The Conservatory House (a.k.a. Home Tree House) located in Varna, Bulgaria, was designed by Ignatov Architects, is designed for the enjoyment of nature and music. The client asked for a residence with a space for hosting small music events and a large conservatory for growing flowers. These requirements were in line with local building code for rural areas which required a collateral agricultural use for granting a building permit.
The serenity of the surrounding nature inspired the architects to work toward restoring the initial equilibrium of the site. The resulting design solution fits the house into the existing quarry pit and makes the new structure as compact as possible. The house fills the void and becomes a retaining wall itself, allowing the restoration of the terrain around it.
Diagonal, vertical and horizontal structural elements on the southern and eastern facades follow the structural stress lines and reveal the building’s tectonics. A lack of cultivated landscaping promotes re-growth of local plant species and preserves the local microclimate. A bio-active wastewater treatment unit turns waste into bio-compost and irrigation water.
