Usually they don’t live in the country all year round. Come here for the weekend to relax, sometimes for the whole vacation. In the cottage in the attic, you can equip such a room for relaxation, as in the photo.
To prevent indoor heat in the summer too hot and cold in the fall, it is recommended that the roof be insulated, even during the construction phase of the house.
A variant of insulation can be mineral wool. For vapor barrier use a special film. Then there will be no need to use air conditioning in the summer, just open the window. In autumn, you do not need to additionally heat the room. The insulation, among other things, is also soundproof, which will make the room even more comfortable.
The unusual design of the room is achieved due to the fact that the beams and rafters are used as interior elements.
