What Are Building Regulations Drawings?

Building Regulations drawings, also known as building regs drawings or building control drawings, are detailed technical plans and construction specifications prepared to demonstrate how proposed building work is intended to comply with the applicable Building Regulations in England.

Unlike planning drawings, which primarily illustrate a development's layout, design and appearance, Building Regulations drawings provide the technical information needed for Building Control assessment and to guide the construction process.

They typically address structural safety, foundations, wall and roof construction, thermal insulation, fire safety, ventilation, drainage and other requirements relevant to the proposed works.

SMARTePLANS® prepares professional Building Regulations drawings for residential extensions, loft conversions, garage conversions and structural alterations, with fixed-fee services starting from £595.

What's Included in Our Building Regulations Drawings?

Every project is different. Our technical drawing packages are prepared around the particular building work proposed, with the following information included where applicable.

1. Existing and Proposed Floor Plans

Dimensioned architectural drawings showing the existing property and proposed alterations, including room layouts, wall positions, openings, staircases and relevant construction dimensions.

2. Building Sections and Construction Details

Technical sections and enlarged construction details illustrating how the proposed building elements are intended to be constructed.

These may include:

• Foundation arrangements and ground-floor construction
• External cavity walls and internal partitions
• Flat and pitched roof construction
• Floor, wall and roof insulation
• Damp-proof courses and membranes
• Window and door junctions
• Structural openings and connections

3. Thermal Insulation and Energy Efficiency

Technical specifications addressing relevant energy-efficiency requirements under Approved Document L.

These may identify insulation materials, construction build-ups, thermal performance requirements and U-values.

4. Fire Safety and Means of Escape

Project-specific information addressing relevant provisions of Approved Document B, including fire-resisting construction, escape routes, smoke detection and protected stairways where required.

5. Ventilation and Moisture Control

Information addressing relevant ventilation and moisture-control requirements, including mechanical extract ventilation, background ventilation and condensation considerations.

6. Drainage Layouts

Where applicable, drawings showing proposed foul and surface-water drainage arrangements, inspection chambers, pipe routes and connections.

7. Structural Engineering Coordination

Structural openings, beams, lintels and other load-bearing elements can be identified and coordinated with structural engineering designs.

Structural calculations and specialist engineering designs are available as additional services where required.

8. Construction Specifications

Relevant technical notes and material specifications to support Building Control assessment and assist contractors in understanding the proposed construction.

Our objective is to provide clear, coordinated technical drawings that support Building Control assessment and help reduce uncertainty during construction.

Garage Conversions

Technical specifications for converting existing garages into habitable accommodation, including floor construction, insulation, ventilation, fire protection and alterations to external openings.

Internal Structural Alterations

Drawings for removing load-bearing walls, forming structural openings, installing new staircases and undertaking internal reconfiguration.

Outbuildings and Annexes

Building Regulations drawing packages for relevant outbuilding and annex projects, where the proposed works are subject to Building Regulations requirements.

Flat Conversions and HMOs

Technical drawing services for residential subdivisions and HMO conversions, including coordination of relevant fire safety, acoustic separation, ventilation and other specialist requirements.

Larger Residential Projects

We also assist with more complex residential alterations and conversions requiring coordinated architectural, structural and specialist technical information.

Building Control Compliance — Which Regulations Apply?

Building Regulations drawings are prepared with reference to the relevant requirements of the Building Regulations and associated Approved Documents in England.

Depending on the project, these may include:

• Part A — Structure: Structural stability and load-bearing construction.
• Part B — Fire Safety: Means of escape and fire protection.
• Part C — Site Preparation and Moisture: Resistance to moisture and relevant ground conditions.
• Part E — Resistance to Sound: Acoustic performance and sound insulation.
• Part F — Ventilation: Ventilation of habitable rooms and other spaces.
• Part G — Sanitation and Water Efficiency: Sanitary facilities, hot water safety and water efficiency.
• Part H — Drainage and Waste Disposal: Foul and surface-water drainage.
• Part K — Protection from Falling: Stairs, guarding and relevant safety provisions.
• Part L — Conservation of Fuel and Power: Thermal insulation and energy performance.
• Part M — Access to and Use of Buildings: Relevant accessibility provisions.
• Part P — Electrical Safety: Electrical installation safety.

Not every requirement applies to every project. Our drawing specifications are tailored to the relevant work and coordinated with specialist information where necessary.

Building Control approval is determined by the relevant Building Control body and cannot be guaranteed by the preparation of drawings alone.
