Testimonials
“From the initial quote, communications, build to completion – it was perfect! From the initial quote, the team were on time, respectful and even set out the build with pegs for a visual! The build started and was well underway seemingly in an instant. The quality was exceptional with a true value for money. Peter and the team put in the effort and focus on the detail. The team went above and beyond with the authorities for approvals and complexities with service connections! We could not be happier with the outcome and credit to the team. With our first baby on the way, the wife and I couldn’t be happier with our stress-free build. We will be recommending PJ Cook to our friends and if the future allows, going again with the team!”
“Peter was extremely professional from the start. Great communication all the way and has certainly been the best thing we ever did to generate a great investment income! I named our granny flat “Happy Cottage Woy Woy” as it is holiday accommodation and it makes people feel happy. I would highly recommend PJ Cook builders.”
“We have recently completed a lovely build with P J Cook and we couldn’t be happier – Peter and his whole team are a pleasure to work with. They consistently had an eye to the detail, levering off their successful experience, to improve the delivery for our construction – whether it was site management, finish details, materials pallets, or subcontractor management.

What could be better!”

Granny Flat Project: Ashtonfield, Maitland
This Granny Flat project, located in Ashtonfield within the Maitland City Council region, involved the construction of a stylish and functional 2-bedroom granny flat for a pair of local Maitland investors. The floor plan is a modified version of the Empire Bay 2-Bedroom Granny Flat design; the build was tailored to maximise the property’s potential for dual rental income. Focusing on quality and practicality, the project met the client’s brief to create a well-equipped space that would appeal to tenants and provide a strong return on investment. The Gillieston Heights granny flat is a shining example of PJ Cook Building’s commitment to craftsmanship, problem-solving, and delivering results that exceed expectations.
