I’ve been working with AC Design Solution regularly for all my projects across London and couldn’t recommend them highly enough. They handle complex planning applications, basement conversions, loft conversions, house extensions, and mansion house projects — all under one roof. Every single project I’ve sent them has been approved through planning. The drawings are detailed, the applications are put together properly, and the building regulation drawings and structural engineering calculations are always accurate. As someone sending multiple projects a month, I need a practice I can rely on. AC Design Solution consistently delivers. If you’re looking for a practice in London that handles complex planning matters from start to finish — planning permission, building regulations, and structural engineering — these are the people to use.
