Istituto Marangoni Paris

Istituto Marangoni, the celebrated Italian fashion and design school, has a new campus in the 16th arrondissement of Paris.

The project involved the adaptive transformation of a 19th century building and the addition of a contemporary extension. This resulted in the construction of 1,500 square metres of new classrooms, auditoriums, meeting rooms, and office space, spanning five storeys.

Mole Architects elevates “mundane” 1960s English bungalow with new extension

Cambridge-based architectural studio Mole Architects has completed the upgrade and extension of an everyday 1960s holiday home in Aldeburgh, a town on England’s Suffolk coast. The bungalow is just a stone's throw from the sea, hence the project’s title: Stone’s Throw. The home’s existing layout was poorly arranged, its sunny side dominated by a double garage and the living space deprived of adequate sunlight. The reconfigured arrangement now incorporates a bright and airy space that looks towards the sea, elevating a somewhat “mundane” dwelling by adding contemporary flair. Mole Architects Nick Guttridge Nick Guttridge The new extension’s high ceiling includes a triangula... More

New Quebec library by ACDF Architecture is an exercise in thoughtful adaptive reuse

Canadian architectural firm ACDF Architecture has completed the new Bibliothèque T-A-St-Germain in Saint-Hyacinthe, a city in south-western Quebec.

Terzetto by ConForm emphasizes materiality and craftsmanship

London-based architecture practice ConForm has created a contemporary haven filled with texture in London’s West Hampstead. A garden apartment in a four-story mansion block, the home had an awkward layout, low ceilings, poor access to the rear garden, and very little natural light. The redesign undertaken by ConForm capitalized on extending into the rear garden, creating a light and airy, calm and uncluttered space, one that emphasizes materiality and craftsmanship. James Retief James Retief The concept for the rear extension draws on the building’s front facade, where classically designed bay windows and ornate details are typical of Victorian terraces. “The extension is developed as a contemporary cant...

House with pink windows

We were commissioned by our clients to transform an outdated Flemish 3-fronted house with traditional rear extension into a contemporary home with plenty of light. The new home had to feel especially spacious and, above all, take advantage of the view to the green area behind.  Ypsilon Business Photography Ypsilon Business Photography In the design, we kept the main house and replaced the rear extension. The newly added volume follows the same movement as the original side façade and juts out slightly each time. This gives the gabarit four bays, the last of which is inverted and opens up to the surroundings.  Ypsilon Business Photography Ypsilon Business Photography The ground floor received a home off...

Wanstead

  Rees Architects designed the extension and refurbishment to this Victorian terrace house in Wanstead, London. We were also responsible for planning, building regulations, and bespoke joinery for the build. This project involved an extension to the rear of the property and updating the décor of the ground floor to create a cohesive space for the owners who love entertaining and welcoming friends and family into their home and garden. The property is in a conservation area so we took this into consideration when proposing updates to the structure and layout, all of which were successfully approved without need for modification to our plan.   Chris Snook   For this extension, we retained as much of the brickwor...

Poetic and resonant Carthona House informed by Brazilian modernism

In Sydney’s Olympic Park neighbourhood, ‘complement by contrast’ is the approach taken to the design of this project. The original Federation-style house is a heritage-listed item of local significance and remains in situ, while a new and strikingly black extension by Daniel Boddam is positioned as a distinctive and separate element. A courtyard separates the two buildings, providing light and air between old and new. Courtesy Daniel Boddam The design is largely informed by Brazilian modernist architecture, with which the client has a deep connection. The facades open and close as breathable skins, thus allowing for sunlight or shadow, privacy or connection. The open volumes and voids result in a dappled, dancing lig... More

Infill project in Brussels uses glass to create intriguing spatial transitions

In the centre of Brussels, an existing building from the beginning of the 20th century was located between two higher apartment buildings and forms part of a large urban building block. Filling the gap between the two higher apartments with an extension, dmvA Architecten have densified the site in harmony with the scale of its surroundings.  The urban infill portion includes a training centre and practice for advanced diagnostic imaging in dentistry and also serves as a home to the client.   Credit: Sergio Pirrone Making the most of its floor area, the different spaces inside the project can be used flexibly, making a combination of work and living uses possible. Spaces are able to transition with ease. For example, the trai... More
