Some marketing visualisations we produced for our developer client, for a new build house we designed last year. With a planning application granted, building work should start this summer.

Portfolio project
From basement to master wing

Thibaut Devulder

Our transformation of a family house in Oslo in now complete and our delighted clients can move into the brand new master wing of their home, converted from an existing disused basement.

The brief

Our clients wished to create a parent wing to their family home — a single floor on a two-unit house in Oslo. The new quarters were to accommodate their new master bedroom, together with a comfortable bathroom, home office and kitchen space. With the children growing up, the clients also liked the possibility of renting out part of the house in the future,

It was not possible to extend the house further onto the site, but the apartment had access to an existing basement, mostly unused. This low ceiling space was dark and uninsulated, and therefore cold and damp, and had no fire escape. High levels of radon gas were also measured in the underground space, making it further unsuitable to use as a living space. To complicate matters, this basement could only be accessed through a steep staircase, from a shared area outside the flat.

A new wing, filled with sunlight…

We focused our approach on creating new spaces that felt integrated into the existing home, with a sense of privacy yet avoiding the common claustrophobic feeling of converted basement spaces.

Since the conversion of the basement needed new fire escapes, we made the most of these required new openings, transforming them into landscaped staircase and planted light wells, bringing daylight and views from the garden deep into the new spaces. Transforming technical constraints into creative opportunities!

With minimum changes to the existing structure and services of the house, we relocated the staircase to the inside of the flat, connecting the new space below to the existing circulation, so that it became a natural extension of the home. All technical functions were concentrated in the middle of the plan, with a large bedroom, home office, gym space, kitchen and modern bathroom wrapping around them along the new large windows. Deeper into the floor plan, where no daylight could be brought, we tucked efficient storage space for the family.

The new lower floor has generous access to the garden, through a cascading timber terrace, transforming what could have been a dark access staircase into a attractive and private exterior space, streaming sunlight into the new bedroom.

Comfortable and future-proof

Our remodelling strategy integrated a full upgrade to the basement fabric, adding high insulation levels in the new lowered basement floor and existing walls — greatly improving both thermal comfort and energy efficiency — as well as in the ceiling to create acoustic privacy from the upper floor.

In the long-term future, renting out the lower floor as a separate apartment will be as simple as closing a couple of doors, to separate a fully living unit equipped with kitchen, bathroom and wood oven, and with direct access from the street through its private terraced exterior staircase.

 

Early in the design process, we developed technical solutions to bringing daylight and thermal comfort to the basement, later specified in details for the tender documents and the construction phase

We have just collaborated with Ur Arkitekter on a prequalification entry for the masterplanning competition of the Møllenberg neighbourhood in Trondheim, Norway..

Rethinking the identity and social dynamics of this historical neighbourhood in the centre of Trondheim — today mostly populated by students — our concept proposal explores how communal urban farming can be used as a catalyst to foster social diversity and renew community engagement in the city.

Natural clay floor

The finished clay plaster floor

Hands-on course last week at our collective work space Kroloftet in Oslo, where I got a chance to practice natural clay flooring techniques under the guidance of our collaborator Kristian Møystad Bjørnland (of Ur Arkitekter) and Marc Charneau (of Kroloftet).

This little practical exercise aimed at resurfacing the unfinished floor of one of our meeting rooms, exploring clay plaster mixes, workmanship and surface treatments to create a natural, durable and, of course, beautiful floor.

We aimed are reclaiming as much existing materials as possible: taking as a starting point the strangely laid out parquet in the middle of the room over a rough concrete floor, we collected unwanted clay materials from our ceramics workshop, waste wood shavings from the wood workshop and hand sifted sand from a local quarry to experiment with various mix of clay-sand-fibre-water.

After an initial layer of clay mix compressed in place, we progressed through several layers of finer clay mixes to achieve a smooth end result. Since we used reclaimed materials of uncertain composition, we decided to experiment with various mixing proportions, some of which more successful than others, which gave us a chance to practice our reparation techniques on the less optimal mixes that developed cracks upon drying!

We finally applied a coat of boiled linseed oil and wax, purchased from the local building conservation shop, to seal and harden the surface.

The workshop was rich in discoveries and allowed me to experience the theory and process behind clay plastering.

With beautiful moisture control abilities, low embodied energy and full recyclability, we are looking forward to applying clay plastering techniques to create stunning and durable interior finishes for our future projects!

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.

Portfolio project
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!

Oslo study trip

Tom Hughes

The UK office of 2hD took a short trip to Oslo this month to study some of the city’s new building projects as fresh inspiration for our own practice. We teamed up with Simon of Simon Middlecote Architects — a long term collaborator, both in teaching at NTU and more recently on the Care Leavers’ Accommodation project (more on this to follow).

 
 

Some highlights included the Oslo Public Library by Atelier Oslo and Lundhagem Arkitekter. This huge building somehow feels inviting and warm, and people really seem to feel they belong there. The top-lit atrium connects spaces into a seamless experience without dominating the small scale and intimate areas that surround it. Facilities that we couldn’t dream of having in a public library in Nottingham, such as 3D printers and makers’ spaces with sewing machines and large format printers support locals to be creative. The books meanwhile are everywhere — within touch as you journey around the building but the shelving never dominates.

The overall impression is that you are likely to find interesting books by chance, whilst a digital navigation system guides you when you are looking for something in particular.

 

On Simon’s suggestion, we took a ferry across the harbour to visit the Norsk Folkemuseum and its collection of timber historic buildings salvaged from around the country. It was a great counterpoint to the fast-paced development around the harbour. Beautifully crafted and functional farmsteads, churches and civic buildings gave a sense of a more peaceful time, but also a reminder of the rapid development the country has undergone since the exploitation of its oil resources began.

 

Oslo is a unique mix of fjord-side port, with thriving, dynamic urban communities and peaceful suburbs enveloped by well-used and highly valued areas of natural environment.

Whilst not without its problems, there is a lot we can learn from the city about making workable, humane and happy urban places.

Prototyping with the CNC router

Thibaut Devulder

We have now access to an amazing CNC router at our new office space at Kroloftet. I tested it today for the first time, initially to fabricate some simple wooden gears for a homemade “analog music sequencer” I am developing for our next Ooo-Ya-Tsu art project (more in this later…)

The wooden gears, cut on the CNC router, with MIDI music “encoded” into grooves on the right

These gears were modelled in SketchUp and imported into AutoDesk Fusion, before being sent to the CNC router for fabrication. The geometry for the round grooves on one of the large gears was generated by a computer program I coded in Processing that reads musical MIDI files and convert them into 3D shapes, which can then can be grooved into the gears, effectively “encoding” the music into the wood. Fairly simple to start with, but it worked, so on with the prototyping!

Many thanks to Peter Magnus, expert digital fabricator at Kroloftet, for the heads up on using this amazing machine!

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!
