Drawing a floor plan for building control
Building control want to see that the work will meet the Building Regulations. Clear, scaled drawings make that quicker. Your building control body has the final say on what they need — this guide covers what is usually asked for.
START DRAWING — FREEWhat is usually asked for
- Existing and proposed floor plans, usually at 1:50 or 1:100.
- A section through the work, showing floor, wall and roof build-ups.
- A site or block plan, usually at 1:200 or 1:500, showing the building and boundaries.
- Notes or a specification describing materials and how the work meets the regulations.
Drawing the plans
Draw at real size with lines and offset for wall thickness, add door and window blocks, label rooms with room labels, and dimension the key sizes.
Showing materials
Use hatching for brick, blockwork, insulation and concrete, sized at real scale, and add notes with leaders.
Printing
Lay each drawing out on the print-ready sheet at the scale they ask for, with a title block showing title, scale, date and revision.
Questions
Do I need an architect for building control drawings?
Not always. Many small jobs are drawn by the builder or owner. For complex work, or where structural calculations are needed, use a qualified professional. Ask your building control body if unsure.
