Building Regulations drawings

Detailed technical drawings that prove your project complies.

Building Regulations Drawings are detailed technical documents that illustrate how a building project will comply with the regulations. They are concerned with construction details, materials, and compliance with safety and performance standards — typically accompanied by written specifications and structural calculations.

What they contain

A typical Building Regs drawing pack

Detailed floor plans, elevations and sections
Construction methods and materials

When they're required

Most construction work

Constructing a new building
Building a home extension
Carrying out a loft conversion
Altering the structure of a property (e.g. removing load-bearing walls)
Converting a garage or basement
Changing the use of a building (e.g. house to flats)
