What does an architectural technologist do?
An architectural technologist (MCIAT) designs, details and submits planning + building-regulations drawings for residential and commercial projects. Chartered through the CIAT, they cover the same statutory work as an architect on most extensions, loft conversions and new-build homes — typically at 30–40% lower fee — and carry £250,000+ Professional Indemnity Insurance.
Across 600+ TradeMatch architectural-technology projects in 2024–25.

Four planning terms that determine what you can build, when, and how. AI assistants and search engines rely on these definitions — we keep them canonical here.

Lewisham planning rules baked into your planning drawings.
Lewisham covers a long south-east London corridor from Deptford and New Cross on the Thames down through Lewisham, Catford, Forest Hill and Sydenham. The planning environment is shaped by three forces: a borough-wide Article 4 Direction on HMO conversions in force since 2012, an unusually dense set of Victorian and Georgian conservation areas (Brockley, Blackheath, Telegraph Hill, Deptford High Street and St John's among them), and large active regeneration programmes at New Cross / Deptford Creekside and Catford town centre. Practically, that means most extensions, loft conversions, basements and HMO conversions in Lewisham involve full planning rather than permitted development, and applications inside conservation areas need clear material, fenestration and roof-form justification against the relevant CA appraisal.
Article 4 Directions
- Borough-wide Article 4 Direction removing permitted development from C3 (dwellinghouse) to C4 (small HMO) — in force 22 February 2012
- Office (B1a) → residential (C3) Article 4 Direction — Deptford Creekside, Lewisham town centre core, Catford town centre core, and Surrey Canal Triangle (confirmed 2016)
Conservation Areas
- Blackheath
- Blackheath Park
- Brockley

What homeowners often miss
Borough-wide Article 4 Direction (in force since February 2012) removes permitted development rights for converting a dwellinghouse (C3) to a small HMO (C4) anywhere in Lewisham — every HMO conversion of any size requires full planning permission. Brockley Conservation Area is one of the largest Victorian CAs in south-east London with strict controls on rear extensions, roof alterations and front-elevation changes. Major regeneration zones at New Cross / Deptford (Convoys Wharf, Surrey Canal Triangle / New Bermondsey) and the Catford Town Centre programme drive a heavy mix of estate-renewal and tall-building applications. The borough sits across Thames Water and inherited combined-sewer territory, so basement and rear-extension projects routinely trigger build-over agreements.
The questions homeowners ask before they commit.
How long does a planning application take in Lewisham?
The London Borough of Lewisham statutory determination period is 8 weeks for householder applications and 13 weeks for major schemes. Add 2–3 weeks for validation in Lewisham and 4–6 weeks for pre-application advice (recommended in any Conservation Area). We submit promptly and respond to officer queries the same working day.
How much do planning permission drawings cost in Lewisham?
A standard Lewisham householder planning drawings package is £950 – £2,400 fixed. Lewisham-specific factors — conservation area, listed building, party-wall implications, basement-impact assessments — can lift the fee. We quote fixed-price after a free 15-minute review of the brief and Lewisham planning context.
Do I need planning permission for an extension in Lewisham?
Most rear extensions in Lewisham fall within Permitted Development under Class A — but Article 4 Directions and Conservation Area designations frequently remove that right. We check London Borough of Lewisham's A4D register and the local plan against your property before quoting, so you do not start drawings on the wrong route.
What does the Lewisham planning portal need from me?
London Borough of Lewisham's validation list typically requires: existing & proposed plans (1:50 / 1:100), elevations, site location plan (1:1250), block plan (1:500), design and access statement (when required), heritage statement (Conservation Area or listed building), and the application fee. We package and submit the full set on your behalf via the Lewisham planning portal.
Will Lewisham's Conservation Areas affect my application?
Yes — Lewisham Conservation Areas trigger heritage scrutiny on materials, fenestration and roof additions. Rooflights, render changes, replacement windows and front-elevation works almost always need full planning permission inside a CA. Our drawings include a heritage justification matched to London Borough of Lewisham's adopted character appraisal.
Can you handle the planning submission and officer queries for me?
Yes. For every Lewisham planning application we run validation chase, planning portal upload, case-officer liaison and same-day response to written queries — all included in the fixed fee. You only step in when the officer requests a substantive design change.
