How we work on wraparound extension drawings
Nine steps from first call to approval.

Enquiry and constraints check
We check the property against conservation areas, listed status, Article 4 directions, tree preservation orders, flood zone and planning history. We choose the right route and send a fixed quote.
Measured survey
We survey the house on one datum: rooms, levels, boundaries, drains, trees and the neighbours' windows that the 45° and 25° tests depend on.
Design options
We model the house in Revit and show you options in 3D and plan, with the planning strategy and the precedents in your street.
Design frozen
You choose an option in writing. Nothing changes after this without your say.
Independent check
A second chartered technologist checks every sheet against the council's validation checklist and the policy. A senior review signs it off before anything is submitted.
Submission
We prepare the forms, certificates, fee and documents and submit through the Planning Portal.
Officer liaison
We answer the planning officer and make any amendments within five working days, at no charge until approval.
Building regulations
Technical drawings are coordinated with the structural engineer's calculations, the drainage and the planning conditions.
Approval and hand-over
Building control approval, then a next-steps pack covering the commencement notice, party wall timing and CIL.
Free redraws until approval. Every drawing set is checked independently, and the checker is never the person who drew it.

What Ealing's extensions SPD says about wraparounds
Ealing's SPD 4 - Residential extensions deals with the subject directly. In its section on conservation areas it states that rear extensions should not span the full width of the house, and that wraparound side-and-rear extensions are discouraged and usually refused.
It means a wraparound in a conservation area in Ealing starts from a presumption against, and the drawings have to answer it, not ignore it. A smaller scheme, stopping short of the full width and leaving the side gap open, is often the sensible fallback.
Outside conservation areas the same document is still the guide an officer reads first, and a wraparound that follows its principles has a stronger case. We build the drawings around the SPD's own tests.
If you are in a conservation area and want to proceed, the usual approach is to bring the extension back to a form the SPD can accept. That might be a rear extension that stops short of the full width, with a lower side element set back from the front, or a staggered plan that leaves the flank open to the street. We draw these variants side by side so you can see what you give up.
Where the existing house has a lean-to or outrigger, the design often works by replacing it with a better-proportioned structure of similar footprint. Officers respond better to a tidy, honest replacement than to a larger composite.

Ealing's heritage and policy layer
Ealing has 31 conservation areas, and Historic England lists 309 entries in the borough. Part of the borough, 6 per cent, is Green Belt.
The national rule agrees with the local one: On article 2(3) land (conservation areas etc.): no side extensions, no cladding, no rear extension of more than one storey under Class A. A wraparound includes a side arm, so it has to go through a full application in any of those areas.
The borough's policy base is older than most. Its Ealing Local Plan: Development (or Core) Strategy DPD (2012), with Development Sites DPD and Development Management DPD (December 2013) dates from 2,012, so the SPD carries more weight in practice than the policy text itself.
The borough mixes Victorian terraces near Ealing Broadway with interwar streets further out, and each conservation area has its own appraisal. We check the conservation area appraisal for your street, which usually lists the features the council wants retained.
Who lives in Ealing's houses
In Ealing 50.3 per cent of households live in a house, and 46.2 per cent own their home. Long rear gardens are where wraparound requests usually come from.
Domestic gardens cover 25.6 per cent of the land. The long plots make a deep rear arm look easy, but the side arm is where the conservation area rule bites, and in Ealing the side gap is often a deliberate part of the street's rhythm.
Ealing's Article 4 direction for houses in multiple occupation also applies in the borough, which matters if you want to let rooms. We raise it early because a larger kitchen and a rearranged first floor can tip a house into a different use.
Decisions and the prior approval record
Ealing decided 946 householder applications in its latest published year. It granted 87.2 per cent, and decided 95.3 per cent in time.
The prior approval route for larger rear extensions has a different record: 18 granted and 70 refused. Refusals outnumber approvals by a wide margin, and neighbour objection is the usual cause.
We therefore advise against building a wraparound strategy around prior approval. Our planning drawings set is the normal route here.
Even with the numbers in view, the best predictor of a decision is the planning history on your own street. We read the last few years of householder decisions near your house, note which designs were granted and which refused, and draw to the pattern.
Wraparound extension drawings in Ealing: the package
The council's householder fee is £548. A side arm on a semi means a notice to the neighbour: Line-of-junction (new wall) notice at least 1 month before work. Our drawings start at £1,195 including VAT, a second chartered technologist checks them, and we redraw at no charge if the council asks for changes.
You may want to compare rear extension drawings in Ealing or side return extension drawings in Ealing, and the borough overview is at architectural drawings in Ealing. Neighbouring councils are Brent and Hounslow.
If a wraparound is refused in a conservation area, the realistic next step is a revised scheme and not an appeal. We keep the model, redraw the narrower version at no charge, and resubmit with a note explaining how the design answers the council's comments.
Before any of that, we recommend a short pre-application conversation where the council offers one. It costs a fee, but it gives you the officer's first reading of the SPD against your own plans.
