From the start Michael was upfront regarding drafting costs and Council fees. Our rough outlay was discussed and Michael listened carefully to our ideas.  The plan was drafted to gain the best aspect on our land. Michael’s knowledge, along with his friendly and accommodating manner made the whole process enjoyable and stress free. We have already recommended Blue Mountains Building Design to family and friends.

Michael Keightley recently helped us with an application to extend our house. He helped us in the concept stage, was very understanding of our needs, and gave good advice on how they might be met. He then drafted the plans and prepared all the documentation to lodge with Council. The application was successful and there were no queries from Council. We were very happy with what Michael did for us and enjoyed working with him as he was always pleasant and co-operative. We are pleased to recommend him to anyone who needs similar work.

Michael from Blue Mountains Building Design was a great help in putting concepts into working drawings and Council Applications for a number of my projects. Michael was always very professional and an effective problem solver. Michael went beyond the basic requirements for a draftsman and I would not hesitate to recommend his services in the future.

Michael Keightley provided an extremely professional approach to an extension I carried out in Hazelbrook. Nothing was a problem, very easy to talk to and was very helpful with questions I had towards the job. Will definitely use and recommend Michael again. Thanks Michael.

I engaged Michael Keightley to develop plans and for a new garage at my property in Blaxland. The service was prompt and highly professional. I received the plans ready to submit to Council and had no issues relating to the plans in gaining council approval. I would recommend this service to anyone.


Michael was found for us by our builder. We all met, he knew exactly what we wanted and made good suggestions when we had trouble visualising other aspects. He produced our plans very quickly and efficiently, did the arrangements with Council and followed up with Council so that our plans passed without a hitch and no stress. We were very happy with Michael’s work and would recommend his services. He planned a lovely addition to our home.


Michael drew up the plans for my small extension in Woodford. He was friendly and helpful from the get go and gave excellent advice, He offered to make himself available for support even after the plans were through Council, nothing was too much bother. He dealt with Council and the Bushfire Agency rules and regulations providing me with a worry free result.  Each builder to whom I showed the plans, during the tendering process, voiced how impressed they were with them and asked who had drawn them up, As a novice this was confirmation for me of what a good job he had done I would not hesitate to use Mike again and have already recommended him to others.

Michael helped us design our new home in Leura. He knew what we wanted from the get-go, and innately understood our style and needs. He provided simple solutions for problems we encountered on the site. As first time home builders, Michael easily guided us through a somewhat daunting process and created exactly what we wanted from our fledgling ideas. Very professional service and communication. We’d recommend him to anyone thinking of building or extending.

Mr Michael Keighley of Blue Mountains Building Design recently completed the plans for our house extensions. We were both very impressed with his professional skills and capacity, his prompt completion and submission of the plans, and his caring and friendly approach. The plans were approved without problems. We could not recommend him more highly.
