In West Ealing (W13) we draw up planning and building-control packages for rear kitchen extensions, loft conversions and refurbishments on the district's Edwardian terraces and villas.

The St Stephen's and Ealing Green conservation areas mean side extensions and roof changes get closer scrutiny, so we check whether your address sits inside the boundary before choosing between permitted development and a full application.

Planning in West Ealing (W13): what to know before you apply

There is no Article 4 direction on the W13 conservation areas, but conservation-area status still removes some permitted-development rights and adds design scrutiny. Homes outside the boundary often keep full rear-extension and loft PD allowances, which we confirm case by case.

Typical West Ealing housing stock

West Ealing is dominated by late-Victorian and Edwardian terraces and semi-detached villas laid out around Northfield Avenue and the St Stephen's streets, many with generous rear gardens suited to extensions.

Structural Drawings for West Ealing (W13) homes: the package and the process

Structural sheets are issued to be built from. Beam and lintel schedules give size, grade and bearing; connection details show how each element meets the next; and padstones, straps and restraint are drawn at the junctions rather than noted in general terms. Calculations are submitted alongside so Building Control can check the design rather than take it on trust.

Coordination with the architectural set is where the value is. A beam that is right in isolation but sits below the approved ceiling line, or a column that lands in a doorway, is a site problem that costs more to fix than it did to draw. We resolve those clashes in the drawing stage.

The existing structure sets the design. A terrace transfers load through party walls that are shared and often unrecorded, a semi through one; and floor construction — timber, concrete, or a mix from earlier alterations — changes how a new opening is supported and what has to be exposed to find out.

Do I need structural calculations to remove a load-bearing wall in London?

If a wall carries any load from above — a floor, a roof, another wall, or a chimney breast — you need a structural calculation before it can be removed, and Building Control will ask for it as part of a Full Plans or Building Notice submission. This covers the great majority of kitchen-diner knock-throughs in London terraces and semis, where the wall between the kitchen and the rear reception room is almost always load-bearing. A calculation confirms the size and type of steel beam needed to replace the wall's support, the padstones or pier that carry the beam's weight down to the foundations, and the temporary propping needed while the work is carried out. If the wall shares a boundary or the new beam bears on a party wall, the Party Wall etc. Act 1996 will also apply and needs to be dealt with separately from the calculation itself.

How steel beam sizing works

A structural engineer calculates the loads bearing down on a wall from the floors, roof and any walls above it, then sizes a steel beam (RSJ) — its depth, width and steel grade — so it can safely carry that load across the required span without excessive deflection. The calculation also fixes the bearing length at each end, the padstones or steel plates that spread the load into the surrounding masonry, and whether the existing foundations need strengthening to take the extra point loads. Because we coordinate the calculation with the architectural drawing set, the exact beam size, orientation and position shown on your plans is the one the calculation specifies — so your builder can order the correct steel first time, and Building Control sees a consistent set of drawings rather than two documents that disagree.

How much do structural drawings cost in London?

Structural drawings and calculations start from £745 for a single beam or wall removal, agreed as a fixed fee before work begins. The price depends on the number of beams or walls involved, whether foundations need designing from scratch (as with a rear or side extension), whether existing floor and roof structures need checking for extra loading (as with most loft conversions), and whether retaining or underpinning calculations are required, as they are for basement conversions. Where structural work is part of a wider extension or loft project, the all-inclusive package from £1,845 includes the calculation; with planning or building regulations drawings alone it is this separate fee.

FAQ

Structural Drawings in West Ealing W13 — FAQs

Do I need a structural engineer to remove a wall in my London home?+
Yes, if the wall is load-bearing — which most internal walls between a kitchen and reception room are. A named, insured engineer we work with prepares the calculation and we coordinate it with your drawings, so you do not need to find and brief an engineer yourself.
How long do structural calculations take?+
Structural drawings are typically ready within about 7 days of instruction, in line with the rest of our drawing packages, and are produced alongside your architectural and building regulations drawings so everything is issued together.
Will the steel beam on my drawings match what my builder orders?+
Yes — because we produce the architectural drawings and coordinate the structural calculation together, the beam size, position and bearings shown on your plans are the ones the calculation specifies, so there is nothing for your builder to reconcile on site.
Can you produce structural drawings without handling my full planning application?+
Yes, a standalone structural calculation is available if you already have architectural drawings and just need a wall or beam calculated and signed off for Building Control.
Do structural calculations need to be submitted to Building Control?+
Yes — a structural calculation is a required part of a Full Plans or Building Notice submission wherever a load-bearing wall, beam or foundation is involved, and Building Control will not approve the work without one.
Do I need planning permission for a rear extension in Ealing?+
Many Ealing semis and terraces keep permitted development rights for a single-storey rear extension, so a full application isn't always needed. In a conservation area such as Bedford Park or Pitshanger, dormers and other roof enlargements, side extensions, rear extensions over one storey and cladding are not permitted development. The borough-wide Article 4 direction on HMO conversions is a separate change-of-use control. We check your address against the designations first and, where it qualifies, 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. In a conservation area dormers and other roof enlargements, side extensions, rear extensions over one storey and cladding are not permitted development, so we design to the area's Arts-and-Crafts character and prepare a full householder application with the elevations and materials the council expects.
How long does Ealing Council take to decide a householder application?+
Ealing has eight weeks from the day after it receives a valid application, unless a longer period is agreed in writing. We follow the council's validation checklist: correctly scaled existing and proposed plans, elevations and a location plan.
Can you help with a loft conversion on a 1930s Ealing semi?+
Yes. Ealing's Metro-land semis in Perivale, Greenford and Northolt suit hip-to-gable and dormer loft conversions, which frequently qualify as permitted development on semi-detached homes within the volume limits. We confirm eligibility against those limits and any Article 4 or conservation constraint, then produce the planning and building-regulations drawings.
How much do planning drawings cost in Ealing?+
We work to a fixed fee agreed before we start, taken from our published price list, with free redraws until Ealing grants approval. The exact figure depends on the project — a single-storey rear extension differs from a double-storey or a loft — so we quote once we understand your scheme rather than on an open-ended hourly basis.
