Complete Building Services

Coffs Coast Building provides expert home extensions and additions to all customers in Coffs Harbour, Nambucca, Bellingen, and surrounding areas. Our fully licenced and insured crew of expert tradespeople can professionally handle every step of your next building project, from start to finish.

We can provide design and layout advice and can even submit the plans for Council approval on your behalf. Having agreed upon a design plan, one of our team members can provide you with a no-obligation quote and proceed the project from there. We oversee every step of any building project we take on, from design and initial planning, to preparation, demolition, build, and clean-up. Property owners can rest easy knowing they won’t have to chase up different companies and trades, waiting around for call-backs. We ensure peace of mind to all our customers, assuring them that we provide a professional and comprehensive all-in-one building service.

Not Just Granny Flats

From adding a first floor to your current home, to extending your ground floor space, to adding detached and semi-detached ancillary living spaces – Coffs Coast Building can handle all forms of extensions and additions for the home, helping you maximise your living spaces and achieve your dream build projects. 

Our range of granny flats or detached/semi-detached living spaces can be built using traditional double-brick construction methods, for long-lasting quality builds. All our home additions and extensions are designed for year-round comfort, with a 6-star energy rating, custom designed to match or complement your main home, and usually completed within 10-14 weeks.


There is no limit when it comes to designing and building an additional living unit for your home. Whether you are looking to construct a secluded backyard retreat, a home office, work shed, or guest house, the Coffs Coast Building team can make your next dream project a reality.
