Need Building Regulations drawings for an extension, loft conversion or renovation? These detailed construction drawings are used by Building Control and your builder to show how the work will be built to comply with UK Building Regulations. Your architectural designer personally visits the property during the measured survey to discuss your ideas and assess the proposed design in the context of the existing building before preparing the technical package. At Draw & Plan, we prepare Building Regulations drawings in London, with construction details and written specifications to help homeowners move from planning approval through to construction.
Our Building Regulations plans—also known as building regulation drawings, building regs drawings or Building Control drawings—are available across England and all London boroughs. Fixed fees start from £1,450 + VAT; where suitable existing drawings are provided, the reduced package price starts from £950 + VAT.
For borough-specific context, see our extension and loft conversion drawings in Sutton.

Technical design information
Building Regulations drawings are detailed technical documents that show how a project will comply with the regulations. Your architectural designer personally visits the property to carry out the Measured Building Survey, discuss your ideas and assess the proposed design against the existing building before preparing the technical package. The drawings cover construction details, materials, safety and performance standards, and are usually read alongside written specifications and any required structural calculations. You can commission them on their own, or as the final stage of a complete residential architectural design package.
Different purposes
Planning Drawings show what a project will look like. Building Regulations drawings explain how it will be constructed safely and to the required performance standards.
Technical drawing package
A complete, fixed-fee technical package that begins with a personal survey and design discussion at your property, then supports Building Control review and construction.
Unlike many online drawing services, our Building Regulations drawings are prepared to help both Building Control and your builder, with clear construction details, written specifications and separate structural calculations where required. Structural calculations are additional and are not included in package prices.
Fixed-fee service
Our Building Regulations package, including a personal site visit by your architectural designer for the measured survey and design discussion, starts from £1,450 + VAT. If suitable existing drawings are provided, the reduced package price starts from £950 + VAT. The fixed fee is confirmed before work begins; see Services & Prices for our wider service packages.
Structural calculations from £950 + VAT. They are additional to the Draw & Plan drawing/package fees and are not included in package prices.
When they're required
They are commonly required for new buildings, extensions, loft conversions, structural alterations, conversions and changes of use.
Residential projects
For house extensions, our House Extension Drawings & Plans establish the proposed design, while this technical package brings together floor plans, elevations, cross-sections, drainage information, construction details and written specifications for Building Control review.
Our Loft Conversion Drawings set out the proposed layout and the construction information relevant to structure, fire safety, stairs, insulation and ventilation. Structural calculations may also be required.
Structural design
Structural calculations demonstrate that elements such as beams, columns, foundations and floor structures are designed to carry the required loads safely. They are commonly needed where walls are removed, new openings are formed or the project introduces new structural supports.
We collaborate with a structural engineer who will visit the site to assess the existing structure. Structural calculations are additional and are not included in package prices. We coordinate the engineer's information with our Building Regulations drawings so the plans, construction details and structural design form a clear package for Building Control and your builder.
Structural calculations from £950 + VAT. They are additional to the Draw & Plan drawing/package fees.
Routes to approval
Applications can be handled by Local Authority Building Control or a private Building Control provider, a service homeowners may also search for as an Approved Inspector. The right route depends on the project; read our guide to Building Notice vs Full Plans.
Option 1
Submit complete drawings before work starts. They are reviewed and a formal decision is issued, giving greater certainty before construction.
Option 2
A faster route for simpler domestic projects. Compliance is assessed through site inspections, with no pre-approval of the plans and greater risk if work does not comply.

Helpful answers
Your architectural designer personally visits your property during the measured survey to discuss your ideas and assess the proposed work against the existing building. The resulting Building Regulations drawings show how the work is intended to meet the relevant technical requirements, supported by construction details and a written specification.
Usually, yes. Planning permission considers the principle and appearance of the development, while Building Regulations deal with how it is constructed. Your architectural designer can use the survey visit to discuss the approved design with you and coordinate the technical information, including structure, fire safety, insulation, ventilation and drainage.
Yes. The architectural designer personally visits your property during the measured survey, discusses your ideas and explores how the proposed technical work relates to the existing building before preparing the drawings.
You may still need them. Planning permission and Building Regulations are separate. Even when work falls within Permitted Development, the construction must still comply with Building Regulations.
Planning drawings are not normally detailed enough for construction. Building Regulations plans add construction sections, material build-ups, technical notes, drainage information and other details needed by your builder and Building Control.
Yes. Our package is prepared to support construction and includes plans, sections, construction details and a written specification. Where required, it should be read alongside separate structural calculations from the structural engineer we collaborate with. Structural calculations are additional and are not included in package prices. It should also be read with Building Control instructions.
A Full Plans application submits the complete drawing set for review before work starts and provides a formal decision. A Building Notice is a faster route for simpler domestic projects, with compliance assessed through site inspections rather than pre-approval of the plans.
The review period depends on the application route, the Building Control provider and whether amendments or further information are requested. A Full Plans application is reviewed before a formal decision is issued; a Building Notice does not provide advance approval of the plans.
Building Regulations drawings are typically issued within seven days of the measured-survey appointment and instruction. Timing can vary with the project’s complexity and the availability of structural or other specialist information.
Structural calculations from £950 + VAT. They are additional to the Draw & Plan drawing/package fees and are not included in package prices; we coordinate the structural information with our drawings.
Yes. Building Control submission support is available as part of our Building Regulations drawings service.
