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

- Article 4 DirectionA4D

- 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

City of London planning rules baked into your planning drawings.
The City of London is the historic Square Mile and the UK's primary financial district. Planning is administered by the City of London Corporation, a sui generis local authority with its own Local Plan, design panel, and policy regime distinct from the surrounding London boroughs. Almost the entire City is covered by conservation areas, and strategic-view policies (St Paul's Heights, Monument Views, LVMF corridors) constrain massing across most plots. Tall buildings are channelled into the Eastern Cluster; elsewhere, heritage and view protections dominate the design conversation. Fee uplift reflects the technical complexity of heritage statements, view-corridor analysis, and Corporation-specific validation requirements.
Article 4 Directions
- City-wide Article 4 Direction removing office-to-residential permitted development rights (Class O — in force since 2013, retained and renewed)
- Article 4 Direction removing light-industrial / storage / office → residential permitted development rights
- Article 4 Direction restricting demolition permitted development rights in conservation areas

What homeowners often miss
The City of London is uniquely governed by the City of London Corporation, not a London borough council, with its own Local Plan (City Plan 2040 emerging) tailored to the Square Mile. Almost every site sits within a conservation area. The City operates strict strategic-view protections including the St Paul's Heights policy (a 3D height grid protecting views of St Paul's Cathedral) and the Monument Views policy, plus London View Management Framework viewing corridors (e.g. from Alexandra Palace, Parliament Hill, Greenwich Park). Tall buildings are concentrated in the designated Eastern Cluster (around Bishopsgate / Leadenhall / Fenchurch Street) — outside this cluster, height is heavily constrained. The City applies its own design review (City Design Advisory Panel) on significant schemes.
The questions homeowners ask before they commit.
How long does a planning application take in City of London?
The City of London Corporation statutory determination period is 8 weeks for householder applications and 13 weeks for major schemes. Add 2–3 weeks for validation in City of London 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 City of London?
A standard City of London householder planning drawings package is £950 – £2,400 fixed. City of London-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 City of London planning context.
Do I need planning permission for an extension in City of London?
Most rear extensions in City of London fall within Permitted Development under Class A — but Article 4 Directions and Conservation Area designations frequently remove that right. We check City of London Corporation'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 City of London planning portal need from me?
City of London Corporation'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 City of London planning portal.
Will City of London's Conservation Areas affect my application?
Yes — City of London 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 City of London Corporation's adopted character appraisal.
Can you handle the planning submission and officer queries for me?
Yes. For every City of London 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.
