Architectural Design Across Cambridgeshire

Independent architectural design practice providing end-to-end planning drawings, barn conversions, and home extensions throughout Cambridgeshire.

Binney & Sims Design provides complete architectural design services across Cambridgeshire, guiding homeowners from initial sketches to planning approval. Based locally since 2013, our team handles house extensions, barn conversions, and new builds suited to rural fenland hamlets, historic city centres, and expanding commuter villages.

Architectural design for Cambridgeshire homes and rural properties

Cambridgeshire has a diverse built environment. In historic areas and market towns, strict conservation policies protect period streetscapes. In the rural countryside and the Fens, agricultural buildings require a sensitive approach to convert functional structures into comfortable living spaces. We understand how local planning authorities assess proposals across both urban and rural settings.

What residential design services do we provide in Cambridgeshire?

We support homeowners through every stage of altering, extending, or building a home. Our end-to-end process covers initial measured surveys, concept drawings, building regulations, and submitting applications to local councils.

Period property extensions and heritage renovations

Many homes in Cambridgeshire feature traditional timber framing, soft red brick, or clunch stonework. Adding modern living space to these homes requires balance. We prepare heritage and listed building designs and tailored house extensions that respect original features while providing open-plan kitchens, light-filled living areas, and practical layouts.

Sensitive barn conversions

The fenland landscape and surrounding farmland contain distinctive agricultural barns ripe for residential conversion. We design sympathetic schemes that retain structural timbers, brickwork, and roof pitches while adding modern insulation, glazing, and utilities under Class Q permitted development or full planning permission.

Modern family homes and commuter village extensions

Expanding villages surrounding Cambridge and Huntingdon see continuous demand for family space. We work on detached, semi-detached, and modern estate properties, creating loft conversions, two-storey additions, and wrap-around kitchen extensions that accommodate busy family routines.
