Building regulations drawings in Southwark
Southwark building regulations drawings are the construction set a building control surveyor tests against the regulations: floor, wall and roof sections, structure, drainage, the escape route and fire safety for your extension, loft or conversion. DrawingsDirect's starting fixed fee for a full plans drawing package is £745.

From submission to start on site
Once the full plans application is in, the authority must notify its outcome within five weeks of receipt, or a longer period agreed in writing (Building Regulations 2010, regulation 14A(6)). Work cannot begin until at least two days have elapsed since the end of the day the notice of intention to start was given (regulation 16(1)(b)).
Read both on legislation.gov.uk. Our building control in London guide covers the inspections that follow.
What the package contains
Sections through the floors, walls and roof, structure, drainage runs, the escape route and a specification naming the materials. Planning drawings against building regulations drawings shows how the sets differ.
If you have not yet been through planning, see planning permission in Southwark. For layouts before construction detail, our Southwark floor plans page covers that stage.
Southwark made 558 householder decisions over the four quarters 2025 Q3 to 2026 Q2, counting prior approvals, and 95% were granted.
Southwark's planning figures
Southwark made 558 householder decisions over the four quarters 2025 Q3 to 2026 Q2, counting prior approvals, and 95% were granted. Excluding prior approvals, 97% were decided within 8 weeks (our analysis of MHCLG planning application statistics, table PS2).
Of 72 householder appeals decided between 2021 and 2026, 31% were allowed (our analysis of the Planning Inspectorate Casework Database, release 2609). It is history, not a forecast.
The national register holds 56 conservation-area entries for Southwark (our analysis of the MHCLG Planning Data Platform conservation-area dataset, snapshot retrieved 14 Aug 2026). Check the council's conservation area map: a designation can change the planning route, while the Building Regulations still apply.
Our fee for the package
A building regulations full plans drawing package starts from £745. Building Control charges its own fee, and the pricing page lists the rest of ours.
