A premium countryside residence, this project began with a client-provided concept and selected site in the Altai Mountains, followed by full design development and construction planning by KUB HOUSE. The plot was characterized by unstable soil conditions, significantly increasing seismic risk. Structural calculations confirmed a Seismic Hazard Level 9. Additionally, the concept called for a cantilevered second floor to appear as if floating over an artificial hill. A major design challenge was the client’s request for large operable glazing—to the extent that they wished to sleep with the entire wall open to nature. Another critical requirement was maximum energy autonomy. The site was limited to just 5 kW of grid power via an old transmission line, with high risk of outages.
Engineering Solutions:
Reinforced foundation system using large-diameter bored piles
Load-bearing raft slab engineered to support the cantilevered terrace
Above-ground structure: hybrid steel–CLT construction, with all steel
elements fully concealed
Interior design gives the impression of a fully timber house
Energy & Autonomy:
Solar panel array
Four-pipe air-to-air heat pump system
Underground LPG tank (gas holder)
LPG backup generator
Designed for full off-grid operation, with only one LPG refill per year
