Over in Stockholm, Sweden, the mercury tends to drop to less than -3°C (27°F) on average in January, and hence, Marie Granmar and Charles Sacilotto decided that a house within a greenhouse is the best way to ensure that heat gets trapped within, making sure the house remains nice and warm. Sacilotto was no doubt inspired to come up and realize this idea thanks to architect Bengt Warne, who was the first to design the Naturhus (Nature House) in 1974.
Covering the old summer house with 4mm glass and basing it on Warne’s design, there is still a whole lot of room to roam around in the wrap around garden thanks to a greenhouse footprint that is close to double that of their home.
