We ordered an Ingrid 9,7 model from SelectHaus to serve a number of needs. In is the spill over accommodation for our country home. At other times it’s our relax area or spare work from home area, when I don’t want anybody bothering me. It fits in beautifully with the garden. Buying online from SelectHaus was easy as they helped us with advice to get it built, as we are only enthusiastic beginners.

We decided to get a Sigurdson 13,1. Initially as a yoga and exercise room, for myself and the girls. However, our guests love it! The 44mm solid timber walls and double glazing give excellent insulation in our sometimes-alpine climate. The whole process from ordering to completion was easier than we thought, and a quick price check showed that it cost way less than a similar competitor model with a glossy website. This is not anything like a shed!
