Building Regulation Drawings & Compliance
Meet Building Control Requirements with Expert Support
When you need building regulation approval for an extension, loft conversion, garage or basement conversion, new build, or structural work, you’ll need accurate drawings that comply with building regs. These go beyond planning permission and are a required part of any building regulation application, ensuring your building project meets technical standards for structure, insulation, fire safety, ventilation, drainage, accessibility, sound, gas, and electrical systems in line with approved documents.
Our in-house team handles everything: detailed drawings, structural calculations, energy (SAP) reports, specifications, and full submission to building control—whether through a building notice or full plans via your local authority or an Approved Inspector. We help you comply with building regulations and reduce delays across all types of building work.
Our Process
STEP 1
Brief and review
We work from your planning drawings, site surveys or sketches and gather information to prepare initial drawings and specifications.
STEP 2
Technical design
Our team produces full construction drawings, structural calculations, SAP reports and detailed specifications, resulting in a complete set of approved drawings.
STEP 3
Submission & liaison
We collate all documents and submit a building regulations application, either through the full plans route or building notice, depending on your project. We handle inquiries or amendments at no extra charge.
STEP 4
Support for completion
We respond to builder or inspector queries during the build and continue to support until you receive your completion certificate.








What We Provide
Comprehensive Building Regulation Drawings
We provide detailed floor plans, elevations, and cross-sections with precise measurements and layouts for every stage of the build. These plans form the foundation for accurate construction, ensuring inspectors and builders have a clear reference throughout the project.
Structural Integrity & Safety Standards
Structural details for foundations, beams, lintels, and walls are prepared with a structural engineer’s input. Full fire safety specifications in line with Part B are also included, with escape routes, fire-resistant materials, and detection systems detailed to meet regulations.
Energy Efficiency & Environmental Compliance
Our drawings incorporate thermal performance data in accordance with Part L, including insulation levels and energy efficiency measures. We also ensure ventilation, drainage, and sound-proofing requirements meet Parts F, H, and E, creating healthy and comfortable living environments.
Electrical, Gas & Accessibility Requirements
Layouts for electrical systems (Part P) and gas safety features (Part J) are integrated into the plans, ensuring compliance with essential safety standards. Accessibility elements such as wider doorways, ramps, and inclusive bathroom designs are added in line with Part M.
Fully Approved Plans for Building Control
All drawings are delivered as approved, ready for submission to building control and suitable for use by architects and contractors. This approach speeds up approvals, avoids costly rework, and keeps your project running smoothly from start to finish.

Types of Building Regulations Applications
There are two main ways to apply for building regulations approval, depending on the type and complexity of your building work:
Full plans:
This is the most thorough option. You submit a complete set of drawings and documents before work begins. Plans are reviewed and approved by building control in advance, reducing the risk of delays or non-compliance during construction. This route is recommended for most structural projects and all commercial work.
Building notice:
A faster, more flexible option suitable for smaller domestic jobs. You notify building control without submitting full drawings up front. It’s useful when time is limited, but it puts more responsibility on the builder and may not be accepted for certain types of work.
Choosing the right building regulation application depends on your project’s size, scope, and risk. If you’re unsure which to use or need building regulation approval advice, we’ll guide you through the best route for your project.
