The Planning Process Shouldn’t Cost You Time, Money or Sleep

Most homeowners start a project full of excitement and quickly hit a wall of planning jargon, council red tape and unresponsive designers. Without the right local architectural expertise, delays and refusals eat into your budget and your patience.
  • Struggling to understand what you can and can’t build under local planning rules.
  • Fearing a rejected application after weeks of waiting and wasted fees.
  • Chasing architects who are impossible to get hold of when you need answers.

Used for Rear single storey extension & garage conversion; very pleased; Daniel is so lovely & easygoing to communicate with and has made the whole process so effortless. Planning was approved a lot sooner than expected.
Being Plight

Chris and Paul were great, we were very happy with the whole experience. They helped us redesign our flat, including adding a side return and rear extension, and paid close attention to what we wanted. They sorted all the pre-construction admin and were responsive during construction itself, which was much appreciated.
Steve Cuss

We’ve used Detailed planning twice now. Great team, thanks!
Oliver Gillon

Paul was an absolute pleasure to work with. He helped us make the most of our home, offering thoughtful ideas and practical solutions throughout the process. We’re delighted with the result and would happily recommend him to any of our friends and family.

Frequently Asked Questions.

We believe in complete transparency. These answers explain exactly how we take your project from idea to approved plans.
Are you architects?
Our team includes Chartered Architectural Technologists registered with CIAT and works alongside an ARB-registered architect. We deliver the full design, planning and technical service you’d expect from an architect — often at more competitive fees.
How much do your services cost?
We work on fixed, transparent fees agreed upfront after your free consultation, so you’ll never face surprise charges. Your quote reflects your specific project and scope.
Will I have a dedicated point of contact?
Yes. You’ll work directly with a designer who knows your project, and who’s genuinely easy to reach throughout — a common frustration our clients tell us they had elsewhere.
Do you handle the planning application for me?
Absolutely. We prepare the drawings, submit the application and liaise with your local council, managing the process to give your project the best possible chance of approval.
Which areas do you cover?
We provide architectural services across North, East, South and West London, plus Hertfordshire — including Barnet, Enfield, Finchley, Southgate, St Albans, Potters Bar and surrounding areas.
Can you just draw up plans if that’s all I need?
Yes. If you only need drawings for your extension, loft conversion or renovation, we offer that as a standalone service tailored to your requirements.
