We operate across all London boroughs including North London, East London, South London, and West London, plus surrounding areas like Hertfordshire and Surrey.

Standard applications typically take 8-10 weeks, though we often achieve faster approvals through our established relationships with local authorities and strategic submission preparation.
Can you help with listed building consent?
Yes, we specialise in navigating the complex requirements for listed buildings, ensuring preservation of historical features while achieving necessary approvals for modernisation projects.
What is included in your feasibility study service?

Report
Would definitely recommend for any detailed drawings required, we got them in late in the day to provide building regs drawings, were really efficient in completing within the required timescales and went into a lot of detail to make sure everything was right.

This helps us greatly when undertaking the structural design work on their projects. I would highly recommend Detailed Planning to any client who is looking for help with Architectural services.
