3 Bygg Mester is a Norwegian residential developer affiliated with Norgeshus. It plans and builds homes within its own housing developments, using Norgeshus concepts as the basis for project design and construction.

Services cover development planning, adaptation of selected layouts, local building work and completion of residences for sale in planned neighbourhoods. The company focuses on controlled developments, including Borgen Vest, rather than individual building contracts on customer-owned land.
