Detached house extension in the Netherlands - design, costs and permits
A detached house extension gives detached homes room for larger, more individual layouts such as a suite, studio or generous kitchen. We design, plan and build it with clear advice, fixed pricing and one accountable team.
This page explains the main choices for a detached house extension: layout, materials, budget, planning and whether a permit is likely to be needed.
With more freedom comes more design responsibility: scale, sightlines, roof form and landscape connection matter.
