We always try to source materials locally both as a means of supporting the regional economy and keeping travel distance to a minimum. Most of our components are either made or supplied by Devon-based companies. All our timber is from sustainable sources managed by the FSC (Forest Stewardship Council).
Our preferred cladding material is treated Siberian Larch which we source from Norclad in Bristol. Larch is a tough and durable timber with a beautiful grain and texture. Our cladding is machined to a custom profile to give a crisp shadow gap between boards and fixed to the frame using stainless steel screws.
Interior walls, ceiling and floor
The interior is clad in birch-faced plywood. This is very different from building-grade ply. What you see is a solid birch surface with an attractive grain and a warm colour. See options for info on finishes.
Our windows are double-glazed using A rated toughened glass and have a douglas fir frame built by Buildpoint Joinery in Totnes. Douglas fir, like larch, has a strong grain and is suitable for exterior use. The frames are finished in two coats of Osmo natural oil woodstain. The advantage of oils over paints is that they soak into the timber and ‘nourish’ the grain rather than just sitting on the surface. Osmo is a German company with a strong environmental ethos.
All of our panels (roof, walls, floor and door) are filled with 100mm Knauf Earthwool insulation. Earthwool is a great improvement on traditional mineral fibre insulation. It is safer to handle and achives an A+ rating from the BRE (Building Research Establishment) which looks at the whole energy cost of building materials.
An unusual feature of the Mökki studio is the complete separation of the waterproof layer (a profiled metal deck) from the thermal layer in the roof construction. This is a building technique that is often used in hot climates as it avoids the transfer of heat from the sun into the room below. Like plywood, profiled metal is often seen as a humble and utilitarian material, but it has frequently been used to great effect, especially in the modern architecture of Australia and New Zealand. See Herbst Architects for example.
