Building regulations drawings in Ealing
Building regulations drawings for an Ealing home start at £845 including VAT. They turn an agreed design into the construction sheets that building control checks. Ealing splits almost evenly between houses and flats, so we draw both the extension on a terrace and the refurbishment inside a block.

Ealing's housing split and its extension guidance
50.3 per cent of Ealing's 133,659 households live in a house or bungalow, and 46.2 per cent are owner-occupied. Roughly half the borough therefore lives in flats, and the other half in houses that families extend.
For houses, the council's SPD 4 - Residential extensions sets the planning expectations: how far an extension projects, how it relates to the neighbours and what it looks like from the street. It sits under a development plan whose core strategy dates from 2,012. Building Regulations do not read that guidance. They ask whether the structure stands up, keeps warm, resists fire and drains.
Heritage adds a layer in places. Ealing publishes 31 conservation areas and Historic England lists 309 buildings, with 6 at Grade I and 18 at Grade II*. If your house is among them, tell us first, because the energy measures may need a reasoned approach.

Building regulations drawings in Ealing, step by step
We begin with a measured survey, then draw foundations and floor plans, the roof, sections and the junctions that tend to fail: old to new walls, door thresholds, roof edges. A specification lists products and workmanship standards by name.
The set is coordinated with your engineer, or with our structural calculations in Ealing if you have none. Where the design still needs consent, the earlier step is planning drawings in Ealing, and if permitted development may apply, a Lawful Development Certificate in Ealing settles it first.
A second chartered technologist checks every sheet before issue, and if the examiner asks for revisions we make them at no charge.
Choosing the route and finishing cleanly
A building notice is the quick route, but it carries a limit: it ceases after 3 years if work has not started. We still prefer full plans, because a decided set is a fixed instruction for your builder.
Notice does not end with the start. Notify completion within 5 days of completing the work. We hand your builder a short list of the notices and inspections so that the completion certificate is not delayed.
Ealing decided 946 householder planning applications in its latest published year and granted 87.2 per cent, with 95.3 per cent decided in time. Those are planning figures and describe the past.
Terraces, conversions and flats in Ealing
Ealing projects fall broadly into three groups. The first is a rear or side extension to a terraced or semi-detached house. The second is a loft conversion, where Part B and Part K govern escape and stairs. The third is the conversion of a larger house into flats, where sound, fire and drainage drive the drawings.
For an extension, the sheets show the foundation, wall build-up, beam and roof, together with the junction to the old house and the drainage. For a loft, they show the new floor, the stair with its headroom and going, the escape window or protected route, and insulation to the new roof.
For a conversion, they show the separating floors and walls, the entrance and escape arrangements for each flat, the services to each and the refuse and cycle areas that planning has asked for. These are heavier sets, and they benefit from an early conversation with building control.
We also record the existing drainage, because older houses often have a combined system and shared runs. Where a new bathroom or kitchen is added, the sheets show a connection that works, and mark any inspection chamber that must be opened.
If you are unsure which of the three groups your project falls into, send us the address and a short description, and we will tell you what the set will contain.

Questions
Does an Ealing flat need building regulations drawings?
Yes, for structural change, altered layouts, new drainage or ventilation, and fire separation. The freeholder may also ask for the sheets.
Is a building notice enough for an Ealing extension?
It is allowed, but it lapses after 3 years if work has not started, and checking happens on site. We usually advise full plans.
What notices must I give at the end of the work?
Notify completion within 5 days of completing the work. We give your builder the list at handover.
How much do building regulations drawings cost in Ealing?
From £845 including VAT, fixed up front. Building control fees are separate.
