Building plans are a language. You do not need to draft them to understand what you are approving — a little literacy prevents expensive misunderstandings.
Core drawing types
- Floor plans — horizontal layout
- Elevations — exterior appearance
- Sections — vertical cut-throughs
- Details — how pieces meet
- Schedules — doors, windows, finishes
Scale and notes
Drawings are scaled; dimensions rule over “it looked bigger on my phone.” Notes and legends carry legal and technical meaning.
What to review as an owner
Room sizes, circulation, storage, window placement, and anything that affects daily life. Technical systems still need professional coordination.
Revisions
Clouds and revision numbers track changes. Always confirm you are looking at the latest set before deciding.
