House Extension Drawings in Bexley
Fixed-fee, MCIAT-chartered house extension drawings for Bexley homeowners — London Borough of Bexley validation and local constraints handled from the start.
Bexley is predominantly interwar suburban London: semi-detached houses dominant across Bexleyheath, Sidcup and Welling, the historic core of Old Bexley Village with its Victorian and older housing, and riverside and post-war housing running toward Erith, Belvedere and the Thames. The generous suburban plots make rear and double-storey extensions and loft conversions the borough's most requested projects, and they frequently allow larger schemes than the tight terraces of inner London could ever accommodate.
Bexley has no borough-wide Article 4 direction affecting typical householder permitted development, so its semi-detached and detached homes often keep fuller rights than inner-London terraces — larger rear and single-storey extensions can qualify without a full application. The binding constraints instead are conservation-area control in Old Bexley Village, Danson Park and the Upton area of Bexleyheath — home to William Morris's Red House — as well as Blendon, Lamorbey and Crayford Town, and the council's expectation that extensions respect the consistent interwar building line. Thames-side and flood-zone considerations apply toward Erith and the riverside. The practical limit on a Bexleyheath or Sidcup plot is usually design and amenity policy rather than available space.
We prepare Bexley planning drawings that use the available plot fully while respecting conservation and the established suburban building line, checking permitted development limits for semi-detached and detached homes first and confirming eligibility with a Lawful Development Certificate where a project qualifies. Because the borough determines most householder applications within the statutory eight-week period once validated, we prepare submissions validation-first to keep them moving. The fee is fixed and agreed up front, drawings typically follow within about seven days, and we offer free redraws until Bexley approves — the same council-accepted drawings an architect would produce, usually at around 30% less.

Thames flood-zone considerations apply toward Erith. The borough's semis often retain fuller permitted development rights than inner-London terraces.

House Extension Drawings for Bexley homes: the package and the process
Every house extension drawings we prepare for a Bexley property is drawn to London Borough of Bexley’s validation standards and tuned to the local constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A well-drawn extension adds space and value while sailing through the council; a poorly-drawn one triggers objections and refusals. DrawingsDirect draws rear, side-return, wraparound, double-storey and basement extensions for London homes — sized to your borough's tolerances, with daylight and neighbour impact considered before the planners raise them.
Which extension types do you draw?
Every London extension is shaped by the plot, the neighbours and the borough's design guidance. We draw them all.
Rear extension
A single-storey rear extension is often permitted development within depth limits — ideal for an open-plan kitchen-diner.
Side-return
Fills the alley beside a Victorian terrace, widening the ground floor without losing garden.
Wraparound
Combines a rear and side-return extension for a transformative ground floor, usually needing planning permission.
Double-storey
Adds space above and below, subject to tighter scale and neighbour-impact scrutiny.
Basement
Creates space downward where footprint is limited, with structural and party-wall care.
Do I need planning permission for a house extension in London?
Single-storey rear extensions within permitted development limits (up to 6m for terraced/semi-detached homes under the larger-home scheme, subject to neighbour consultation) may not need a full application. Wraparounds, double-storeys and anything in a conservation area usually do. We assess your plot and recommend the right route before drawing.
| Extension | Typical route | Package | Fee from |
|---|---|---|---|
| Single-storey rear | Permitted development / householder | Planning + building regs | £1,100 |
| Side-return | Householder planning | Planning + building regs + structural | £1,600 |
| Wraparound | Householder planning | Full package + structural | £2,200 |
