"We engaged Michael Cotter from Cotter Builders to complete renovations of our 25 year old house. (It needed a major Reno). Prior to the commencement of construction works the design work was documented by Cotter Builders. It was nothing short of amazing, there was nothing that couldn’t be done when we started on the Design of our Renovations. Every detail and issue we came across was resolved through multiple conversations and documented draft issues. Every detail of the renovation from colour selection, product selection and material were carefully selected by Cotter Builders.We knew exactly what we were getting and what was quoted before the renovations commenced.


Micheal from Cotter Builders has the best sub contractors-Tilers, Electricians, Plasterers, and Plumbers. All sub-contractors were on time, polite, and produced high quality workmanship, I would highly recommend them to anyone building or renovating. Just look at the before and after photos.

Cotter Builders were a pleasure to work with."
