Basement Conversion Drawings in Greenford UB6
Fixed-fee, MCIAT-chartered basement conversion drawings for Greenford (UB6) homeowners — London Borough of Ealing validation and local constraints handled from the start.
Greenford (UB6) is classic outer-west-London Metro-land: broad avenues of interwar semis with deep gardens, ideal for rear and wraparound kitchen extensions, loft conversions with rear dormers, and garage-to-room conversions. Most householder projects here fall squarely within permitted development or a straightforward Ealing Council householder application.
The one sensitivity is the Canalside conservation area on the neighbourhood's north-west flank near the Grand Union, where materials and rear massing get closer scrutiny. We prepare drawings that hold the interwar building line and gap-to-boundary rhythm Ealing's officers expect, and flag any canal-edge or former-industrial plot early so ground and drainage issues are designed out.
Planning in Greenford (UB6): what to know before you apply
No published householder Article 4 direction in Greenford, so most extensions and lofts run under permitted development or a standard Ealing householder application. Properties bordering the Canalside conservation area lose some permitted-development rights, and rear/side extension depths are assessed against the neighbouring semis' building line.
Typical Greenford housing stock
Greenford is dominated by 1920s-30s bay-fronted semis and short terraces laid out along wide suburban avenues, many with generous rear gardens and original hipped roofs. Nearer the Grand Union Canal and the old Rockware/Lyon works, plots give way to former industrial land and later flat-roofed infill.

Basement Conversion Drawings for Greenford (UB6) homes: the package and the process
Every basement conversion drawings we prepare for an Greenford property is drawn to London Borough of Ealing’s validation standards and tuned to the UB6 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A basement conversion is one of the few ways to add genuine living space to a London home without touching the footprint above ground, but the drawings have to earn their keep in two very different disciplines at once. Converting an existing cellar into a habitable room is largely a building-regulations exercise, while digging out a new basement or lowering an existing floor is a structural undertaking that usually brings planning permission, underpinning design and neighbour consultation into the project as well.
DrawingsDirect prepares both types of basement drawing set for London homes — fit-out packages for existing cellars and full structural packages for new-dig or lowered basements — with waterproofing, means of escape, ventilation and Party Wall coordination built in from the first survey. As a chartered architectural technologist practice, we produce the structural design in-house rather than outsourcing it, so the drawings and the calculations arrive together, checked against each other, at a fixed fee.
Do I need planning permission for a basement conversion in London?
An internal conversion of an existing cellar — new floor, insulation, a habitable layout — often does not need planning permission, because the works sit entirely within the existing structure and do not change its external appearance. Digging out a new basement, lowering an existing floor to gain headroom, or enlarging the footprint under a garden usually does, particularly where excavation extends beyond the existing building line. Any external alteration needed to serve the basement — a front light well, a sunken external staircase, or altering the pavement or front garden — is also likely to need planning permission in its own right, even when the basement works themselves would not. In a conservation area, a front light well tends to draw closer scrutiny than the same feature elsewhere, since it changes the street-facing elevation and the pavement it sits within — one more reason we assess the whole scheme, not just the room below ground, before recommending a route.
Cellar conversion or new dig-out — which route fits your property?
The two starting points lead to very different drawing sets. A cellar conversion works with a void that already exists: the drawings focus on damp-proofing, insulation, headroom, natural or borrowed light, means of escape and a compliant layout, coordinated with building regulations rather than planning.
A new dig-out or floor-lowering project starts from a structural decision — how the existing foundations will be underpinned to allow excavation beneath them — and the drawings and structural calculations are produced together from the outset, since the sequence of underpinning, temporary works and waterproofing has to be engineered before a builder can safely start.
| Route | Typical scope | Planning position | Fee from |
|---|---|---|---|
| Existing cellar conversion | Fit-out of an existing void, no excavation | Usually building regulations only | £2,400 |
| Floor lowering / partial dig-out | Increases headroom within the existing footprint | Often needs planning permission | £3,200 |
| New-build basement or light well extension | New basement area beyond the existing footprint | Full planning plus Party Wall Act | £3,850 |
