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.

Architectural Technologist vs Architect vs Architectural Designer
Pick the right professional for the brief. Most UK householder applications need a technologist, not an architect.

| Architectural Designer / Draughtsperson | Unregulated | £600 – £1,800 | Small householder applications, no planning gatekeeping |

Plain-English definitions.
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.
- Architectural TechnologistMCIAT
- A chartered building-design professional, qualified by the Chartered Institute of Architectural Technologists (CIAT). Specialises in technical design, building science and the production of planning + building-regulations drawings.
- Article 4 DirectionA4D
- A formal notice issued by a Local Planning Authority that removes specified Permitted Development rights — meaning works that would normally not need planning permission do require it within the designated area.
- Lawful Development CertificateLDC
- A formal certificate issued by the Local Planning Authority confirming that proposed (or existing) works fall within Permitted Development. Typically required by solicitors, mortgage lenders and buyers.
- Permitted DevelopmentPD
- Building works that may be carried out without explicit planning permission under the Town and Country Planning (General Permitted Development) (England) Order 2015. Subject to size, height and siting limits.
Hounslow planning rules baked into your planning drawings.
Hounslow planning splits sharply by geography: the Chiswick wards in the east are dense with conservation areas (Bedford Park, Chiswick Mall, Strand on the Green) where material authenticity, sash-window detailing and rear-extension massing decide outcomes, while the western wards (Cranford, Feltham, Hatton) sit inside the Heathrow noise contour where acoustic glazing specifications and ventilation strategy carry as much weight as elevational design. Brentford is in transition under the Great West Corridor and Brentford Project regeneration frameworks, which overlay site-specific tall-building and frontage controls on top of Local Plan 2015. A borough-wide HMO Article 4 Direction removes permitted-development rights for C3 → C4 conversions, and three town-centre A4Ds (Brentford, Hounslow, Chiswick High Road) withdraw office-to-residential PD. Practical effect: a Chiswick rear extension is a heritage-evidence job, a Feltham loft conversion is an acoustic-spec job, and a Brentford flat conversion almost certainly needs full planning rather than prior approval.

What homeowners often miss
Chiswick conservation areas dominate the east of the borough — Bedford Park CA crosses the boundary with Ealing and is jointly managed, requiring liaison with both councils on shared boundary streets. Brentford is in active regeneration (Brentford Project, Great West Corridor) with site-specific design codes layered over Local Plan policy. The southern third of the borough (Hounslow West, Cranford, Feltham, Hatton) sits inside the Heathrow 57+ dB Lden noise contour, triggering NPSE / Policy CC2 material-spec scrutiny on glazing acoustic performance (typically 35–42 dB Rw secondary glazing or acoustic laminated units required), trickle-vent specification, and mechanical ventilation as alternative to openable windows. Osterley Park and Syon Park are Grade I registered parks with English Heritage / Historic England as statutory consultees on adjacent works. TfL is a consultee on the A4 / M4 / A40 corridor and Piccadilly / District line surface sections.
The questions homeowners ask before they commit.
How long does a planning application take in Hounslow?
The London Borough of Hounslow statutory determination period is 8 weeks for householder applications and 13 weeks for major schemes. Add 2–3 weeks for validation in Hounslow 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 Hounslow?
A standard Hounslow householder planning drawings package is £950 – £2,400 fixed. Hounslow-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 Hounslow planning context.
Do I need planning permission for an extension in Hounslow?
Most rear extensions in Hounslow fall within Permitted Development under Class A — but Article 4 Directions and Conservation Area designations frequently remove that right. We check London Borough of Hounslow'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 Hounslow planning portal need from me?
London Borough of Hounslow'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 Hounslow planning portal.
Will Hounslow's Conservation Areas affect my application?
Yes — Hounslow 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 Hounslow's adopted character appraisal.
Can you handle the planning submission and officer queries for me?
Yes. For every Hounslow 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.
