Building Regulations Drawings in New Cross SE14
Fixed-fee, MCIAT-chartered building regulations drawings for New Cross (SE14) homeowners — London Borough of Lewisham validation and local constraints handled from the start.
New Cross (SE14) climbs from the busy New Cross Road up into the Victorian streets of Telegraph Hill and the terraces behind Hatcham, and our work here is mostly rear extensions, side returns and loft conversions on that period housing.
Both the Telegraph Hill and Hatcham conservation areas carry Article 4 directions, so several normally-permitted changes need consent, and we check the boundary and the direction before advising on a permitted-development or full householder route.


Planning in New Cross (SE14): what to know before you apply
Inside the Telegraph Hill or Hatcham conservation areas the Article 4 directions mean front-facing and roof changes usually need planning permission. We confirm the designation for your street and prepare drawings to Lewisham standards.
Typical New Cross housing stock
Telegraph Hill is a largely residential grid of steep Victorian streets and villas above New Cross, while Hatcham combines commercial frontages on New Cross Road with Victorian terraces behind, plus later flats and student housing.

Building Regulations Drawings for New Cross (SE14) homes: the package and the process
A Full Plans submission is a technical argument, not a picture. The sheets carry construction build-ups for floors, walls and roof, insulation values and junction details, drainage runs and invert levels, fire escape routes and protected stairs, ventilation provision and the structural elements that carry it all. Building Control checks each against the Approved Documents before work starts.
We coordinate the structural design with the architectural sheets in-house, so the beam sizes on the calculations are the beam sizes on the sections, and the openings your builder prices are the openings that were approved. Where a detail is unusual, we draw it rather than leave it to be resolved on site.
Construction details follow the existing fabric. Solid brick walls, suspended timber floors and uninsulated roofs each need a different build-up to reach the required performance, and a terrace has party wall junctions to detail that a detached house simply does not.
What do building regulations drawings cover?
A building control package translates the approved design into a buildable, compliant specification.
- Construction sections and detailed junctions
- Structural drawings and calculations (steel beams, foundations, loadings)
- Part L thermal performance and insulation specification
- Fire safety — escape routes, protected structure, alarms
- Drainage and ventilation layouts
Full Plans or Building Notice — which should I choose?
A Full Plans application has your drawings checked and approved by Building Control before work starts, giving certainty and a document lenders and buyers like to see. A Building Notice lets simpler work start sooner but is inspected as it proceeds, with less up-front certainty. For most London extensions and loft conversions we recommend Full Plans, and prepare the package accordingly. Building regulations are a separate consent from planning permission, and the two are often confused — the explainer on permitted development rights sets out which projects escape a planning application but still need building-regs approval, and Architectural Drawings covers the same building-regs package where you want a chartered practice to carry it through to sign-off.
Why coordinate structural calculations in-house?
When the same team draws the building and calculates its structure, the steel schedule matches the drawings and the builder never waits on a missing detail. It removes the classic gap between an architect's drawings and a separately-appointed engineer's calculations.
| Factor | Full Plans | Building Notice |
|---|---|---|
| Drawings checked before work starts | Yes | No |
| Up-front certainty | High — approval in writing | Lower — inspected as built |
| Best for | Extensions, lofts, structural work | Minor, simple works |
| Evidence for lenders and buyers | Full approval record | Completion certificate only |
| Risk of costly on-site rework | Low | Higher if issues are found late |
