Home extensions on the Central Coast
More room without moving: extensions planned around your block and budget, and joined properly to the house you have.
More room, without leaving the street you like
An extension is often the smarter move when the house is too small but the location is right. It is also more complex than a new build, because the new work has to tie into an existing structure, services and finishes.
Hemmens Building has extended homes at Buff Point, Terrigal and Berowra. The work has included open-plan kitchens and living areas, master suites with ensuites, new decks and a self-contained granny flat.
Dylan prices the job properly up front. That includes approvals, reports and the electrical, plumbing or structural upgrades older homes often need.

Home extensions questions
Got a different question? Give Dylan a call.
Can we live in the house while you extend?
Often, yes, especially for ground-floor rear extensions. It depends on how much of the house is affected and whether the work area can be safely closed off.
Do extensions need council approval?
Most need either a DA or a complying development certificate (CDC). The right path depends on the zoning, setbacks and design of the extension.
What does an extension cost?
It depends on the size, structure, finishes, access and approvals. The extension cost guide on this site walks through what drives the price, and a feasibility report puts numbers on your own project.
