Flat Conversion Drawings in Bexley Village DA5
Fixed-fee, MCIAT-chartered flat conversion drawings for Bexley Village (DA5) homeowners — London Borough of Bexley validation and local constraints handled from the start.
Bexley Village (DA5) sits on the River Cray at the south-eastern edge of the borough, where the historic High Street winds down past cottages and shops to the green and St John's Church. Rear and side extensions on the Victorian and Edwardian houses ringing the old core are the most common projects here, and the village's semi-rural setting on the edge of the Metropolitan Green Belt shapes how the council reads them.
The Old Bexley Conservation Area, first designated in 1971 and extended in 1987, covers the winding High Street, the green and the riverside around the old ford, protecting 18 listed buildings and the prevailing local brick. Where a DA5 property sits relative to that boundary decides whether roofline, window and front-elevation changes are permitted development or need consent.


Planning in Bexley Village (DA5): what to know before you apply
Inside the Old Bexley Conservation Area the Article 4(2) Direction means front-elevation, roof, window and boundary changes that would be permitted development elsewhere need a full householder application, and the 18 listed buildings additionally require listed-building consent. Beyond the boundary, on the Edwardian and inter-war streets toward the station, many rear and loft projects still fall within permitted development, so we check the boundary and the Green Belt edge before advising a route.
Typical Bexley Village housing stock
The conservation-area core is a tight grain of 18th- and 19th-century brick cottages, listed timber-framed houses and Victorian shopfronts along the winding High Street, giving way to Edwardian villas and inter-war semis on the rising ground toward Bexley station and Parkhill Road.

Flat Conversion Drawings for Bexley Village (DA5) homes: the package and the process
Converting a house into flats is drawn unit by unit. Each proposed flat needs its layout, its floor area, its own entrance arrangement and its amenity provision shown, along with refuse and cycle storage that meets the standards the council applies to new residential units.
The separation between units is the technical core: floors and walls detailed for fire resistance and sound insulation, a common escape route drawn and protected, and services routed without breaching the compartments. Those details go on the drawings because Building Control assesses them there, not on site.
Conversion suits buildings with the plan depth and stair position to make two workable units. A wide terrace or a large semi can usually be split without landlocking a room, while a narrow plan often cannot give both units light, access and separation at the same time.
Do I need planning permission to convert a house into flats?
Yes, always. Converting a single dwelling into two or more self-contained flats is a change from one home to several, and that subdivision is treated as development requiring a full planning application — there is no permitted development route that allows it, regardless of the property's size or whether the exterior changes at all. The application has to demonstrate that each flat meets space, layout, amenity and parking standards in its own right, not just that the building as a whole is being used sensibly.
Boroughs also weigh the loss of a family-sized house against their local housing policy, since converting a larger house into several flats reduces the stock of homes suited to families even as it adds smaller units. We take that policy context into account when advising on layout and unit numbers, rather than simply maximising the number of flats the floor area could technically support.
What sound insulation is required between flats?
Part E of the building regulations sets minimum sound insulation standards for the walls and floors separating flats, covering both airborne and impact sound. Where an existing house is subdivided, the drawings specify how the party floors and walls between units will be upgraded — additional layers, resilient bars, or a floating floor — and pre-completion sound testing is normally required before the flats can be signed off. Getting this detail right on the drawings from the outset matters, because retrofitting sound insulation after a failed test usually means taking up a finished floor or ceiling that has already been decorated.
How do you design fire escape and compartmentation for flat conversions?
Each flat needs its own independent means of escape to a place of safety, and the building has to be compartmented so that fire in one flat does not spread into another or into the shared circulation space. On a typical converted house this means fire-rated floors, walls and doors between units, and either a protected common stairway shared by the flats or separate final exits for each one, depending on the layout.
Where flats sit above ground floor level, escape routes and fire doors are designed together with the sound insulation upgrade, since the same floor and wall build-ups often need to satisfy both requirements at once.
