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.

We love to design cabins, as they bring together so many of our design interests.

First, our predilection for architecture in remote (and often sensitive) natural locations, to create small thresholds where man meets nature, where minimal environmental footprint and limited access call for an economy of means.

And we are fond of designing tiny spaces — creating places rich in human interactions and intricate functions where people can really "key in" with the architecture, bringing back the simple joy of being together, sheltered from the elements.

But as importantly, cabins also act as social nodes where the complex community of the different generations in a family or in a group of friends congregate, each with their different needs, expectations and desires, making for a challenging but fascinating briefing process.

This redesign of a seaside cabin in Hvitsten, on the shore of the Oslo fjord, brought all these aspects together and was a nice counterpoint to our earlier design of a skiing winter cabin in the mountains of Hedmark.

About the project

As is often the case with Norwegian cabins, our clients for this project spanned over three generations. Initially built in the 1950s by the great-grandfather, the summer cabin and its small sleeping annex have been used ever since by the family for spring and summer holidays.

The extended families are now struggling to all fit in the cabins, which has become both too small and in need of repair. Now retired, the grandfather and his partner also want to use the cabin a lot more throughout the year, so they needed the uninsulated cabin to be upgraded for the winter climate and wished to have a real bathroom installed.

All had cherished childhood memories of the cabin and wanted to preserve as much of its exterior aspect and rustic character as possible. So, their requirement to comfortably fit in up to twelve sleeping guests for occasional extended family gatherings called for inventive remodelling and renovation, considering their tight budget!

Looking at the existing cabins

Perched against a steep rocky hillside overlooking the sea, the cabins face south-west into a breathtaking view of the Oslo fjord and its slow ballet of sailboats and cruise ships.

The Oslo fjord, as seen from the main cabin

In the main cabin, the small living room actually had a large window opening towards the fjord, but the kitchen and meal area — central to family life in the cabin — were situated behind it, in the darkest part of space of cabin, right against the rock face to the north. The other facades of the cabin were essentially blind because of a small hallway and the two bedrooms to the west. As a result, the main daytime social spaces had no visual connection with either the covered porch to the south-west or the sleeping cabin to the west, both of them often used in the mornings and evenings for informal meals and drinks.

Typical of spaces with light coming from only one direction, this configuration made the living room and meal area appear strangely gloomy, as the large window created a glare effect in contrast with the other darker and unlit interior surfaces. Built to look straight onto the fjord through this large window, the space had only short interior perspectives, making it appear more cramped and small than it actually was.

Situated a few meters downhill and to the west, the sleeping annex had a quiet simplicity to it, nested in the overgrown vegetation and straddling a small stream in the rocks. Unfortunately, an improvised shower had been installed inside a few years back without proper ventilation and created damp problems, so that in addition to being overcrowded, its sleeping rooms had also become uncomfortable.

Welcoming everyone

The initial plan was to integrate the existing porch into the main cabin, to create an extra bedroom. While this made sense to accommodate more guests, we all agreed that this compounded some of the existing problems, in particular closing off the main cabin from the fjord.

Turning the problem around, we actually removed one bedroom from the main cabin, thus keeping only one for the most frequent occupants of the cabin: the grand-father and his partner.

We carefully checked the feasibility of our proposal by preparing a comprehensive list of use scenarios, from one couple to up to fourteen sleeping guests! We found that moving the shower out of the sleeping annex, ventilating it properly and making some slight adjustments to its interior layout and bedding would allow eight people to comfortably sleep there. All this could be done at minimum cost, so that most of the available budget could be dedicated to the main cabin.

Now remained the task of optimising the shared daytime spaces in the main cabin. And this was essential: every parent can imagine the intense atmosphere when up to three families, including young children, are stuck together indoors for a whole rainy afternoon! Thus, in addition to creating functional living quarters, we also needed to organise sub-spaces within this small cabin, so that everyone could define his or her comfortable own space.

A niche in the rocks

We approached this task from two different angles.

Our design strategy for the remodelling the main cabin, drawn over the plan of the existing cabin (click for full size).

First, we created two different sub-spaces: one for the adults, facing the fjord, more social and relaxing, and one more playful for the children, cradled against the vegetation of the shaded cliff face. These two spaces intersect around the dinner table, the natural converging point for the whole family.

Then, we connected these spaces to the outdoors by nesting these sub-spaces around generous openings — not just towards the fjord, but also towards the sleeping cabin wrapped in overgrown vegetation down to the west, the mossy rocks at the north and the sunbathed terrace to the south — to create a dual feeling of spaciousness and enclosure.

Although the main living space remains compact, it feels opened to the light patterns and textures of its natural surroundings.

Frequently eating out during the summer months, the kitchen and dining area extend out onto a terrace that is stepping down, so as to maintain unobstructed views of the sea horizon, even when terrace parasols are used or the large awning on the south facade is deployed. The terrace also acts as a connecting point between the main cabin, the play garden and the shaded path to the sleeping cabin.

Fitting it all together

Space was very limited inside the main cabin, so we concentrated most of the storage along the west wall, designed as a large oak surface perforated by the kitchen and large window niche where children can sit and play. To make sure that everything fitting nicely, we produced a detailed specification for these densely fitted interior — both in Norwegian and in English, at the clients' request.

We love to involve our clients in the building process. And since one of them is keen on woodworking, we had a design session together to develop together the design of open screen between kitchen and sitting, which also will also integrate coat/shoe storage, seating, a book shelf and the TV equipment. He will later on build it himself.

The very basic existing drainage and electric systems were upgraded to cater for the new bathroom and appliances. The cladding was damaged and needed replacing, so we insulated the whole building fabric and fitted new energy-efficient windows. Along with a flexible shading system and ample provisions for natural ventilation, our clients will be able to enjoy their cabin all-year round!
