QUICK ANSWER
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.

PLANNING IN WANDSWORTH
Wandsworth-specific planning rules built into the fee.
Wandsworth blends Victorian villa territory (Wandsworth Common, Nightingale Lane, West Putney, East Putney, Magdalen Park) with one of London's most active modern development clusters — Nine Elms, Battersea Power Station and the SW8/SW11 riverfront. The borough has 46 designated Conservation Areas, including the historic estates of Dover House, Heaver, Latchmere, Shaftesbury Park and Totterdown Fields, each protected by Article 4(2) Directions on minor exterior alterations. Two borough-wide Article 4 Directions remove Permitted Development rights for Class E → C3 (in force 29 July 2022) and B1(a) office → C3 conversions, and the Local Plan 2023-2038 (adopted 19 July 2023, Partial Review March 2026) tightens basement-impact, daylight/sunlight and tall-building scrutiny. Pre-application advice is essential on any Conservation Area frontage and on any sub-grade scheme.
Article 4 Directions
- Borough-wide Article 4 Direction — Class E (commercial/business/service) → C3 (dwellinghouses); modified Direction in force 29 July 2022; covers ~60 named centres, parades and CAZ-edge areas
- Borough-wide Article 4 Direction — B1(a) office → C3 (dwellinghouses); removes PD rights for office-to-residential conversions
- Borough-wide Article 4 Direction — Public Houses and Bars; removes PD rights for change of use / demolition
- Wandsworth Common Conservation Area — Article 4(2) Direction on minor exterior alterations to single dwellings
- Putney Lower Common Conservation Area (15-36 Commondale) — Article 4 Direction on minor alterations
- Magdalen Park Conservation Area — Article 4 Direction adopted 31 August 2023
- Dover House Estate Conservation Area — Article 4 Direction on exterior works
- Heaver Estate Conservation Area (Tooting/Balham) — Article 4 Direction

What homeowners often miss
Wandsworth has 46 designated Conservation Areas — among the highest counts in inner south-west London — and operates a borough-wide Article 4 Direction (modified, in force 29 July 2022) removing Permitted Development rights for Class E → C3 conversions across roughly 60 named centres and parades. A second borough-wide A4D removes PD on B1(a) office → C3 conversions, and Article 4(2) Directions across Wandsworth Common, Putney Lower Common, Magdalen Park (adopted August 2023) and the historic estates (Dover House, Heaver, Latchmere, Shaftesbury Park, Totterdown Fields, Roehampton Village) remove PD on minor exterior alterations to single dwellings. Local Plan basement policy (LP24, 2023-2038 plan) requires a Basement Impact Assessment and Construction Method Statement for sub-grade development, and the Nine Elms / Battersea Power Station Opportunity Area imposes a tall-building, daylight/sunlight and townscape regime that materially shapes any architectural-tech work in SW8 and northern SW11.
FAQ
The questions homeowners ask before they commit.
Do I need planning permission for a loft conversion in Wandsworth?
Most loft conversions in Wandsworth fall within Permitted Development — but Article 4 Directions in conservation areas often remove that right. We assess your property’s status before quoting, and if planning permission is required we deliver the drawings + submission as a fixed fee.
How much do planning drawings cost in Wandsworth?
A standard householder planning application in Wandsworth runs £950 – £2,400 for the drawings package. Wandsworth-specific factors — conservation area, listed building, party-wall implications — can lift the fee. We quote fixed-price after a free 15-minute review of the brief.
How long does a Wandsworth planning application take?
The London Borough of Wandsworth statutory determination period is 8 weeks for householder applications and 13 weeks for major schemes. Pre-application advice (recommended in conservation areas) takes 4–6 weeks. We submit promptly and respond to officer queries the same working day.
What’s the difference between planning permission and building regulations drawings?
Planning is about whether you can build it (siting, scale, impact on neighbours, conservation). Building regulations is about whether you can build it safely and to standard (structure, fire, thermal, drainage). Most projects need both, and we deliver the full package end-to-end.
Do I need an architect or an architectural technologist?
For 80% of Wandsworth extensions, lofts and renovations, an architectural technologist (MCIAT) is the right call — same chartered status, same insurance, lower fee, and tighter focus on technical delivery. For award-led one-off design, an architect (RIBA / ARB) may be a better fit. We’re honest about which your brief needs.
Are your architectural technologists chartered and insured?
Every TradeMatch-listed architectural technologist serving Wandsworth holds MCIAT or ACIAT chartered status, carries minimum £250,000 Professional Indemnity Insurance, and is verified by our 5-step KYC pipeline. Credentials are visible on each profile.
