Four Steps to Planning-Ready Drawings
Send Details & Invoice
Fill in our simple online form with your project details. We work directly from existing estate plans, architectural drawings, or your own measurements. We will then send your invoice—work begins as soon as it is settled.
You Measure, We Draw
Take photos and measurements yourself or use our easy-to-use app to capture the space. Our team then creates accurate architectural drawings and structural calculations tailored to your project.
Review & Approve
Review your draft drawings 100% online. Once you are completely happy, we will move forward with finalizing your project—all included in your fixed price.
Delivery & Submission
Within two weeks of starting, we will send your final PDF plans back, ready for submission to the authorities or building control approval.
What Our Clients Say
“Extremely professional and fast. TM Architectural Designs delivered our planning drawings well within the 2-week window. Council approved first time — couldn’t ask for more.”
“I needed structural calculations for a chimney breast removal. TM were responsive, affordable and the drawings were accepted by building control without any queries. Great service.”
“TM Designs provided their services much faster than any other architect I’d been quoted. Took a huge amount of stress out of my home extension project. Highly recommend.”
“Professional, creative and detail-oriented. Their drawings transformed our vision into something buildable and beautiful. The whole process was completely seamless.”
“Used TM for our loft conversion drawings. Very clear communication throughout, revisions were handled quickly, and the final package was exactly what building control needed.”
