Basement and attic conversion project management (Kellerausbau and Dachausbau)

Is the demand real?

Space is scarce and expensive in Swiss cities, so converting an unused attic or basement into living space, an office, or a rentable unit is a high-value way for owners to add square meters without moving. The work spans permits, structural, insulation, and multiple trades, which overwhelms homeowners, and most general contractors will not manage the messy coordination cleanly. The buyer has serious budget, and a fixed-fee project manager who delivers the conversion turnkey is a scarce, high-margin offer with no inventory risk.
