An architectural technologist (MCIAT) designs, details and submits planning + building-regulations drawings for residential and commercial projects.

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.

Richmond upon Thames-specific planning rules built into the fee.
Richmond upon Thames combines Georgian riverside terraces, UNESCO-listed Kew, the Royal Park escarpment and dense conservation-area coverage — meaning almost every domestic project triggers planning, listed-building or Article 4 considerations before a drawing is even started. Our architectural technologists prepare borough-compliant drawing packages for householder, listed-building consent and full applications, with case-officer pre-app dialogue baked into the fee.

What homeowners often miss
Richmond upon Thames is one of London's most heavily protected boroughs — over 70 conservation areas cover most of the residential fabric, and Kew Gardens (Royal Botanic Gardens) is a UNESCO World Heritage Site with a defined buffer zone that constrains height, massing and roofscape across Kew Green, Kew Road and North Sheen. London Plan Strategic View 9 (the Protected Vista from King Henry's Mound in Richmond Park to St Paul's Cathedral) and the Richmond Park setting policy LP 14 force scrutiny of upper-storey extensions and roof alterations across a wide arc of the borough. Petersham, Ham and Strawberry Hill carry additional setting protections (Grade I-listed Ham House, Horace Walpole's Strawberry Hill House); the Thames Policy Area runs the entire river frontage; and the borough applies the borough-wide Class E → C3 Article 4 (March 2022) plus the HMO Article 4 (December 2022), so most office-to-residential and HMO conversions need full planning permission.
The questions homeowners ask before they commit.
Do I need planning permission for a loft conversion in Richmond upon Thames?
Most loft conversions in Richmond upon Thames 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 Richmond upon Thames?
A standard householder planning application in Richmond upon Thames runs £950 – £2,400 for the drawings package. Richmond upon Thames-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 Richmond upon Thames planning application take?
The London Borough of Richmond upon Thames 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 Richmond upon Thames 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 Richmond upon Thames 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.
