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.

GLOSSARY

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.

PLANNING CONTEXT — EALING

Ealing planning rules baked into your architectural design.

Ealing covers a vast, architecturally layered slice of west London — from Bedford Park's red-brick Aesthetic Movement villas to Southall's Edwardian terraces, Acton's mixed-tenure stock and Northolt's post-war estates. With around 367,100 residents (Census 2021), thirty conservation areas and a borough-wide HMO Article 4 direction landing 14 November 2025, every architectural-technology brief here turns quickly into a planning-strategy brief. Our Ealing-vetted architectural technologists handle Idox PAM submissions, Bedford Park and Brentham CA design-and-access statements, party-wall coordination on tight Victorian plots, SAP/SBEM compliance for rear extensions, and Listed Building Consent where it bites. Whether you are converting a Hanger Hill semi, extending in Pitshanger or refurbishing a Hanwell terrace, the fee band reflects Ealing's heritage-and-Heritage-Application complexity.

What homeowners often miss

Ealing is the architectural-technologist's London puzzle box: Bedford Park (W4) is officially the world's first garden suburb, designated by Norman Shaw from 1875 onward, and its Conservation Area controls scrutinise every sash, render colour, and roof tile. Brentham Garden Estate (1901, Parker & Unwin) and the two Hanger Hill estates layer further Article 4 protection over inter-war suburbia. Borough-wide HMO Article 4 (non-immediate) takes effect 14 November 2025, with Perivale already locked down since 30 October 2024 — every C3-to-C4 conversion now needs full planning. Heathrow noise contours, the Wharncliffe Viaduct setting at Hanwell, and Crossrail-driven density around Ealing Broadway all add policy weight that pure design-build cannot ignore.

FAQ

The questions homeowners ask before they commit.

What's included in a Ealing architectural design service?

Concept design (sketches + 3D), planning permission drawings, building regulations package, tender drawings + schedule of works, and optional contract administration. Fixed-fee on conventional briefs in Ealing. The MCIAT lead is the same person from concept to completion — no handoff between practices.

How does architectural technology pricing work for a full design in Ealing?

Typical fee for end-to-end design on a Ealing extension or loft is 6 – 10% of build cost, with the upper end on Conservation Area schemes that need extensive heritage justification. Outside Conservation Areas, fixed-fee bands are common: £4,000 – £8,000 covers concept through to building regs on most householder briefs.

Architect or architectural technologist for my Ealing project?

For 80% of Ealing extensions, lofts and renovations, an architectural technologist (MCIAT) is the right call — same chartered status, same insurance, lower fee, tighter focus on technical delivery and fewer hand-offs. For award-led one-off design or listed-building consents, an architect (RIBA / ARB) may be a better fit. We are honest about which your brief needs.

Will you handle the Ealing planning + building regs together?

Yes — single MCIAT lead, single fee, single point of accountability. Planning and building regs run in parallel where the brief allows: planning sketches go in at week 4–6, building regs technical work continues in the background, both packages are submitted and discharged in sequence so the build start date is not delayed.

Do you provide 3D visuals for Ealing design?

Standard fee includes 2 × 3D massing sketches (existing + proposed) for planning. Photoreal interior / exterior visualisations are an upgrade — typically £400 – £900 per camera on top of the design fee. For Conservation Area schemes in Ealing we recommend at least one streetscape visualisation to support the heritage statement.

Can you also handle structural and party-wall work in Ealing?

Structural calculations are bundled with our design service via a CEng MIStructE associate. Party-wall awards are a separate service (typically £600 – £1,500 per neighbour) and are required on most Ealing terrace and semi-detached extensions under the Party Wall etc. Act 1996. We can introduce a regulated party-wall surveyor when needed.
