Extensions in Antwerpen
A rear extension or garden room gives an Antwerp townhouse the natural light and open living space it needs. We manage the whole journey: architect, planning permit, foundations, steel structure and complete turnkey finishing.
A home extension in Antwerp costs from € 2,200 per m² with a typical timeframe of 4 to 9 months. Van den Broeck Renovaties manages groundwork, foundations, thermal insulation, large sliding glazed doors and interior finish.

What is included
Every project in the Antwerp area is managed from start to handover following strict quality standards:
- Feasibility analysis, budgeting and planning application with an architect
- Earthworks, foundation footings or mini-piles and damp-proof membranes
- Traditional masonry or timber-frame construction
- Insulated flat roof with EPDM and optional skylight or lantern
- High-performance aluminium sliding doors (double or triple glazed)
- Turnkey interior finishing including underfloor heating, screed and electrics
Cost factors & budget drivers
The final cost of your project depends on several technical site parameters:
- Foundation type (strip foundations vs. screw piles for soft Antwerp soil)
- Dimensions of glazing and sliding door mechanism (e.g. slimline profiles)
- Integration of roof lanterns and skylights
- Soil removal and access logistics through the property
Permits & regional subsidies
Under strict Flemish rules extensions up to 40 m² may qualify for a simplified notification, but in urban Antwerp an official building permit with an architect is almost always required due to boundary walls. We guide your application smoothly through the municipal portal.
