    Calculations and documentation for structure alterations

    We've just carried out some renovation works including the removal of one load bearing wall, and an opening in another wall previously dividing dining room and leaving room. Sai helped us with the works providing calculations for the the new structure, and all the documentation required by Building Control to approve the works. We are very happy with the works, the service was great throughout the project, and the price was fair. Thank you Sai!

    Professional, Prompt, and Excellent Value

    I hired this company to carry out a structural survey to determine whether a wall in my property was load-bearing. The service was excellent from start to finish. He arrived on time, worked efficiently, and his pricing was very reasonable compared to other quotes I received. The report was generated promptly and was extremely useful, providing clear and professional guidance that helped me move forward with confidence. I would definitely recommend his services to anyone needing structural advice or surveys. Thank you for a great service!

    Structural works - load bearing wall removal - drawings, calculations and specs for steel beam

    Sai was absolutely brilliant and had a quick turn around time for his works. Very familiar with the nature of the works, building regs and approval process by the council. In addition, he was very helpful when we had the builder around and had questions on the steel beam being put in. We will be going back to him in future for other works. The current work being done was to demolish a ln internal load bearing wall which included installing a steel beam. Sai provided all the design drawings and calculations required to complete the works and was readily accepted by the council.

    Amazing service!

    We reached out to Pro Structural Design ahead of completing a loft conversion at our home. Sai promptly responded to our initial enquiry, setting up time for a telephone call and then a meeting at our home. Sai was prompt and polite in replying to my husband’s never-ending questions, providing clear answers to detailed and complex enquiries. The outputs were to a high standard, and competitively priced for the area. We would not hesitate to recommend Pro Structural Design to anyone looking!
