Building Regulations Explained
What are Building Regulations?
Building regulations are legal requirements that ensure construction work meets minimum standards for health, safety, welfare, convenience, and energy efficiency. They apply to most building work, including extensions, conversions, and new builds. Every homeowner undertaking construction work needs to comply with these regulations.
What are Building Regulations Drawings?
Building regs drawings are detailed technical drawings that show how your project will comply with building regulations. A complete set of drawings includes structural details, insulation specifications, ventilation requirements, and other technical information needed for building control approval. These building control drawings are essential for any builder to commence work legally.
Planning Drawings vs Building Regulations Drawings
Planning permission drawings focus on the visual impact and overall design of your project. Building regulations drawings are technical documents that show how the work will be carried out safely and to required standards. You often need both, but they serve different purposes. A set of building regulations drawings is required even after planning permission is granted.

Building Regulation drawings FAQ
Planning a home extension? Our FAQ section addresses the key questions homeowners ask about structural engineering requirements, costs, timelines, and design processes to help you make informed decisions about your project.
Q. How Do You Ensure Accuracy Without Visiting My Property?
We use a proven digital process that often provides more accuracy than traditional site visits. Our detailed measurement guides, photo requirements, and video consultations capture everything needed. Plus, our systematic approach eliminates the human error that can occur during rushed site visits.
If any clarifications are needed during the drawing process, we’ll arrange a video call to walk through specific areas together. For complex projects where measurements don’t add up during design, we also offer 3D point cloud scanning services to ensure millimeter-perfect accuracy.
This comprehensive approach has resulted in a 98% first-time approval rate with building control.
Q. Why Trust Online Drawing?
Q. Can You Help With Planning Applications and Permitted Development Rights?
Yes, we can assist with various aspects of the planning process, including permitted development assessments and planning applications where required.
Q. Can I Skip Building Regulations Drawings to Save Money?
As a Chartered Architectural Technology practice, we often get questioned whether Building Regulation drawings are required. Some clients try to save in the wrong places. While not all projects legally require them, they’re crucial for ensuring compliance with Part A through Part R of the Building Regulations 2010 (as amended).
Building Regulation Drawings go far beyond basic architectural plans. They’re detailed technical documents that specify critical elements like:
- Structural calculations and beam specifications
- Foundation depths and construction details
- Thermal efficiency calculations (Part L compliance)
- Fire safety measures and escape routes
- Ventilation systems and condensation control
- Drainage layouts and connection details
- Sound insulation specifications for party walls
- Detailed section drawings at 1:20 scale
So why leave this to your builder on site? We understand your builder has built extensions repeatedly, but that doesn’t mean they’re equipped to design the whole scheme. For example, 100mm thick insulation doesn’t have the same U-value between manufacturers – you could end up with builder-made specifications that cause issues later.
Through our extensive experience, even when Building Regulation Drawings aren’t legally mandated, they prevent costly errors. A recent kitchen extension project saved our client £12,000 in potential remedial works because our detailed drawings identified a drainage issue before construction began.
Our professional experience shows comprehensive Building Regulation Drawings typically reduce construction costs by 5-15% through improved material specification and eliminating on-site guesswork.
If you’re planning a conservatory, don’t assume you’re exempt. Our 2025 guide to conservatory building regulations breaks down when approval is needed.
The real question isn’t whether you need Building Regulation Drawings, but rather what level of detail will best protect your investment and ensure full compliance.
