Building Regulations

Build With Confidence, Build to Code

Once your planning permission is approved—or if your project falls under permitted development—your next essential step is Building Regulations approval. At Arch One, we prepare the detailed technical drawings and specifications required to meet current UK building standards, helping you move forward with a safe, legal, and build-ready project.

What Are Building Regulations?

Building Regulations are a set of legally enforceable standards in the UK that ensure buildings are safe, structurally sound, energy-efficient, and accessible. They cover everything from insulation and ventilation to fire safety, drainage, electrics, and structural integrity.

While planning permission focuses on how a building looks and fits within its surroundings, building regulations ensure that the construction itself is done correctly and safely.

When Do You Need Building Regulations Approval?

You will typically need Building Regulations approval for:

  • Extensions (rear, side, loft, or two-storey)
  • New builds or conversions
  • Structural alterations (e.g. removing load-bearing walls)
  • Garage or loft conversions
  • Outbuildings intended for sleeping or living
  • Internal layout changes involving drainage or ventilation
  • Window and door replacements in certain cases

Some minor works may be exempt, but we’ll advise you on what’s needed based on your specific project.

Our Building Regulations Services

At Arch One, we prepare and submit comprehensive Building Regulations packages that ensure full compliance and provide everything your builder needs to construct safely and legally.

Detailed Technical Drawings

We produce precise construction drawings that meet current UK Building Regulations. These include structural details, insulation, foundations, drainage, ventilation, fire safety, and accessibility.

Building Control Submission

We submit your Building Regulations package to either the local authority’s building control team or a private Approved Inspector. We handle all communication and make any adjustments required for approval.

Structural Engineering Coordination

Where required, we collaborate with structural engineers to include calculations and specifications for beams, foundations, and load-bearing elements.

Ongoing Support

We’re on hand to assist during the construction phase, helping you or your builder interpret the drawings and answer any technical questions.

Our Process

Here’s how we help you secure Building Regulations approval:

Design Review

We assess your approved planning drawings (or permitted development design) and identify what’s needed for Building Regulations compliance.

Technical Drawings Preparation

Our team prepares a full set of detailed architectural drawings including plans, sections, elevations, construction details, and notes covering all relevant regulations.

Engineering Coordination

We liaise with structural engineers to include all necessary calculations and specifications.

Submission to Building Control

We submit your application to the appropriate Building Control body and respond to any technical queries or requested amendments.

Construction
Support

As your project progresses, we’re available to support with technical advice or design clarifications to ensure smooth execution on site.

Why Building Regulations Matter

  • Legal Compliance – You’re required by law to meet these standards for most construction work.
  • Build Quality – Ensures the work is safe, structurally sound, energy efficient, and durable.
  • Future-Proofing – Compliance is often essential when selling your home or obtaining insurance.
  • Clear Instructions for Builders – Our detailed drawings help prevent misunderstandings and costly mistakes during construction.
