Chartered architectural drawings for planning permission in Lambeth — from Clapham terraces to Brixton flat conversions, designed around Lambeth Council's policies and revised free until you get a decision.
Lambeth runs north to south through some of London's most varied streetscapes: stucco terraces near the river, tall Victorian houses around Clapham Common, tight terraced grids in Brixton and Stockwell, and leafy Edwardian streets down through Streatham and West Norwood. Lambeth Council assesses proposals against its Local Plan and detailed residential design guidance, and case officers here pay close attention to rear-garden impact, roofline consistency and the standard of accommodation in conversions.
Conservation areas cover a meaningful share of the borough — including Clapham and Stockwell Park — and many inner-London conservation areas carry Article 4 directions removing permitted development rights, so verify what applies to your address before relying on permitted development. Flats, which make up a large slice of Lambeth's housing, never have permitted development rights at all.
Our approach is to settle those questions before drawing begins. We check your address against Lambeth's constraints, review how the council has decided comparable applications nearby, and then design a scheme the case officer can approve without a fight. If Lambeth asks for amendments, we make them free of charge until you have a decision.
The numbers below are pulled live from official planning records for Lambeth, so you are looking at how the council genuinely decides — not a marketing claim. Two things move the odds in your favour anywhere in inner London: a design that respects the policies officers must apply, and a drawing pack that is accurate, complete and easy to assess. Both are in our control, which is why we design against Lambeth's guidance from the first line and keep revising free until the council issues its decision.

From Clapham side returns to Brixton flat splits, these are the applications Lambeth homeowners and landlords bring us most often.
The classic Lambeth kitchen-diner across Clapham, Brixton and Streatham terraces — depth, height and glazing tuned to the council's amenity tests.
Splitting Victorian houses into flats with layouts that meet Lambeth's space and outlook standards, plus the floor-area schedules officers check.
Rear dormers and hip-to-gable conversions drawn to respect terrace rooflines — the first thing Lambeth officers look at in conservation areas.
Floor plans for licensed HMOs across Lambeth, drawn to licensing space standards and coordinated with any planning requirements.
Lightwell and basement drawings prepared with the structural and construction-method information Lambeth expects for excavation schemes.
Combined side-and-rear schemes that maximise ground-floor space while staying inside Lambeth's design guidance.

You need planning permission in Lambeth for flat conversions, most extensions beyond permitted development limits, basements, and most external changes in conservation areas — where Article 4 directions often remove permitted development rights. A full application is likely if:
We draw for the whole borough — riverside terraces, Brixton grids, Streatham semis — with designs shaped by how Lambeth's officers actually decide, and free revisions until they say yes.
Four fixed steps from enquiry to decision, with Lambeth's validation checklist covered at every stage.
We screen your address for conservation areas, Article 4 directions and Lambeth's recent decisions on similar projects before you commit to anything.
Accurate existing floor plans and elevations — the baseline Lambeth officers measure every proposal against.
Proposed drawings at 1:50 or 1:100 with a 1:1250 location plan, designed to Lambeth's residential guidance and annotated for easy assessment.
We submit via the Planning Portal, answer validation and officer queries, and revise free until Lambeth issues its decision.
Lambeth's Victorian terraces were built in long speculative runs, which is good news for extenders: the council has decided hundreds of near-identical schemes, so precedent on your street usually exists and we use it. Side returns and full-width rear extensions are well-trodden paths in Clapham, Brixton and Stockwell, and a design that mirrors an approved neighbouring scheme — done properly, not copied blindly — starts from a strong position with the case officer.
Further south, Streatham and West Norwood bring wider Edwardian plots and more generous permitted development headroom, while the borough's mansion blocks and converted houses mean a large share of Lambeth clients are flat owners, whose projects always need a full application regardless of size. Each of these situations calls for a different drawing strategy, and choosing it correctly at the start is worth more than any amount of negotiation later.
Whatever the property type, the deliverable is the same: a complete, correctly scaled pack that validates first time and gives Lambeth's officers every reason to approve — with free revisions until they do.
Lambeth Council decides householder applications for Lambeth, and its recent record and the permitted-development limits that apply here set out below give Clapham homeowners a realistic starting point before any drawing begins.
| Measure | Figure for Lambeth |
|---|---|
| Lambeth Council householder approval rate | 89% |
| England-wide householder benchmark | 87% |
| Loft dormer permitted-development limit (Class B) | 40m³ terrace / 50m³ semi or detached |
| Single-storey rear extension depth (Class A) | 3m terrace / 4m detached |
| Dominant housing era | Georgian (1714–1837), Victorian (1837–1901) and Edwardian (1901–1910) |
| Statutory decision period | 8 weeks |
| Conservation / Article 4 status | Article 4 direction in force; PD removed in Clapham Old Town, Stockwell Park and Angell Town |
Lambeth runs 2 points above the national average. Approval rate: MHCLG householder planning statistics for Lambeth Council; permitted-development limits: GPDO 2015, Schedule 2, Part 1 (Classes A–B).
The statutory target is eight weeks for householder and most full applications, thirteen for major schemes, counted from validation. Lambeth returns incomplete packs unvalidated, which silently adds weeks. We deliver drawings matching the council's validation list so the clock starts first time, then manage the case officer relationship to a decision.
Often not, if your house is outside a conservation area and the extension stays within permitted development limits — though a lawful development certificate is strongly advised. In Lambeth conservation areas such as Clapham, Article 4 directions may remove those rights, making a full application necessary. We confirm your position before drawing.
Conversion to flats always needs planning permission. Lambeth assesses the standard of accommodation — unit sizes, outlook, amenity space — alongside the mix of homes in the area. Success depends on layouts that genuinely meet the standards, which is exactly what our conversion drawings are annotated to demonstrate.
Existing and proposed floor plans and elevations at 1:50 or 1:100, a site location plan at 1:1250 with a red-line boundary, and a block plan. Conversions and conservation-area schemes usually need sections and a design and access statement too. Our Lambeth packs cover the full validation checklist.
Lambeth has designated conservation areas across the borough, including Clapham and Stockwell Park, and several carry Article 4 directions. We check your exact address against Lambeth's conservation-area maps and Article 4 schedules as part of the free approval check, so you know the rules before spending anything on design.
We revise the drawings against the refusal reasons and resubmit free of charge. Lambeth refusals cite specific policies — typically amenity impact, roofline or standard of accommodation — and most are resolved with focused amendments. Designing to policy from day one is how we keep refusals rare in the first place.
