventions.

Renovating this Tudor-style residence in Rye, New York, connects the house to the exterior, adding a lighted program and circulation. By maximizing habitable land use, the home addition also responds to the key parameters of the existing home, preserving its character and history within the context of the suburban neighborhood.

In addition to the restoration of original stucco and wood façade, the architects have added a new wooden entrance that offers a delicate and discreet contrast with the neighborhood street. This new material appears again as the lining for the most minimalist and abstract attachment extending from the back of the house.

Its simple rectangular shape contrasts and complements the original Tudor structure of columns and beams. This small home addition is surrounded by a dark, charcoal-stained cedar skin, mimicking the colors found on the existing façade. The perceptive effect of the oscillations between the outer monolithic form and the wood as an abstract striation allows the attachment to gain a movement that transitions between the old and the new.

The glass staircase built between the existing house and the home addition creates a "blank space", allowing natural light to enter the surroundings around this vertical circulation. The new wooden, steel and glass staircase hung in the fireplace of the existing home, creating a sectional void, providing moments of visual and spatial connectivity within and beyond the landscape. Through a series of elegant disjunctions between light and space, the project is unified into a symbiotic relationship between old and new.

The wooden home addition adjacent to a brick house creates a new relationship with its green surroundings. The project consists of a major interior transformation with a new project and wooden home addition on the back of the original brick house.

The original brick house was rebuilt after the war, including a sloping roof and ceramic tiles. Large trees are arranged at the rear of the land creating a charming landscape around the house. The new wooden home addition opens the original brick home to this scenario, creating a new look. Natural materials are used that relate to the surroundings, maintaining a clear contrast between existing and newly developed parts.

Downstairs, the home addition provides additional space for a new lobby, which opens onto the street through large windows, and a wine cellar. Outside, the storage room has a more closed-looking wooden facade. Three new residential programs appear at the back of the house (kitchen, bedroom and studio), which are stacked and connected by a new staircase. This vertical grouping results in a vertical extension at the rear, creating a new dialog with the existing one. New dorms in this part of the extension have floor-to-ceiling windows with garden views. The bedroom on the first floor stands out more from the garden, the studio on the second floor is placed behind the high volume of the stairs. This segmentation breaks the high volume of the new wooden home addition and makes the spaces distinct on the outside.

This project is a renovation and extension of an 1880 Victorian brick house in a former suburb of Melbourne, Australia. The new home addition at the back of the house has a kitchen, living room and dining room with large glass doors on the balcony, as well as other utility environments. The predominant materials used are white bricks, which remain internally in the chimney that reflects the outside, as well as a cedar wood gallery and hardwood floor. The exterior forms of the roof dominate the interior spaces and include windows in the openings, dialoguing with the surrounding buildings.

The interiors are largely calmer, made with a white palette, highlighted by light gray concrete, woods and a mirror. Hanging lighting fixtures also make up the set. The old front of the house has also been completely renovated and updated, including new bathrooms and side windows.

Some of the old fruit trees have been preserved and landscaped around with grass to adapt to the new backyard design. The exterior bricks used were white in color to match the existing house painted white and keep the new design light and clean, contrasting with the green grass.

"The old meets the new" noa* (network of architecture) completed an urban residential home and added a contemporary volume. "(...) the material interaction between the old and the new creates a field of confrontation of the generations - a wild impulse for transformation."

In the Bolzano vineyard region, a residence is enlarged; The existing traditional volume is increased through an open and modern home addition. The land, which is protected, is in an urban transition zone between the development of construction on the outskirts of the city and the densest development in the Griesplatz area.

The house is divided into two apartments, which are accessed by an exterior staircase from the courtyard. The new volumes look out in all directions at the idyllic vineyards and the "Guntschnaberg" feature in the west.

The goal was to respect the proportions of the historic building. Therefore, the Villa with a gabled roof and the classic window openings were enlarged with a compact volume, coherent windows and generous openings. The apartments are organized so that the most intimate spaces are in the historical part of the house, while the collective spaces are in the modern part, with views to the south and west.
The diverse formal language of the two parts of the building creates a tension that is exalted by the finishing of the facade: the historical part, white by the plaster, and the home addition with a dark red plaster. Coloring the same plaster rather than a layer of paint on top creates a stoic depth. The two outer staircases on the north and south facades are of darkened natural steel and appear as sculptural bridges. The large square openings have shadow textile elements that create a diffuse haze.

The old house located at the top of the plot lacked natural lighting and ventilation. The biggest attraction of the place was the large amount of vegetation that existed in the front yard, created spontaneously and without maintenance, in addition to existing trees over 25 years old. The main objective of this project was to integrate the existing landscape with the project of a new house addition requested by the client, keeping the notorious garden and existing trees as much as possible.

In the first phase of the project, which included parking and the engine room, many trees were transplanted from the ground. After moving the plants and land from the ground, it was possible to build the walls and lower structure. The second part of the project constitutes the house itself. To allow the vegetation around the house, a service yard serves as a source of light and ventilation.

Another important detail was the incorporation of another natural element such as water. A water recirculation structure was installed with access to the house to distribute and separate the spaces. A water mirror outside filters the water before it returns to the water wall in the lobby.

The new house addition has a master bedroom, a guest bedroom and a studio that can be used as an extra bedroom. The social area is an open plan with operable windows to extend to the courtyards and to allow wind circulation. The double height ceiling of the room houses a reading space on the second floor whose surface is transparent to allow ample space from the social area. The railings are also made of glass to allow the observation of the garden extended from the outside.

The lighting of the house is partially generated by solar panels. Due to the city's location, and natural light is an element that can be enjoyed all year round. The parking lot and engine room are protected by a vegetation cover that extends to the courtyard and maintains the temperature naturally. The living room extends to the front patio with a wooden platform over a metal structure, which allowed one of the oldest trees on the ground to continue growing.

Architects designed a home addition of two floors covered in traditional Japanese Shou Sugi Ban wood, linking the best implementation in the field. Its natural textures also prevail in the remodeling of interior spaces. The new home addition, adjacent to an enlarged kitchen, contains a living room and a staircase leading to the upstairs guest dormitory.

The original house was built in 1999 and designed by Min | Day at Design Architect and Burks Toma Architetcs. In 2005, Min | Day added the pool and the outdoor spaces. Schwartz and Architecture began work on the home addition and interior remodeling in 2009, to be finalized in 2015.

A new single family house designed next to the Oppenheim European office. This contemporary structure is juxtaposed with the adaptive reuse of the historic country house, which became the office. The new and the old share common material and color characteristics.

The Kirchplatz residence is arranged on two floors above ground and one underground with a terrace leading to ground level.

The design of the project born of a contest held by the city of Muttenz was based on the renovation of a historic country house in the central core of the city. The new office addition to house project aims to provide an interpretation and amplification of the existing traditional features of the historic building, originally built in 1743, and its interiors. This is done by having strategic openings for natural light to enter through the thick stone walls and by juxtaposing a white interior finish that contrasts with the texture of wood and stone. Volumetrically the spaces open, overlap and merge.

Sustainability considerations include maintaining an energy-efficient building using MINERGIE (energy efficiency): building standards, roof solar panels, a sustainable choice of materials such as reclaimed wood used for the facade and restoration of architectural elements. where possible.
