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.

Hammersmith & Fulham planning rules baked into your architectural design.
Hammersmith & Fulham combines Victorian terraces (Fulham, Brackenbury Village, Munster Village), Edwardian mansion blocks around Hammersmith Broadway, riverside heritage at Bishops Park, Crabtree and Fulham Reach, and the White City and Earls Court Opportunity Areas where consented towers reach up to 42 storeys. 44 designated Conservation Areas cover a substantial part of the borough, and a borough-wide Article 4 Direction (in force since 26 April 2018) removes Permitted Development rights for basement development — every basement scheme requires full planning permission, a Construction Method Statement, and compliance with the Planning Guidance SPD's 50% garden / 50% host-building depth caps. Conservation-Area-specific Article 4 Directions cover Bishops Park, Crabtree, Walham Green, Ravenscourt & Starch Green, Old Oak & Wormholt and others, removing PD on minor external alterations; pre-application advice is essential before any frontage change.
Article 4 Directions
- Borough-wide Article 4 Direction — Basement Development. Made 25 April 2017, confirmed 16 April 2018, in force 26 April 2018. Removes PD rights for basement development across the entire borough (excluding the OPDC area).
- Old Oak & Wormholt Conservation Area — Article 4 Direction restricting minor alterations (windows, doors, roofs, boundary walls); originally made June 1984
- Bishops Park Conservation Area — Article 4 Direction on minor alterations to retain Victorian character around Fulham Palace and the riverside

What homeowners often miss
Hammersmith & Fulham has 44 designated Conservation Areas (plus 2 in the OPDC area) covering a substantial proportion of the borough — Victorian terraces in Brackenbury and Bradmore, mansion blocks around Hammersmith Broadway, riverside heritage at Bishops Park, Crabtree and Fulham Reach, and the Walham Green / Parsons Green core. A borough-wide Article 4 Direction (in force since 26 April 2018) removes Permitted Development rights for basement development; every basement scheme requires full planning permission and a Construction Method Statement under the Planning Guidance SPD, with basements capped at 50% of garden area and 50% of host-building depth. Two further regulatory shifts are imminent: a Class E → C3 Article 4 Direction (consultation closed January 2025) and a borough-wide HMO C3 → C4 Article 4 (Cabinet-approved 9 February 2026, in force 12 months after publication). Major regeneration zones at White City and the Earls Court Opportunity Area (allocated in the Local Plan 2018, with consented towers up to 42 storeys) define the borough's tall-building envelope.
The questions homeowners ask before they commit.
What's included in a Hammersmith & Fulham 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 Hammersmith & Fulham. 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 Hammersmith & Fulham?
Typical fee for end-to-end design on a Hammersmith & Fulham 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 Hammersmith & Fulham project?
For 80% of Hammersmith & Fulham 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 Hammersmith & Fulham 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 Hammersmith & Fulham 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 Hammersmith & Fulham we recommend at least one streetscape visualisation to support the heritage statement.
Can you also handle structural and party-wall work in Hammersmith & Fulham?
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 Hammersmith & Fulham terrace and semi-detached extensions under the Party Wall etc. Act 1996. We can introduce a regulated party-wall surveyor when needed.
