Founder Technologist

What does the founder technologist actually do on a project?

Every instruction is scoped by the founder before it reaches a drawing board. That means reading the site against three separate tests before any design work starts: whether the works fall inside permitted development under Schedule 2, Part 1 of the GPDO 2015; whether an Article 4 direction has withdrawn those rights at the address; and whether the property sits in a conservation area or is listed, either of which changes the application route and the evidence the council will expect.

Getting that call right is the difference between a £274 lawful development certificate and a £548 householder application decided over eight weeks — or, on a larger scheme, a £610 full application for a new dwellinghouse. It is also where most refusals are created. A scheme designed on the assumption of permitted development, then discovered mid-build to sit inside an Article 4 area, is a retrospective application and an enforcement risk.

What is MCIAT, and why does it matter for householder work?

MCIAT is the chartered grade of the Chartered Institute of Architectural Technologists, the body incorporated by Royal Charter in 2005 for the discipline of architectural technology. A chartered technologist's remit is the technical design of buildings: surveying an existing structure, preparing the drawn and written case for a planning application under the Town and Country Planning Act 1990, testing a scheme against the General Permitted Development Order 2015, and producing construction information that satisfies the Building Regulations 2010. “Architect” is a title protected by the Architects Act 1997 and reserved to those on the ARB register; “architectural technologist” is not, which is why the chartered grade matters — it is the check that the person doing your drawings has been assessed against a published standard.

For a rear extension, a loft conversion or a mansard, the work is almost entirely technical: dimensional accuracy, compliance with Approved Documents A, B, F, K and L, and a planning case that engages the council's own policy wording. Chartered technologist practice is built around exactly that.

Which London boroughs does the founder personally cover?

Camden, Hackney, Islington and Westminster — four authorities that between them hold some of the densest conservation-area coverage in the country and among the most restrictive Article 4 regimes. Westminster and Camden in particular treat roof alterations to terraces as a townscape matter rather than a household one, so a mansard there is argued on roofline continuity and materials, not on volume alone.

The 40m³ volume allowance for a terraced loft and 50m³ for a semi or detached house are the permitted-development ceilings, but in these four boroughs they are frequently academic: the Article 4 direction removes the right before the volume test is ever reached.

What the founder signs off before drawings are issued

Three checks, on every job. First, that the measured survey closes — that the recorded dimensions reconcile against each other rather than merely looking plausible. Second, that the planning drawings show existing and proposed at the same scale on the same sheet, which is what validation officers reject packages for more often than any design issue. Third, that the building regulations set answers Part B means of escape (a 4.5m upper-floor threshold, FD30 doors to a protected stair, 0.33m² clear escape openings), Part L U-values (0.18 W/m²K walls, 0.16 roofs, 1.4 windows, 2.2 rooflights) and Part K stair geometry (42° maximum pitch, 220mm minimum going, 2m headroom reducing to 1.9m at the centre of a loft stair).

How this looks in a named London borough

A worked Tower Hamlets example of founder technologist: with 58 conservation areas — the Spitalfields Conservation Area and the Whitechapel Market Conservation Area among the best known — London Borough of Tower Hamlets (Tower Hamlets Council) sees founder technologist constantly, and an Article 4 direction is in force there, so permitted development cannot be assumed. Where founder technologist pushes a Tower Hamlets scheme out of permitted development, the route becomes a £548 application decided in 8 weeks rather than a £249 prior approval in 6 weeks.
