A team of experts in urban planning, architecture, and law will handle your case from start to finish.

In Brussels, urban planning is governed by CoBAT, the Brussels Code of Spatial Planning. The Regional Urban Planning Regulations (RRU) set the standards for housing. Construction work carried out without a building permit constitutes a violation of urban planning regulations. This violation often comes to light during a sale, through a letter from the municipality, or as a result of a complaint from a neighbor.
The implications for a Brussels homeowner:
Our team is made up of experts in urban planning, architecture, and law. We have specialized exclusively in urban planning regularization since 1992.
In Brussels, each municipality processes applications for regularization permits on its own. The processing times there are notoriously long. Requests for additional information are almost always made. We prepare a complete application package at the time of submission to minimize back-and-forth correspondence.
You delegate. We evaluate the property, choose the right process, and follow the case through to the decision.

Since our creation in 1992, we have helped hundreds of customers to regularize their town planning infringements. Our success rate is over 95% and we have many positive references. Our customers are satisfied with the quality of our work and our affordable rates.
