Specialised in
Planning drawings show what you want to build. Technical drawings develop the details your project needs for Building Control review, builder pricing and construction.
We prepare Building Regulations drawing packages for London extensions, loft conversions, refurbishments and new homes. The scope is tailored to the project and can cover layouts, sections, construction details and specifications.
We coordinate with structural engineers and other appointed specialists, identify information still needed and respond to Building Control comments within the agreed scope. Each consultant remains responsible for their own design.
Send your approved plans or current drawings for a clear quotation. We will confirm the deliverables, required specialist input and expected turnaround before starting.
With over 25 years of experience, Horizon Architecture brings together architectural design, interiors and technical coordination. We work with you to understand the property, compare options and develop the information each stage needs. Clear fees, fast responses and an agreed programme keep you informed as your project moves forward.

Use our free construction cost calculator to check a rough estimate of how much your extension, loft conversion, refurbishment or new-build project could cost. It is an early budgeting guide rather than a contractor quotation.
