What our landscape design clients say


Mandy & Martin Croft

“It was an easy choice to ask Cullen to help redesign our backyard and incorporate a new concrete pool at our home in Subiaco. I bought a few magazines and looked for designs we liked the most, and they were nearly all his work. When I contacted him to discuss the project I immediately felt at ease. He was really easy to relate to, and very quickly came up with a plan that was exactly what we wanted. He did a great job of keeping the project running on time and to the budget he outlined.

His crew were a great bunch of blokes. The enthusiasm they had for their work was wonderful to see, and the quality of their work was outstanding. If ever a problem arose, Cullen was always available to take our call, and always able to solve the problem with a minimum of fuss.

The end result was quite spectacular, and we cannot speak highly enough of Cullen and his team at PPL.”
