For Southall property owners: MCIAT chartered loft conversion plans. The authority for Southall is Ealing Council; the policy is the Ealing Local Plan; the address sits in UB1, UB2.
Loft Conversion Drawings for a UB1, UB2 address are measured Southall plans, sections and elevations turning a roof space into habitable UB1, UB2 rooms. The determining authority in Southall is Ealing Council, working to the Ealing Local Plan, and on the edwardian terraces they prove 2.2 m head height for Southall and hold the 40 m³ or 50 m³ volume unless Ealing Council grants consent.
An Article 4 Direction applies across Ealing, so check it before assuming Southall permitted development survives. The prevailing character of Southall — Edwardian terraces, post-war estates — sets what Ealing Council will accept near Southall Broadway and what it will resist. Ealing carries 30 conservation areas; if the UB1 address falls in Bedford Park or Acton Green, expect the permitted-development route to close and a full Ealing Council application to be the faster answer. The designation map is read street by street in Southall.
Before drawing anything for Southall, we check Article 4 directions against the UB1 boundary. On Southall plots the original rear wall and the Southall Broadway ridge line set the envelope. The borough policy layer over every UB1, UB2 address is set out on Ealing planning. The Southall survey then carries into building regulations drawings in Southall if the project runs on to construction.



The UB1, UB2 bottleneck is validation. London Borough of Ealing needs one to two weeks, and a missing drawing resets it. The Southall survey comes first, because a proposal drawn on wrong existing plans fails validation later.
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.
An officer report on the UB1 case is written after the consultation closes. Every Southall submission leaves here as a PDF set at the scales Ealing Council requires.
The Southall consultation period is where a weak scheme is exposed. Party wall positions on a Southall terrace are located during the survey.
Budget notice time on any Southall job touching a shared wall. Once consent is granted, house extension drawings follows for the UB1 property.
Southall is characterised by edwardian terraces, post-war flats, concentrated across UB1, UB2 in the Southall North area. Southall is not uniform, but the edwardian terraces recurs often enough across UB1, UB2 that the structural pattern is predictable once measured. On UB1 plots specifically, edwardian roofs run deeper front-to-back, so an L-shaped dormer over the back addition usually yields a second bedroom as well as the shower room. That detail drives the UB1 construction sequence. Height on a Southall proposal is measured against its neighbours, not against a policy number; the Southall Broadway terraces set that datum.
Going down in Southall is assessed on ordinary grounds — UB1 ground conditions and drainage do more to shape the scheme than policy does. A Southall survey done once feeds architectural drawings for UB1 properties and planning permission later.
For a UB1, UB2 address the deliverables are fixed, not open-ended.
Surveyors travel to UB1 addresses from the studio; the nearest stations are Southall, Swansea, Reading, Oxford. Appointments are booked in Southall on weekdays and Saturdays, and the measured survey of a standard edwardian terraces takes two to three hours.
on Ordnance Survey grid reference TQ125805, with the Grand Union Canal shaping drainage and flood-risk questions on lower-lying UB1 plots, inside the Ealing Southall parliamentary constituency. We draw the Southall location and block plans from that reference, which is what Ealing Council validates against. Source.
Practical detail for a Southall submission: access is via Southall and Swansea and Reading and Oxford; addresses are written to SOUTHALL; dialling code 020; heritage assets close by include Grade II* Tudor style architecture. Site plans are drawn to the address as Ealing Council holds it.
Our Southall coverage takes in UB1 (Southall North), which Southall holds on its own; UB2 (Southall South), which Southall holds on its own.
High Street, Stewarts Lane, Uxbridge Road and Norwood Green are typical of the Southall streets we draw. most Southall sites are within walking distance of Southall or Swansea or Reading. and Grade II* Tudor style architecture is listed, which pulls neighbouring UB1 proposals into a setting assessment.
Work spreads across Hanworth (TW13), Turnham Green (W4), Uxbridge (UB8), Ruislip (HA4), Northwood (HA6), Hayes (UB3, UB4) as well as Southall itself.

What moves the number on a Southall job is the edwardian terraces itself — party walls, level changes, and whether Bedford Park pulls a heritage statement into scope.
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.
The statutory element is payable to London Borough of Ealing, not to us. London planning approval-rate dataset · Ealing planning · our London loft conversion drawings service · loft conversion drawings in Hanworth.
An MCIAT chartered technologist owns the Southall project from survey to decision. Borderline Southall sites (anything overlooking Southall Broadway, anything with a Bedford Park frontage) go to Ealing Council for pre-application advice before we submit.
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. Confirm your local authority at gov.uk and submission requirements on the Planning Portal. Studio: 71–75 Shelton Street, London WC2H 9JQ.
Give us the UB1 postcode and we will tell you which route applies. This Southall page was reviewed in August 2026.
Sometimes yes, sometimes no — the Southall address decides it. An Article 4 Direction applies across Ealing, so check it before assuming Southall permitted development survives. A £274 certificate records the answer for a future buyer.
Conservation status in Southall typically means Bedford Park, one of 30 across Ealing.
Southall is dominated by edwardian terraces, post-war flats. The UB1 district (Southall North) covers most addresses we survey, and the edwardian terraces sets the structural approach long before the planning route does. Every survey is laser-measured.
We cover Hanworth, the wider Ealing area and across into Brent. The reason Southall has a separate page is that a consent granted a mile off is no precedent for a UB1 street.
