Renovation and extension drawings in Sydney: what you need

A renovation starts with what is already there. Here is the set of drawings that takes it from idea to build.

Start with the existing home

Renovation and extension drawings start from survey and existing plans, because the new work has to join the old. If you have no plans, they can be drawn from measurement. Sketches and existing plans are both acceptable starting points.

The drawings and documents

• Concept plans: to settle the layout and see the result.
• Council drawings: for the development application or complying development certificate.
• Working drawings and specifications: the construction set a builder prices and builds from.
• Schedules: fixtures, finishes and detail packages.

Council checks and BASIX

The design is checked against council controls and buildability before it is lodged. If the work is an alteration or addition of $50,000 or more, a BASIX certificate is needed. See BASIX explained and DA vs CDC drawings.

Drafting only

You do not have to use a full design service. A designer can work from your sketches or existing plans and prepare the documentation, including checks against council controls and buildability. That suits owners who already know what they want.

Getting started

Renovation and extension drawings from a Sydney building designer include working drawings, specifications and schedules, with consultant documents coordinated.
