About Maven
Planning clarity and high-quality construction — one accountable team
Maven Design & Build exists to reduce the two biggest homeowner risks on residential projects: choosing the wrong planning route, and appointing a builder who cannot execute detail on site. We work with homeowners who want clear advice, disciplined documentation, and a build that matches what was promised.
Our background combines Permitted Development and planning judgement with hands-on delivery — extensions, loft conversions, renovations, and structural work — run under structured programmes and clear communication.
Whether you need help from the earliest feasibility stage or you already have planning and need an excellent builder, we align the process to your situation — without generic sales noise.
How we work
- 1
Feasibility & route
We check PD, prior approval, LDC, or full planning against your plot — with honest flags before you spend on the wrong design path.
- 2
Design & approvals
Survey, drawings, and coordinated technical detail so what is approved can be built on site without costly rework.
- 3
Managed build
Structured programme, clear communication, and quality control on structure, weathering, and finishes — with a client portal for stages and progress photos.
- 4
Handover
Snagging, building control sign-off where required, and documentation you can rely on at resale or remortgage.
Where we work
Based in Chelmsford, Essex, we deliver projects across Essex, Kent, and the London fringe — including boroughs and towns where terraced streets, party walls, and conservation constraints need careful handling. UK-wide video consultations are available for planning route advice; site visits are offered around our core operating area.
