Garage Conversions · DA5 Old Bexley
Bexley protects the Bexley Village conservation area, with its historic High Street and the River Cray setting, alongside standard suburban householder control across the rest of DA5.
The borough-level guide to garage conversions in Bexley sets out how the same work is handled across the rest of the authority.
Converting a garage in Old Bexley reclaims it as a habitable room — home office, bedroom or kitchen-diner — on DA5's semi-detached and inter-war stock. Most garage conversions are Permitted Development, but Bexley Council expects the parking and street-scene impact considered, and Building Regulations cover insulation, damp-proofing and the new floor and walls.
Turn your unused Old Bexley garage into a bedroom, home office or open-plan kitchen-diner. Planning route assessment, full building regulations drawings with Part L thermal compliance, structural calculations for any removed walls.
Across Old Bexley, Bexley Village, Albany Park fringe, North Cray fringe in DA5, the dominant property is inter-war and edwardian semis and detached houses around bexley village and old bexley, with cottages in the historic core. That stock shapes what garage conversion drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Bexley Council judges each on design quality and neighbour impact. We survey the specific Old Bexley property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the DA5 streetscape.

Listed, conservation or complex sites.
Yes. The inter-war and Edwardian semis and detached houses around Old Bexley suit side-return, rear and loft extensions. Within the Bexley Village conservation area changes need full planning with a Heritage Statement; outside it, much runs on the Permitted Development route, confirmed with a Lawful Development Certificate. We confirm which applies to your road.
Yes — the Bexley Village conservation area protects the historic High Street, the older cottages and the River Cray setting, so external changes there are carefully assessed and a flood-risk check may apply near the river. We design sympathetically and handle the Bexley application.
Usually yes on the semis outside the conservation area — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate. We check the head height and any village constraint, then draw the scheme for Building Control too.
With DA5 houses around £475,000-£750,000 and direct trains into London Bridge, a rear or loft extension adds family space worth above the build and drawing cost. Old Bexley's village setting is highly sought after.
Bexley Council charges its own statutory application fee (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every DA5 address.
For a DA5 project across Old Bexley, Bexley Village, Albany Park fringe, North Cray fringe, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Bexley Council (8 weeks for a householder application). We carry the Old Bexley application through every officer query to the decision.
Old Bexley (DA5) sits primarily in Bexley, so applications are decided by Bexley Council. Conservation areas within DA5 include Bexley Village, Old Bexley, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind garage conversion drawings in Old Bexley — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Bexley Council Building Control or an approved inspector. On DA5's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on DA5 homes.
Planning history and precedent stop at the borough line, so the comparable approvals nearby may sit elsewhere. See all services in DA6, DA7 and DA15.
Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
