Across Penge, Anerley, Crystal Palace Park fringe in SE20, the dominant property is victorian and edwardian terraces and villas around penge and anerley, with mansion blocks and post-war pockets near the crystal palace park. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Bromley Council judges each on design quality and neighbour impact.

Yes.

We confirm the route and draw to Bromley's checklist.
Alexandra Cottages is a conservation area of distinctive Victorian model-housing with strong uniform character, so external changes there are tightly assessed on materials and form. We design sympathetically and submit a full application with a Heritage Statement where the designation applies.
Usually yes outside the conservation areas — a rear dormer or L-shape within the volume allowance, confirmed by a Lawful Development Certificate. Inside the Alexandra Cottages or Penge High Street designations, roof changes need full planning. We confirm which applies to your road.
With SE20 houses around £500,000-£800,000, Penge offers some of the area's best period-home value, and a side-return or loft adds family space worth well above the build and drawing cost. The Overground link keeps demand strong, and our fixed fee keeps the professional cost predictable.

With Anerley property at around £300,000 for a flat and £500,000-£800,000 for a house, the professional drawing fee is a small fraction of the value the work adds to SE20's victorian and edwardian terraces and villas around.

We quote the drawings as one fixed price and the free site survey covers every SE20 address.

Almost always. Any structural work behind building regulations drawings in Anerley — 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 Bromley Council Building Control or an approved inspector. On SE20'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. With Anerley (SE20) property at around £300,000 for a flat and £500,000-£800,000 for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value, while our fixed drawing fee from £840 keeps the professional cost predictable. 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 SE20 homes.
