From first sketch to signed-off Building Regulations drawings — we design extensions, loft conversions, HMOs and new-build houses that get approved and get built.
100+ projects approved · Hounslow, Ealing, Hillingdon, Richmond, Brent, Harrow, Hammersmith & Fulham, Kingston, Surrey & Buckinghamshire
From planning permission and lawful development certificates to Building Regulations, structural coordination and photorealistic 3D visualisations, we provide everything needed to take your project from concept through to construction.
Every project follows a carefully managed process that takes your ideas from the first consultation through planning, technical design and construction-ready drawings.
Discuss your ideas, project goals, budget and planning requirements so we can recommend the best approach.
We carry out a detailed measured survey of the property and assess planning constraints, site conditions and design opportunities.
We develop concept designs into detailed architectural proposals, refining layouts, appearance and functionality.
We prepare and submit all planning documentation, drawings and supporting statements while managing communication with the Local Authority.
We respond to planning officer comments, make amendments where necessary and manage the application through to decision.
Once planning is complete we prepare detailed Building Regulations drawings, construction details and technical information ready for Building Control and construction.
Explore a selection of planning permissions, house extensions, loft conversions, flat conversions and commercial developments completed across West London and the surrounding counties.
Whether you're planning a house extension, loft conversion, new build or commercial development, our team can help turn your ideas into buildable, planning-ready designs.
Every application is pre-screened through ArchLens AI, our in-house planning-risk tool, before it ever reaches a planning officer's desk — flagging policy conflicts early so submissions go in clean the first time.
