Sofia, Oborishte, Bulgaria

The Oborishte district is one of the older parts of the city of Sofia, the capital of Bulgaria. Within Oborishte, there is a mix of residential, commercial and office functions, as well as a mix of building types (pre-war detached houses and multi-family apartment blocks). This action envisages the renovation of five apartment blocks that are rather typical for building practice both in Sofia and Bulgaria around 1970. The buildings are prefabricated apartment buildings with 7 to 8 levels, locally known as ‘panel blocks’. Thermal characteristics of the constructions are very poor, large parts of the glazing are in a bad condition. The same can be said for the commonly used parts of the blocks.
