“We chose Michael Aubrey structural engineers as they were local.  We were provided with structural drawings with some design ideas for the porch and documents were submitted to the Building Regulations and Planning Offices on our behalf.  We really liked the honesty and commitment to the timescales and the customer service from the start was fantastic compared to other firms.  The design discussions for the porch were free flowing and we felt very much the priority.  Leigh-Ann, Oliver and Andy were great to work with, with great communication to us, the client.  We found the whole process very seamless and the drawings were of great quality and the additional discussions over the design element of the porch was very insightful and gave us different perspectives on the design ideas.  We felt that for this project, Michael Aubrey structural engineers were very good in every aspect and we would recommend their services.”
