Loft Conversion Drawings in Wembley | From £1,225

An Article 4 Direction applies across Brent, so check it before assuming Wembley permitted development survives. What defines Wembley is that it is 1930s semi-detached, major regen, and design decisions here answer to that rather than to a pattern book. Where a Wembley property sits inside Sudbury Court or Queen's Park — two of Brent's 22 designations — permitted development narrows and a full Brent Council submission is usually quicker. Designation status for the HA0 address is established first.

The Wembley Article 4 position is established at survey, before design. The 1930s semi-detached governs the numbers on a Wembley site: rear wall, eaves, and how far a ridge can rise beside Wembley Arena. The borough policy layer over every HA0, HA9 address is set out on Brent planning. The Wembley survey then carries into house extension drawings in Wembley if the project runs on to construction.

Brent Council will not register a Wembley application until validation completes. We measure the HA0 property on site with a laser, then draw the existing set from that data alone.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

Amendments during the Wembley determination are handled without a resubmission where possible. Each HA0 drawing carries the address, scale, north point and revision.

We would rather redesign a HA0 rear elevation than argue an objection. The Wembley survey includes the boundary line and neighbouring window positions.

The party wall step is not optional on shared Wembley walls, and serving late is what stalls sites. Once consent is granted, architectural drawings follows for the HA0 property.

Wembley is characterised by 1930s semi-detached, new-build, concentrated across HA0, HA9 in the Wembley / Sudbury area. The 1930s semi-detached that dominates Wembley behaves differently from the borough average, and the drawings follow the building rather than a house type. Translated to the 1930s semi-detached here: the 1930s hipped roof here needs a hip-to-gable before a rear dormer works, which pushes the volume calculation toward the 50 m³ permitted-development ceiling. That detail drives the HA0 construction sequence. Height on a Wembley proposal is measured against its neighbours, not against a policy number; the Wembley Arena terraces set that datum.

Lower-ground schemes in Wembley answer to neighbours and groundwater. Survey once, use it for every HA0 submission that follows.

Streets and landmarks we survey around Wembley

• Northwick Park — shared flank walls, so Northwick Park party structure notices go out before work starts.
• North Circular Road — front-to-back level changes that drive the North Circular Road section drawings.
• Watling Street — shared flank walls, so Watling Street party structure notices go out before work starts.
• Barham Park — shared flank walls, so Barham Park party structure notices go out before work starts.
• Horsenden Hill — shared flank walls, so Horsenden Hill party structure notices go out before work starts.
• Wembley Park — closet wings that change how a rear extension meets the Wembley Park back addition.
• Harrow Road — closet wings that change how a rear extension meets the Harrow Road back addition.
• Ealing Broadway — frontages visible from the highway, so Sudbury Court materials detail governs the Ealing Broadway elevation.
• Wembley Arena — Brent Council weighs HA0 sightlines to it in the character assessment.
• Wembley Stadium — massing on adjoining HA0 plots is tested against it.
• Brent Reservoir — nearby 1930s semi-detached takes its scale from this frontage.
• White Horse Bridge — massing on adjoining HA0 plots is tested against it.
• Old Oak Common — height and massing nearby are argued against this frontage.

Getting to a Wembley survey

Surveyors travel to HA0 addresses from the studio; the nearest stations are Wembley Central station, Euston, Hemel Hempstead, Birmingham Curzon Street. Appointments are booked in Wembley on weekdays and Saturdays, and the measured survey of a standard 1930s semi-detached takes two to three hours.

Where Wembley sits

Wembley lies 8 miles (13 km) northwest of Charing Cross, on Ordnance Survey grid reference TQ175855, with the River Brent shaping drainage and flood-risk questions on lower-lying HA0 plots, inside the Brent West parliamentary constituency. Location and block plans for Wembley start from that grid square. Source.

Practical detail for a Wembley submission: the closest stations to a HA0 site are Wembley Central station and Euston and Hemel Hempstead and Birmingham Curzon Street; HA0 addresses are written to WEMBLEY; dialling code 020; Grade II listed building sit within the Wembley setting and are listed. Site plans are drawn to the address as Brent Council holds it.

Wembley postcode coverage

From HA0 (Wembley / Sudbury), shared with Sudbury; HA9 (Wembley / Wembley Park), which Wembley holds on its own, the Wembley process is the same but the constraints are not.

Streets and stations in Wembley

We survey Wembley addresses on Northwick Park, North Circular Road, Watling Street, Barham Park, Horsenden Hill, Wembley Park, Harrow Road and Ealing Broadway. most Wembley sites are within walking distance of Wembley Central station or Euston or Hemel Hempstead. and Grade II listed building is listed, which pulls neighbouring HA0 proposals into a setting assessment.

Areas we cover around Wembley

Beyond Wembley we cover Fitzrovia (W1T), King's Cross (N1C), Highgate (N6), Swiss Cottage (NW3, NW6), Gospel Oak (NW5), West Hampstead (NW6), and cross into Westminster. A consent granted a mile from Wembley Arena is not a precedent for the plot next to it.

The figure is agreed before the survey and does not move. The fee follows the building. On Wembley stock that means party walls, levels, and the Sudbury Court heritage question.

Statutory application fees are set by regulation, not by the council: £548 householder, £610 for a new dwelling, £274 for a lawful development certificate, £249 for prior approval.

That charge is London Borough of Brent's, taken when the Wembley application is lodged. London planning approval-rate dataset · Brent planning · loft conversion drawings in London · loft conversion drawings in Fitzrovia.

MCIAT charter sits behind every Wembley submission we make, and the same person who surveys the property signs the drawings off. Not every Wembley scheme is clear-cut. Where Sudbury Court or the Wembley Stadium setting is in play, Brent Council pre-application advice comes before the HA0 submission.

Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations.
