Geneva studio clavienrossier created this home in the Swiss Alps by adding two tinted concrete volumes atop the remains of a stone house and adjacent barn.

The project is located in Charrat in the Valais canton of Switzerland and involved demolishing much of the existing structure while retaining the original cellars and floors.

The two concrete additions have faceted walls, angled inwards towards an opening in each side.

Rooms in the new upper storeys are connected, with circulation around the edge of each volume.

Photographs are by Roger Frei.
Here are some more details from the architects:
Situated away from the village, this house included an adjacent barn and had a too vast volume to be renewed in its totality.

Only elements which can easily be reused were preserved, cellars and floors of the pre-existent house. The rest was demolished.

Volumes of visible tinted concrete replaced the double-sided roof and the transformed area.

The big openings so created allow the light to penetrate more generously.

The geometry of the superstructures results both from a formal desire and from a will to remove the wall thickness.

The various-slopes faces enhance the highly varied game of the shadows throughout the day. There are no corridors.

Circulation is made along the external wall, from room to room.

The overall view continues beyond the windows, opening onto the surrounding landscape.

I had the opportunity to visit the house during last swiss fortnight of architecture in May. Great idea, great contrast, and great execution.
archilocus, what is this swiss fortnight of architecture? does it take place every year?
i want this house…. … this is really nice!!!
It is quite nice combination between concrete and stone.Site is beautiful ;and concrete boxes seem like eyes opening to nature.
This is just brilliant. I am in love with Swiss architects! H&deM + Peter Zumthor!!
Get me a job!
the snow in the mountains mean its a cold area at least in winter, what kind of used in this house?
Great contrast
This is pretty cool, an imaginative and innovative combination of old and new. And I agree with "StillUnwritten" (above) about this looking like eyes opening to nature.
Minimal, essential. Many words in a great silence. Well done.
I see a mix of two very different houses.
This may be the finest house I've ever seen. One thing: are there really no walls enclosing the bathrooms?
I think they just haven't drawn the doors for some reason. Notice how there's no front door on the plans either.
quite a successful exercise in poetic architecture and minimalist restraint.
Like, congratulations.
Some time ago, our studio had a project with the same principle.
Unfortunately it was not built :-(
Today we are happy for someone to have had the opportunity to build something with a similar approach and that was very very well ;-)
Congratulations
Its realy fine.
our old skecth :-) http://spaceworkersemideia.blogspot.com/2008/10/0…
your scheme doesn't seem to be re-using an existing building, i might be wrong, which mean it isn't the same principle
The principle that he (Henrique Marques) is talking about is the same design that exists in the windows, those sloppy edges, not the idea of using and old building. Both ideas i like…
very sensitive to surrounding and context complemented with excellent details
yawn…reminds me of tibetan architecture
Nice house, shame the landscaping around it doesn't do it or the environment justice.
This is just brilliant.
I love the contrast
Ive never been this jelous of a home owner before …
What a project to add to what is probably a small but very respectable repertoire
Congrats on the execusion and builders
Stunning …
Another inspiring build by these Swiss architects. The house sits comfortably in the surroundings. Great use of materials
cannot imagine having sex in this house
is that how you judge all architecture? i use the same basis to decide what car to buy
Beautiful simplicity
By rights two contemporary concrete rectangular prisms plonked on top and aside of a traditional stone structure shouldn't work. But the softening of the facades by clever geometry gives the original a whole new aesthetic. Quite brilliant.
This house would blend in beautifully on our land in a small village called Ergazi in North Cyprus. I'd love to re-create it.
Love this project, a very remarkable design and how they managed to build a new concept over an old one… Clever is not enough, nor brilliant is the word fitting this is something else… Loved it…
