We selected Hallmark after a careful and extensive research of eight building contractors. Our main requirement was a trouble free project with no adverse surprises or hassles over trivial variations. We can honestly say that Hallmark delivered on all fronts. Hallmark’s tradespeople were all obliging, friendly and highly professional, a pleasure to have around. In particular, where last minute modifications were considered, we always received a ‘can do response’. All things considered we were happy with the way in which our project was managed and delighted with the final result.

Hallmark Developments WA built our granny flat following a rave review from friends of ours. They certainly didn't disappoint, producing a high-quality build at a reasonable and fair price. Mark is a highly ethical person who takes great pride in his work, and he and his team were easy and pleasant to work with. Lots of our neighbours have said how beautifully the granny flat blends in with the main house and looks like it has always been there. Wouldn't hesitate to recommend Hallmark Developments!

Huge thanks to Mark from Hallmark Developments for building our new granny flat. The end result is more that what we hoped.
All of your tradies did great work and watching our backyard transform has been amazing.
Thanks again,

Mark and the team did an amazing job the granny flat looks fantastic!! During my search, I met with about 5 different builders – I knew nothing about any of the companies but as soon as I met with Mark I knew he was the one for the job, sometimes you just have to take a leap of faith! Every day the guys were onsite and worked non-stop – they even put up with all my questions and constant changes – lucky for me the tea and biscuits worked. Building the Granny flat was probably the best decision we have made. We still get local passers-by commenting on how fantastic it looks and what a great job the builder did! We would have no hesitation in recommending Mark and the team to anyone, in fact we already have! Thanks again guys...
