Architects in Welwyn Garden City.

AH Architecture is a chartered practice working in Welwyn Garden City and the surrounding area. We take a project from first idea to finished building: feasibility, planning, design and support on site, with one chartered point of contact throughout.

What we design in Welwyn Garden City

Welwyn Garden City is characterised by a planned garden city with protected layout and characterful interwar housing. That shapes what most projects here need, and we work across all of it.

  • Extensions

    Single and double storey, side, rear and wraparound extensions designed to be approved and buildable.

  • Loft conversions

    Dormer, hip to gable and mansard lofts, including permitted development and lawful development certificates.

  • New build homes

    One off houses and small residential schemes from feasibility through planning and technical design.

  • Planning applications

    Householder, full and change of use applications, plus pre application strategy built around the local authority.

  • Listed and conservation

    Listed building consent and conservation area work handled with the care and evidence these projects demand.

  • Commercial and mixed use

    Offices, retail and mixed use schemes that balance commercial return with design that lasts.

Planning in Welwyn Garden City

Approved is a local question.

Your application in Welwyn Garden City is decided by Welwyn Hatfield Borough Council, against its own local plan and policies. We design from those constraints first, because the same scheme can pass in one borough and be refused in another. Much of Welwyn Garden City sits within conservation areas, and some of it is listed, so even modest changes need careful design and often need listed building consent or conservation-area approval. We check the designation on your specific address before anything is drawn.

Before you spend heavily, our free tools give you an instant read on what your address might allow and what it could cost, and a free Clarity Call gives you a chartered architect's honest view on whether the project works.
