Walloon Brabant pitfall to avoid

The RGBSR regulation and heritage constraints.

A large part of Walloon Brabant lies in RGBSR zones (General Regulation for Rural Built Sites) or within a heritage perimeter. This imposes materials, massing and colours. Make sure the permit is finally issued and clear of any appeal before any payment beyond the 5%.
