Summary of the structures used in studied design solutions studied

	Built as usual (BAU)	Design for Disassembly (DfD)
Structure type	Conventional: Load-bearing wall structure on outer perimeter of the building and between apartments	Hybrid frame: Load-bearing wall structure between apartments, framed structure on outer perimeter
Foundation	Reinforced concrete piles, cast-in-place footing, concrete plinth elements	Reinforced concrete piles, cast-in-place footing, concrete plinth elements
Base floor	Ventilated base floor, insulated hollow core slab	Ventilated base floor, insulated hollow core slab
Intermediate floors	Hollow core slab, floor screed. Lower slab for bathrooms and balconies to be poured on site	Hollow core slab, floor screed, EPS board for underfloor heating. Separate bathroom slabs with integrated slab hanger, supported with steel brackets from adjacent HCSs or walls
Bearing walls	Load-bearing reinforced concrete elements between apartments	Load-bearing concrete elements between spaces with intermediate floors supported by a removable steel frame
External walls	Precast load-bearing concrete Sandwich element, brick tile exterior	Non-load-bearing, frame-supported, wood-framed, thermally insulated prefabricated element, wood cladding
Balconies	Exterior concrete slab anchored to the intermediate floor	Suspended balcony element with CLT panels as a load-bearing structure, anchored to a concrete frame
Roof structure	Hollow core slab, EPS and expanded clay insulation, in situ cast concrete slab, bituminous roofing	Hollow core slab, LVL-framed thermally insulated prefabricated element, bituminous roofing
