Construction started in Hagalykkja

Thibaut Devulder

Building work has started on our family house remodel in Eidsvoll. with the timber framing of the new extension now completed.

In this first phase of the construction process, this extension will be fully built and fitted with a new kitchen connected to a winter garden, before being integrated into the house. The second building phase will then start, whereby the old kitchen will be converted into an accessible master bedroom and a new modern bathroom.

This careful phasing informed the design process and was developed in collaboration with the clients to minimise disruption to the family life, allowing them to continue using the house throughout the construction period.

Our proposed new approach for the house, as seen from the street

As part of a larger remodelling and refurbishment of a family house in Vinterbro, we have put a particular focus on redesigning the house approach from the street, linking a new accessible and welcoming entrance to the home with a new woodworking workshop and garage.

The kitchen is the heart

Thibaut Devulder

For this project, we helped our clients remodel their home to create a vibrant and flexible social space at its heart, where the whole family could share meals, be creative, work and entertain friends around a large communal table.

Getting to know the existing house

The couple with their twin daughters had lived in this house, located in Bærum — not far from another remodelling projects of ours, for six years before they decided to remodel. Originally built in 1921 as a log house, it had been extended and altered several times over the course of a century.

The most recent of these extensions had caused the sole window of the existing small kitchen to be closed off, so that the only daylight was coming through an adjacent playroom. The neighbouring living-room, with its large windows towards the garden, was mostly used as a TV and music room. Despite its comfortable size, this room was surprisingly difficult to furnish, in part due to an awkwardly placed door to the outdoor terrace, and the large dining table at its centre was only used for occasional festive occasions.

Our analysis of the existing ground floor of the house

Developing a design brief

We sat down with the family to explore their needs and aspirations for their home, bringing in fond memories of former homes they inhabited and loved, and created together a concise brief for this project. Concentrating on three rooms on the ground floor, we were to create an attractive social space at the centre of the house, well connected to the beautiful garden and filled with daylight, to be shared by all members of the family for their daily activities: making food, sharing meals together and with guests, handicraft, playing the piano, doing homework (or home work!), etc. Occasionally, the family should also have the possibility to close off part of the ground floor when multiple activities should be kept separate.

Transforming the house

… and our design strategy to transform the spaces, explained step-by-step

With a clear brief defined, and the house carefully analysed, a solution to unlock the potential of a home can be sought. A seemingly simple change can thoroughly transform the way the home is being inhabited.

With minimal structural changes to the house, we reorganised the internal partitions and windows to create a spacious room with a large communal table as its centrepiece, wrapping the kitchen area around an existing chimney. This creates a unified space while maintaining a gradation of privacy between the more discrete food preparation workbenches of the kitchen, the central table and the desk area close to the new wood stove.

A large French door, aligned with the kitchen benches, opens views and easy access to the garden, seamlessly extending the dining area onto the large terrace outside.

The fully shelved partition, which accommodates on the kitchen side the bookshelves and communal desk space, and on the living-room side the television, creates a soft boundary between the social kitchen and more private living-room, which can be fully shut off by a hidden sliding door when required.

Our proposed new ground floor layout

With the large TV screen discretely tucked out of the way into the new partition, the space in front of the large living-room windows becomes a sort of winter garden overlooking the green areas outside, with a breakout sitting space filled with daylight and plants.

Between this interior “garden room” and the open terrace outside is the covered porch, now free of circulation and transformed into a sheltered sitting corner. Whatever the weather, there is always a comfortable place to sit and enjoy the garden!

And as with most of our projects, the remodelling work was also the opportunity to upgrade the comfort and energy efficiency of the building in a cost-effective manner, allowing for further external insulation of the walls when the external cladding needs changing in the future.

“2hD approached our ideas with a completely fresh eye. They came up with a solution which, in retrospect, feels simple and natural, and yet completely changed the way we use our home to be together!”

We are delighted to announce that our remodelling and extension of a house in Bøler has been granted planning permission by Oslo Kommune.

The post-and-beam timber house, designed by architects Karlsen & Westbø
 in 1979, sits on a beautiful plot sloping into Bølerskogen, a wilderness reserve on the brink of lake of Østensjøvannet, in Oslo.

We are looking forward to finalising the detailed design and the interior design with our clients!

Building work on our remodelling of a family house in Gjettum has now started. The walls have been stripped, revealing the log walls of the original house, before the key change to the structure is reorganise the kitchen and living-room.

We have also done an updated survey, so that the furniture and benches of the new fitted kitchen can be produced.

Credits to our clients for tackling the demolition work themselves!

