Home Extensions & Additions Draftsman Central Coast

Extending your home can be a great move, but it has to be done right. That means plans that are accurate, practical, and meet the rules.

With True Blue Drafting, you get:

What’s included in your home extension plans on the Central Coast?
Our home extension drafting service includes a full set of site-specific plans. This covers floorplans, roof layouts, elevations, section views, and construction details. We show all internal changes like walls, plumbing and electrical updates, plus any structural elements that need engineering. We check site setbacks, bushfire overlays, and drainage issues, then prepare documents for your DA, CDC or Construction Certificate. We also help with BASIX if it’s required. Everything is drawn to meet Central Coast Council standards so your builder can quote and build with confidence.

Do I need council approval for a home extension on the Central Coast?
In most cases, yes. If your extension changes the footprint, increases height, adds new plumbing or alters a wall, it likely needs approval. Depending on your property zoning and the size of the extension, you might qualify for a Complying Development Certificate (CDC). If not, you’ll need a Development Application (DA). We assess your site and tell you exactly what approvals you need. We can then handle the submission and track it through to sign-off.

How long does it take to get home extension plans ready?
Once we have your brief and any site details like a survey, most extension plans are drafted within 1 to 2 weeks. The approval timeframe depends on whether it’s a CDC or DA, and how quickly council processes the paperwork. DA approvals often take longer due to neighbour notification and assessment periods. We’ll give you an honest estimate and keep you updated every step of the way.

Can you work with my builder or private certifier on the extension plans?
Absolutely. We regularly coordinate with builders and certifiers across the Central Coast. We make sure your plans meet the certifier’s needs so there are no surprises during construction. If any tweaks are needed along the way, we’ll revise the plans and resend without delay. Our goal is to help you build sooner and smoother.

Do you draft home extension plans across the whole Central Coast?
Yes. We service every suburb from Gosford and Terrigal to Woy Woy, Bateau Bay, Toukley, and beyond. As locals, we understand the different rules for each area including bushfire zones, flood risk, and slope issues. No matter where you are on the Coast, we can help you plan and approve your home extension the right way.
