Planning Permission Without the Stress
Clients often wonder whether their home extension, loft conversion, or layout reconfiguration will require formal planning permission. While many residential projects can be completed under Permitted Development rights, London’s planning rules can be complex.
Typically, you will require formal planning permission if:
Your project exceeds Permitted Development limits:
For example, large loft conversions exceeding strict volume allowances (40 cubic meters for terraced properties, or 50 cubic meters for semi-detached and detached homes).
Your property is in a Conservation Area: Many London boroughs enforce strict local design codes to preserve the architectural character of the neighbourhood.
You are altering a flat or maisonette: These properties do not carry standard Permitted Development rights and almost always require formal council approval.
If your project does fall under Permitted Development, the process is incredibly efficient. However, you will still need a Certificate of Lawfulness (a letter of lawful development). We handle this entire application on your behalf, securing the legal paperwork you need before any building work begins.
Plans Approved First Time
Navigating local councils doesn’t have to delay your project. We handle the entire planning process for you, regularly liaising with local planning authorities across the capital.
Having successfully dealt with multiple boroughs, we know exactly how local councils operate, what technical details they require, and what is most likely to be approved. It is this deep architectural and local expertise that allows us to maintain a high first-time approval rate for our clients’.
Whether your project requires a full planning application or a lawful development certificate, we manage the red tape so you don’t have to.
