What our customers say about us…….

I cannot adequately put to words how pleased I am with the finished product. This has made a great improvement to our lives. Cannot recommend enough.
— Mr & Mrs J – Single story rear extension.
Chris and the guys have done a great job. Experienced and knowledgeable team. We were kept informed of issues as they arose (which you always get when extending an existing building) and Chris was very proactive in coming up with practical and cost effective solutions. There was a continuity of attendance on site despite inclement weather, and the site was kept clean and tidy. Delivered on budget with agreed extras. We would use Chris again and I can highly recommend Brownstone for your project.
— Mr & Mrs D – Single story side extension.
The team at Brownstone continue to deliver high quality workmanship on schedule time and time again. This is now our 4th project working together and I hope this working relationship can continue on our future projects.

Chris and his team were recommended through a friend who has worked with him in the past and assured us of his work and reliability, we were not disappointed. Chris went beyond his role of employment as our project/site manager and builder. He came with us to choose materials and spent his personal time helping us go through finances to make sure our new build home came in on budget. The quality of his work from the footings to the final finish was impeccable and we would have not achieved the build of our beautiful family home without him. A true professional builder, of which we are very grateful and would recommend him to anyone we know.

— Mr & Mrs W – Single story front extension.
I would like to thank you and your team for constructing an outstanding facility, on time and to the standards required. It was very beneficial to have your subject matter expertise input. The facility is already proving to be an excellent venue, which is laying the basic skills of firing from realistic and demanding pieces of cover for our young soldiers. I would strongly recommend your company for any future work in the barracks.
I wish you all the best with your company in the future.

Outstanding attitude and work ethic from Chris and his team. Proactive and knowledgeable in dealing with design matters and all other decisions. Very fair and reasonable dealing with all financial matters. Will be using again in the future and will be strongly recommending to others looking for work to be done. Great service.
