"We had a loft conversion done, with one bedroom, one bathroom and a storage space. Also we had a formal lounge which was an open-plan design, Rick's team enclosed it and added French doors. Rick and his team were very professional, punctual and extremely well organised. The job was done in about half the time that was originally estimated as Rick did such a good job of co-ordinating the various tradies. Rick always responded to missed calls and messages, and when he said he will do something he always got it done. Rick also managed to spot a few places where we could save money on the job. We are extremely please with the job done by Cornerstone and have recommended them to everyone who has asked. We have had a lot of fun showing off our new loft to visitors :)" 23rd February 2015 11:38 pm -MandR

"15sqm Loft storage room. A difficult build due to the structure of the roof. Rick and his team inspected the site a number of times prior to providing a price to ensure it could be done. We were briefed on what would be done and the approximate timing of the project. The team were very focused on the project and completed the work quickly, while being mindful and courteous of our family. Issue that arose were dealt with quickly. The room is light an airy, with windows, down lights & power, and following completion, we were supplied with all warranties and structural plans for the project. We are very happy to have completed and being able to use the loft. Thank you Rick and Team." -2nd September 2014 11:13 am Anonymous Member

"Rick came out and gave us a quote on enclosing our carport into a room. As his quote was the cheapest and he was willing to do the job as we wanted it done, we went with him. The main tradesman who worked on the job was professional, always cleaned up, here early and on time, worked quickly and was a really nice man. Other tradesman who came to the house were very professional. Any concerns we had was sorted out quickly by Rick and the finished product speaks for itself. We now have an extra room on the house for our son and we are very pleased." 1st September 2014 10:53 pm Athenaw

"I got Rick out to provide a solution for storage space in our roof. He took the time to discuss several options and listened to what our needs were for the space. His final recommendation was to build a simple loft storage only space of about 9.5 square metres. This was not the most profitable option for him but was the most suitable for us! His tradesman were clean, friendly and professional. I was really impressed!" 31st August 2014 4:06 pm ruthh6