Roof garden under construction

Thibaut Devulder

After getting planning permission more than a year ago , the roof terrace we designed on top of a residential building in central Oslo is finally under construction. The work on site is taking place under a “roof over the roof”, so that the construction of the new staircase and roof garden can take place with minimum disruption to the inhabitants.

Samba in the stair

Thibaut Devulder

Following our complete remodel and extension of their cabins in Hvitsten, overlooking the Oslo Fjord, our clients asked us to also fit an extra living space in one of the little annex buildings on the site.

The tiny cabin that we designed accommodates a play space for the children during daytime, a small workstation, sleeping space for two adults and two children, as well as a small terrace for summer breakfast overlooking the fjord. To reach the private sleeping space tucked up over the small living-room, we custom-designed a compact alternating tread stair, called sambatrapp (“samba stair”) in Norwegian, which also doubled as a bookshelves for the desk underneath.

We love working on self-build projects and custom-made furniture, so we were thrilled when our client announced that he wanted to build the stair himself. As with our custom-made screen wall in the main cabin, we developed in collaboration with him alternative designs for the stairs, adjusting the design to joinery techniques he mastered, to produce a full cut-and-assembly manual to build the stairs.

A visit to the summer cabin in Hvitsten we remodelled and extended a few years ago. The little annex cabin and terraced landscape that we have just finished designing are now in the process of being built. The landscaping on this steep site overlooking the Oslo Fjord is really bringing together the different indoor and outdoor spaces, happily used by three generations of families and friends!

Portfolio project
Vertical living in a former boiler house

A pod-like extension provides services, daylight and ventilation.

This intriguing little project is now under construction in Nottingham. Our client’s town house occupies part of a former builder’s joinery workshop in a Conservation Area. Entry to the main house is through the ground floor of a free-standing former boiler house, complete with an 11m high brick chimney. Our challenge was to re-purpose this special, tiny building to contain a home working office and guest accommodation.

We stripped out and redesigned the boiler house interior to fit a mezzanine level under the opened-up roof structure, and used ‘space saver’ stairs to maximise the floor area. The tiny floor plan is offset by an impressive vertical connection between the levels- with everything needed for occupation accessed off a vertical circulation route culminating in the bed platform.

The temptation is to cut lots of holes in an existing building to let in light, provide ventilation and create new service routes, but in this case we decided to preserve the integrity of the boiler house by adding a highly-serviced pod to the exterior. This provides the necessary service connections, and brings light and ventilation to the interior. The addition is anonymous, in keeping with the industrial heritage of the building whilst creating intrigue and mystery of its own.

Portfolio project
A family home in Jar

Thibaut Devulder

Long perspective across the living spaces in the remodelled home

We have just completed the extension and remodelling of a family apartment in Jar, a close suburb of Oslo.

Our clients wanted help to expand their family apartment on the upper floors of a two-family unit that had become too tight for their growing family. In particular, the main living space, which served as a kitchen, dining-room and living-room was over-crowded and awkwardly placed next to bedroom of their three year old daughter. Ancillary spaces were also impractical and a separate washroom was needed to free up space in the bathroom.

Having analysed the existing spaces, we understood that this small extension project could really unlock the potential of the whole house: creating a welcoming and accessible entrance, activating the unused circulation spaces and restoring the connection to the garden — all without increasing our clients’ initial budget.

Our design approach

The remodelled home

We wanted to create a feeling of spaciousness and diversity inside the apartment. This is achieved by opening long perspectives across the whole house, visually linking strings of distinct spaces along them.

A new porch shelters the approach to the house and frames the entrance to the new hallway, now with level access from the exterior. This view extends across the high ceiling space and through a glazed door, all the way to the pergola in the garden. To the side, a more subdued space links the wardrobes to the new washroom.

With the extension of the house, the preserved staircase is now located at the centre of the house and acts as a vertical axis serving four different sub-levels, between the ground and upper floors. These help breaking up the height into a series of separate, yet connected spaces, so that the different floors feel more unified into a whole.

This feeling of diversity is further echoed on the horizontal axis, with a long perspective across four distinct spaces on the upper floor — through the dining-room and the staircase, the new study and TV-room, eventually opening up to the evergreen vegetation outside.

The exterior of this extension integrates seamlessly with the existing structure of the house, both in volumes and materials. Yet, despite its modest scale, the addition of the extension restructures the house to give a sense of spaciousness and spatial diversity to the interior, creating a more flexible home for this family.

“2hD really listened to our needs and ideas. And they managed to integrate them in their design thinking to completely transform our apartment.

We didn’t expect this project to have such an impact on how we experience our home. It used to feel like a small apartment. Now it feels like a spacious house!”
