Building Regulations Drawings · SW14 Mortlake
Richmond controls the Mortlake and East Sheen conservation areas; the former Stag Brewery is a major local redevelopment.
If your property sits elsewhere in the borough, the borough-wide page for building regulations drawings in Richmond upon Thames covers the same service across every ward.
Building regulations drawings for a Mortlake project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Richmond Council Building Control or an approved inspector. On SW14's edwardian and inter-war terraces and semis around, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around Mortlake, East Sheen, Sheen, North Sheen fringe.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Across Mortlake, East Sheen, Sheen, North Sheen fringe in SW14, the dominant property is edwardian and inter-war terraces and semis around mortlake and east sheen, with larger houses toward richmond park. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Richmond Council judges each on design quality and neighbour impact. We survey the specific Mortlake property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SW14 streetscape.

The former Stag Brewery site at Mortlake is being redeveloped into homes, a school and riverside public space, one of the borough's largest schemes, supporting values across SW14. For a house project the binding controls remain Permitted Development limits and the local conservation area, which we check for your address.
Usually yes on the semis and terraces — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate, provided you're not in the Mortlake or East Sheen conservation areas. We check the constraints for your road and draw it for Building Control.
With SW14 houses around £900,000-£1.4m and the appeal of Richmond Park on the doorstep, a side-return or loft adds family space worth well above the build and drawing cost.
With Mortlake property at around £450,000 for a flat and £900,000-£1.4m for a house, the professional drawing fee is a small fraction of the value the work adds to SW14's edwardian and inter-war terraces and semis around. Richmond Council charges its own statutory application fee on top (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every SW14 address.
For a SW14 project across Mortlake, East Sheen, Sheen, North Sheen fringe, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Richmond Council (8 weeks for a householder application).

Almost always. Any structural work behind building regulations drawings in Mortlake — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Richmond Council Building Control or an approved inspector. On SW14's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on SW14 homes.
Planning history and precedent stop at the borough line, so the comparable approvals nearby may sit elsewhere. See all services in SW13, TW1, TW2, TW9, TW10, TW11 and TW12.
