Definition
A detail drawing is drawn at a large scale such as 1:5, 1:10 or 1:20 and shows how to build a part that plans and sections cannot show clearly, such as waterproofing turning up a parapet, stone cladding fixing, or a stair and handrail detail.
Why it matters on a project
Most leaks and cracks start at details nobody drew. A good detail sets materials, thicknesses and layer order so nothing is improvised on site.
Common mistake
Issuing villa drawings with plans and elevations only, leaving waterproofing, parapet and lintel details to the site.
Frequently asked questions
Which details matter most in villa drawings?
