I found GL Design online, as a company that was local to me that would support the structural... designs for our renovation project. With this being our first renovation, I don't mind admitting that I didn't really know what I was doing. As I talked Gregory through what we wanted, he was patient and knowledgeble and made me confident he knew what was needed, whilst providing us with helpful alternative options with the value of his experience. Their price was fair too. I'd have no hesitation in recommending GL more

We had some concerns about some structural elements of our home and asked GL Design Services to... complete a review to let us know whether any work was needed to bring them up to scratch. Gregory was excellent from start to finish, he was very knowledgable and took time to explain things to us and present the different options for correcting them. He also drew up very detailed plans within a reasonably short timeframe so we could start approaching builders. Even though their quote was not the cheapest we would have no hesitation in recommending GL Design Services, they're worth every more

RE: House extension in Coulsdon, single and double storey.Gregory has been an exemplar structural... engineer. His quotation was not the cheapest but reasonable. From speaking to Gregory, I feel that he is knowledgeable and understands my needs. Once instructed, Gregory visited the site and took details necessary for his work. He worked effectively and was able to produce the calculations and specs required for the work in a timely manner.I would not hesitate to engage Gregory for further work in the future. If you are in London and the South East, do not hesitate use GL Design Services for your structural more
