Cranford sits on the western edge of Hounslow near the Heathrow boundary, and its interwar and post-war housing makes it a straightforward, permitted-development-friendly area for family projects: rear extensions, side infills and loft conversions on the semis along The Avenue, Berkeley Avenue and Chaucer Avenue, where back gardens give plenty of room to extend.

Away from the Cranford Village and Cranford Park conservation areas most schemes proceed under permitted development, but we design to Hounslow Council's standard throughout — factoring in aircraft-noise glazing and ventilation near Heathrow, party wall coordination on semi-detached plots, and flood-aware drainage on the lower ground close to the River Crane.

Planning in Cranford (TW5): what to know before you apply

No published householder Article 4 direction applies in Cranford, so most extensions and lofts fall under permitted development. The Cranford Village and Cranford Park conservation areas, Heathrow aircraft-noise designations and localised flood risk near the River Crane are the constraints to design around.

Typical Cranford housing stock

Cranford is a suburban district on the Heathrow fringe, made up of 1930s semis and post-war housing on roads like The Avenue and Berkeley Avenue, with generous back gardens. The stock suits single-storey rear extensions, side infills and hip-to-gable loft conversions carried out under permitted development.

New Build Drawings for Cranford (TW5) homes: the package and the process

Every new build drawings we prepare for an Cranford property is drawn to London Borough of Hounslow’s validation standards and tuned to the TW5 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Designing a new dwelling on an infill or backland plot in London is a longer and more technically demanding journey than an extension or loft conversion — it involves establishing whether the plot can support a new home at all, securing full planning permission against a borough's density, design and amenity policies, and then producing a building regulations and structural package detailed enough to actually build from. DrawingsDirect delivers all of this as one coordinated service: feasibility, full planning drawings, building regulations drawings and structural calculations, produced in-house rather than passed between separate architects, engineers and drafters who each need briefing and coordinating separately.

London infill and backland sites bring specific challenges that a straightforward extension does not: the impact of a new dwelling on neighbouring daylight and sunlight, privacy and overlooking, the character and density of the surrounding streetscape, and access, parking and refuse arrangements for a new independent home. Getting an early, honest read on these issues — before a full application is drawn and submitted — is often the difference between a scheme that is approved and one that is refused and has to be reworked. We assess feasibility and, where useful, prepare pre-application advice before committing to a full drawing set.

Is my plot suitable for a new build in London?

A feasibility assessment looks at plot size and shape, access, existing boundary conditions, relevant planning policy for the borough, and the likely impact of a new dwelling on neighbouring properties before any design work begins. Infill plots — a gap between existing buildings on a street — and backland plots — a garden or yard site behind existing houses, reached by a shared access — each raise different issues: infill schemes are usually judged on how well they match the scale, spacing and character of the street, while backland schemes are judged heavily on overlooking, garden loss for neighbours, and whether the access arrangement is acceptable. A feasibility study gives an honest view of whether a scheme is likely to succeed before you commit to full drawings.

What does pre-application advice add to a new build project?

Pre-application advice is a formal, paid process most London boroughs offer, where planning officers give written feedback on a proposed scheme before a full application is submitted. For a new build — where the principle of development itself is often the main issue, not just the design details — this feedback can be invaluable: it surfaces concerns around density, massing, daylight and sunlight or heritage context early enough to be addressed in the drawings, rather than discovered for the first time as a refusal reason months into a full application. We prepare and submit pre-application enquiries as part of the new build service where it is likely to strengthen the eventual planning application.

FAQ

New Build Drawings in Cranford TW5 — FAQs

How much do new build drawings cost in London?+
New build drawings start from £2,500 for feasibility and a full planning drawing set on a straightforward infill or backland plot, with building regulations and structural drawings quoted separately once the planning design is agreed.
Can any garden or backland plot be built on in London?+
Not necessarily — backland and garden plots are assessed on access, overlooking, loss of garden amenity for neighbours and borough policy, and a feasibility assessment gives an honest early view of whether a scheme is likely to be supported.
Do I need pre-application advice before a full new build application?+
It is not mandatory, but for a new dwelling — where the principle of development is often the main issue — pre-application advice can surface concerns early enough to address them in the design, reducing the risk of refusal.
Do you handle building regulations and structural drawings for a new build, or only planning?+
Both — the full new build service covers planning, building regulations and structural drawings from one in-house team, so the design stays consistent from feasibility through to construction-ready drawings.
How long does a new build project take from feasibility to planning permission?+
This varies with site complexity and whether pre-application advice is sought, but a full planning application is determined within the statutory period the borough applies to the application type, once submitted via the Planning Portal.
Do I need planning permission for an extension in Hounslow?+
It depends on the area. The interwar semis of Osterley, Hounslow and Feltham often retain permitted development rights for rear extensions and lofts, while the Chiswick terraces and Bedford Park sit within conservation areas where those rights are removed. We check your address against the designations first and can confirm permitted development with a Lawful Development Certificate.
What extra control applies in Bedford Park?+
Bedford Park is one of West London's most tightly controlled conservation areas, with detailed control over materials, rooflines, windows and front elevations. A standard permitted-development dormer or cladding change usually won't apply; instead we design to the area's Arts-and-Crafts character and prepare a full householder application with the elevations and materials the council expects.
Does Heathrow or the river affect my Hounslow project?+
They can. Toward the west of the borough, aircraft-noise considerations near Heathrow may influence habitable-room and glazing design, and along the Thames at Strand-on-the-Green and Isleworth the flood zone must be addressed. We evidence these considerations within the application where they apply so the council can validate and approve without repeated revisions.
How long does Hounslow Council take to decide?+
Hounslow determines most householder applications within the statutory eight-week period once validated; Bedford Park, conservation and riverside cases can involve additional consultation. We prepare submissions to the council's validation checklist to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Hounslow?+
We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Hounslow approves. A suburban Osterley extension and a Bedford Park application differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
