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.

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

| Architect (ARB / RIBA) | ARB + RIBA | 8 – 12% of build cost | Award-led design, listed buildings, major commercial |
| 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.

- Article 4 DirectionA4D

Bromley-specific planning rules built into the fee.
Bromley is outer south-east London at its leafiest — a borough where Green Belt countryside, conservation-area suburbs and post-war estates sit side by side. For homeowners and developers, that mix means the planning route here is rarely standard: a rear extension in Park Langley, a replacement dwelling in Keston or a loft conversion in Beckenham each follow very different rules. Our chartered architectural technologists work across all 47 Bromley Conservation Areas and the borough's extensive Green Belt, preparing measured surveys, planning drawings, design and access statements and Building Regulations packages tailored to LB Bromley's validation list and adopted Local Plan policies.
Article 4 Directions
- Park Langley Article 4 Direction — removal of permitted-development rights for alterations to dwellinghouses
- Chislehurst Conservation Area Article 4 Direction restricting permitted development on dwellinghouses
- Bickley Park Article 4 Direction over dwellinghouses

What homeowners often miss
Bromley is the largest London borough by area, and roughly 50% of its land is designated Metropolitan Green Belt — a defining planning constraint that shapes almost every project outside the urban centres. Replacement dwellings, extensions and outbuildings in Green Belt locations such as Cudham, Downe, Keston and Farnborough are tightly controlled by openness and volumetric tests, and householder PD rights are often curtailed. The borough also holds 47 Conservation Areas, more than most London authorities, with strong character protection in Chislehurst, Beckenham (Cator Estate, Copers Cope), Park Langley, Bickley and Petts Wood. Article 4 Directions remove permitted development rights in several of these, so even small front-elevation alterations need full householder consent.
The questions homeowners ask before they commit.
Do I need planning permission for a loft conversion in Bromley?
Most loft conversions in Bromley 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 Bromley?
A standard householder planning application in Bromley runs £950 – £2,400 for the drawings package. Bromley-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 Bromley planning application take?
The London Borough of Bromley 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 Bromley 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 Bromley 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.
