Scope and exclusions
This black shell includes the foundation and ground floor slab, concrete frame, external masonry, roof, external windows and entrance doors. White shell usually adds rough services and plaster; green shell adds further preparation; turnkey adds interior finishing. These scopes vary by contractor and are not priced here.
Excluded: internal partitions, stairs, interior finishes, internal electrical/plumbing/heating, yard, furniture, appliances and kitchen. No retaining walls or slope work. Complex soil requires a project-specific estimate.
Assumptions and geometry
Gross = living area x 1.12. Perimeter = 4 x sqrt(gross floor area) x 1.15. Openings = 21 percent. Roof covers the largest floor; pitched area factor 1.18. Upper-floor overhangs add 15 percent to frame quantities. Estimated geometry is not a structural design.
