DESIGN
BUILD
At Payte Architect London, every loft extension project begins with a measured survey of the existing property. This allows us to accurately assess the roof structure, head height, and layout before any design work starts.
For many loft conversions in Highgate, the project can proceed under Permitted Development Rights. In these cases, we prepare and submit an application for a Certificate of Lawful Development, providing formal confirmation from the local authority that the proposed loft extension is lawful.
Following this, we develop the architectural design, including space planning, staircase layout, and any roof alterations required. Detailed technical drawings are prepared alongside structural calculations for steel beams and floor strengthening. All documentation for Building Control is also coordinated by our team.
Our design and build loft extension service in Highgate is delivered for a single fixed price and includes project management and construction through to first fix stage. This typically involves structural steel installation, dormer or roof construction, weatherproofing, windows or roof lights, staircase formation, plumbing, heating extensions, electrical wiring, and internal partitions.
Our architects practice also acts as both Principal Designer and Principal Contractor under the Construction (Design and Management) Regulations 2015, ensuring safety, compliance, and coordination are managed throughout the project.
