One chartered team for every drawing your project needs in Greater London: measured survey, planning, building regs, loft, extension and structural-coordinated sets — fixed-fee from £840, MCIAT-led, across all 33 boroughs.
A chartered technologist visits the property, laser-measures every room and captures photographs. Typically 60–90 minutes on site.
Drafted from the survey in Revit or AutoCAD. Scaled at 1:100 or 1:50, fully annotated and Building Control-compliant format.
Design iterations until you approve — then final planning-grade drawings with shadow studies if committee review is likely.
Site location plan (Ordnance Survey), block plan, Design & Access Statement where required, application forms, fee schedule.
We lodge the application on your behalf through the official Planning Portal with correct fees paid directly to the council.
We handle every officer query, amendment request, statutory consultation response and neighbour comment through to determination.
Five approval routes cover almost every domestic project in London. Pick the wrong one and you risk enforcement action, refusal, or paying twice. Below is the plain-English decision tree, with the typical fixed fee for the drawings each route needs.
Single-storey rear extension under 3m (semi/terrace) or 4m (detached); single-storey side extension under half the original house width; rear dormer loft under 40m³ (terrace) or 50m³ (semi/detached). No council application needed — but Article 4 Directions in 18 of 33 London boroughs can strip these rights, and PD is removed entirely on flats and listed buildings.
Optional but recommended companion to PD work. The council confirms in writing your scheme is lawful — protects against future buyers, lenders and enforcement officers. £129 council fee, 8-week determination. We submit on your behalf with the same drawing set as a Planning application.
Required when PD limits are exceeded: rear over 3m/4m, two-storey rear, wraparound side-into-rear, raised platforms over 0.3m, or new openings into a flank wall facing a neighbour. 8-week decision, £258 statutory council fee. The default route for most London extensions and loft conversions outside PD limits.
For change of use (Class MA shop-to-flat, sui generis to C3), flat conversions, HMOs, basement excavations and new dwellings. 13-week decision, £578 council fee per dwelling. Requires a Design & Access Statement plus a Planning Statement; in conservation areas add a Heritage Statement and on listed buildings a Listed Building Consent application.
Separate consent regime from planning. Full Plans submits the Building Control drawing package upfront — required for loft conversions (Part B fire), structural alterations (Part A) and any work to a party wall. Building Notice is faster and cheaper but riskier, and most London Building Control teams steer householders toward Full Plans for anything structural.
Most London householder planning submissions complete in 14–20 working days from instruction. The council then takes 8 weeks to decide on Householder applications or 13 weeks on Full Planning. Mansard, listed and conservation-area submissions add roughly one week to the drawing phase for the Heritage Statement.

Once validated by the council, a householder application takes 8 weeks for a decision. Major or full applications take 13 weeks. Our end-to-end lead time from instruction to submission is typically 3–4 weeks.
Permitted Development rights are restricted in conservation areas and removed entirely on listed buildings. You'll need full planning and, for listed buildings, Listed Building Consent too. Our Custom tier handles these — we've submitted in every central London conservation area.
Councils charge statutory planning fees directly. Current (2026) rates: householder application £258, full dwellinghouse £578, advertisement £165. These are paid to the council, not to us. We confirm the exact fee before submitting.
No one can guarantee planning approval — but our review process is built for council-ready submissions. If refused, we offer a free resubmission addressing the officer's reasons, or a 50%-rate appeal to the Planning Inspectorate.
Yes. Article 4 removes specific Permitted Development rights — common across Islington, Camden, Tower Hamlets, Waltham Forest and others for HMOs and some extensions. We check Article 4 status during the initial quote and price accordingly.
Three featured submissions across Greater London. Planning references verifiable on each council’s public portal — full case studies publishing shortly.

Watch how we prepare planning drawings for London properties — from measured survey to council submission.
Passed planning with Hackney first time on a fairly bold rear extension. The drawings were meticulous and the agent service meant I didn’t have to deal with the council at all.
