Planning Drawings and Building Regulations Drawings: What’s the Difference?
A straightforward explanation of Stage 1 planning drawings and Stage 2 technical working drawings for home extensions and conversions.
Robert Blake Designs prepares residential planning drawings for homeowners in Harlow, Essex and nearby Hertfordshire. Our service starts with a discussion of your proposal and a measured survey of the relevant property areas.
Stage 1: planning drawings
Planning drawings show the existing property and the proposed changes so the design and planning implications can be assessed. Depending on the project, this can involve plans, elevations, sections and submission of a planning application.
Stage 2: Building Regulations drawings
Building Regulations drawings typically contain further technical details, construction notes and specifications to support building control consideration. They are a different service from the drawings used to seek planning permission.
Do I need both stages?
Not every project requires a planning application, and Building Regulations requirements depend on the work proposed. Where both drawing stages are appropriate, Robert Blake Designs can explain the scope and provide separate or combined quotations.
Can I save by commissioning both stages?
Clients commissioning both Stage 1 and Stage 2 may benefit from a discounted combined drawing fee, subject to project scope and a written quotation. No fixed percentage is promised.
What is not included?
Robert Blake Designs does not provide structural engineering, structural calculations or structural design. These must be commissioned separately from a suitably qualified structural engineer where required.
