Architecture & approvals
What drawings are needed for planning and building approval?
The difference between concept, planning, building and consultant drawings—and how coordinated documentation helps an approval proceed.
A drawing set should be prepared for its purpose. Early concepts communicate an idea; approval and construction documents must progressively resolve dimensions, levels, materials, compliance inputs and consultant coordination.
Concept and feasibility
At the beginning, drawings test whether the brief can fit the site and respond to planning controls, access, orientation and constraints. This is the right time to identify likely requirements for survey, planning advice, flood, bushfire, geotechnical, civil or structural input.
Planning documentation
Planning submissions commonly require a site plan, floor plans, elevations, sections and schedules supported by the information required by the relevant council or planning authority. The precise package varies by project and jurisdiction; local controls and application checklists should be reviewed rather than assumed.
Building approval and construction information
Building approval documentation develops the technical resolution. It may coordinate structural, energy, stormwater, fire-safety, waterproofing and other discipline requirements. A planning approval does not by itself provide all information needed to build.
Why consultant coordination matters
Uncoordinated drawings create approval questions and construction variations. Levels should align between architecture, drainage and structure; openings should match beams and bracing; and permit conditions should be traceable to the final documents. A clear responsibility matrix helps define who supplies each item.
Common questions
Frequently asked questions
Are planning drawings enough for a builder to price?
They may support an early estimate, but reliable construction pricing usually needs a more developed and coordinated set of documents and specifications.
Can one consultant handle every report?
A lead consultant can coordinate the package, but specialist reports must still be prepared by appropriately qualified practitioners where required.
