Building Regulation Drawings by Project Type
ARCHITECTURAL SERVICES & DESIGN
Loft Conversion drawings
Loft extension projects require careful consideration of structural changes, fire safety, insulation, and access requirements. Our loft conversion drawings help ensure your conversion meets the necessary standards. A structural engineer may be required for complex loft conversions to provide structural calculations alongside the technical drawings, ensuring structural integrity and compliance. Your building inspector will use these drawings throughout construction and issue a completion certificate once all work complies with regulations.

Garage and Property Conversion Drawings

Single Storey Extension Drawings
A single storey extension is one of the most common home improvement projects requiring building regulations approval. We prepare technical drawings for kitchen extensions, rear extensions and side extensions, including floor plans, sections, construction details, insulation, drainage, ventilation and structural coordination where required. For more detail, see our single storey extension design services. Our drawings give your builder clear information before work starts and provide building control with the details needed to assess the project.

Double Storey Extension Drawings
Double storey extensions usually need more detailed technical drawings because they involve greater structural loads, fire safety considerations, insulation requirements and coordination with structural engineers. We prepare building regulation drawings and construction details for two-storey extensions, helping contractors price the work accurately and giving building control a clear package for review. For more detail, see our double storey extension design services.
GET FREE QUOTEPlanning Drawings vs Building Regulations Drawings
Planning permission drawings focus on visual impact. They show the overall design of your project.
Building regulations drawings are technical documents. They show how the work will be built safely and how the project will meet required standards. They can include construction notes, floor plans, sections, insulation details, drainage information and structural coordination where required.
You often need both. But they serve different purposes. You need building regulations drawings even after planning permission is granted.
Building Regulations Explained
What are Building Regulations?
Building regulations set minimum standards for health, safety, welfare, accessibility and energy efficiency
They apply to most domestic building work. This includes extensions, conversions, and new builds. Every homeowner doing construction work needs to follow these regulations and relevant approved documents.
What are Building Control Drawings?
Technical drawings are detailed building regulations drawings that show how your project will comply with current regulations.
A complete set of drawings includes floor plans, structural details, insulation details, and ventilation requirements. The drawings and construction drawings together provide all technical information needed for building control submission and approval. These drawings are essential — any builder needs them to start work legally.
Our Self-Survey Process
Our self-survey process uses questionnaires, photo requirements and measurement guides to help you provide the information needed for your drawings. For more complex projects, we can advise whether a measured survey or site visit is required.
Building Regulations Drawing FAQ
Planning an extension, loft conversion or property alteration? These are the key questions homeowners ask about building regulation drawings, costs, timescales and approval.For a full overview of our design services, visit our architectural services page
How Do You Ensure Accuracy Without Visiting My Property?
We use a digital self-survey process supported by measurement guides, photo requirements and video consultations. This helps us collect the information needed to prepare accurate technical drawings without always needing a site visit.
If anything needs checking during the drawing process, we can arrange a video call to review specific areas with you. For more complex projects, we can also advise if a measured survey or 3D point cloud scan would be more suitable.
Our process is designed to reduce missing information, avoid unnecessary delays and give building control a clear drawing package to review
What Are Building Control Drawings?
Building control drawings are technical drawings that show how your project will comply with building regulations. They can include floor plans, sections, structural details, insulation, ventilation, drainage, fire safety information and construction notes required for approval.
Are Building Regulation Drawings the Same as Structural Drawings?
No. Structural drawings focus mainly on load-bearing elements such as beams, foundations and structural calculations. Building regulation drawings cover a wider package, including structure, insulation, ventilation, fire safety, drainage and other compliance details needed for building control.
Who Does Building Regulation Drawings?
Building regulation drawings are usually prepared by architectural technologists, architects, building designers or other qualified construction professionals. At AC Design Solution, our drawings are prepared by MCIAT qualified professionals and supported through the building control submission process.
When Are Building Regulations Required for My Project?
Building regulations approval is required for many types of domestic building work, including extensions, loft conversions, garage conversions, structural alterations, new builds, major renovations and work affecting fire safety, drainage, insulation or structural stability.
Some minor works may be exempt or handled through competent person schemes, but it is always best to check before work starts. We can review your project and advise whether building regulation drawings are likely to be required.
Do I Need Building Regulation Drawings for an Extension?
Yes, most house extensions need building regulation drawings for approval. Whether you are planning a single storey extension, double storey extension, kitchen extension or rear extension, technical drawings help show how the work will meet structural, thermal, fire safety and ventilation requirements.
Can I Skip Building Regulations Drawings to Save Money?
Some homeowners consider skipping technical drawings to save money, but this can create problems later. Without a clear drawing package, builders may price the work differently, key construction details may be left to site judgement, and building control may raise more questions during the approval process.
Building regulation drawings give your builder and building control officer clear information before work starts. They can show structural details, foundation information, insulation, ventilation, drainage, fire safety measures, section details and other construction notes needed for the project.
A proper drawing package helps reduce uncertainty, supports building control approval and gives you a clearer record of how the work should be built
Building Notice vs Full Plans Application
You usually have two routes for building regulations approval: a building notice or a full plans application. A building notice can be quicker, but it gives less certainty before work starts. A full plans application allows the drawings and details to be reviewed in advance.
We can advise which route suits your project and handle the building control submission as part of the drawing package.
What's the Complete Timeline from Start to Approval?
Initial consultation and quote: same day
Drawing production: 5–10 working days, depending on complexity
Building control submission: 1–2 days after drawings are ready
Building control review: usually several weeks, depending on the provider
We will give you a clearer expected timescale once we understand your project, drawing requirements and chosen building control route.
