Whatever you want to call it, we can build it.  Granny flat, art stuido, home office, man cave, music room - we do them all!

Hardwood decks are a speciality of ours, maximising living space, and making the most of your outdoors.

We work with hardwoods suited to high fire-risk locations, or budget-friendly timbers, attractive stainless wire or glass balustrades and deck roofs with lighting and fans for the ultimate in outdoor entertaining comfort.

Be it ground level, first or second storey, no job is too big or small.

Keena Building Contractors is a small family business run by Jon and Sibella.  Jon has over 15 years experience in the building industry and extensive project management skills.

Our small size gives us advantages over larger builders - we can generally get projects underway much sooner than competitors, have shorter project timelines, and less overheads, which means a more affordable and faster service for you.

We have extensive experience in all aspects of building ranging from new homes and granny flats, through to decks, renovations and extensions.  No job is too big or too small for our team and a quality finish is assured.  Jon quotes the job and undertakes the carpentry work while managing our highly skilled team of tradesmen.
