We did an extensive house reno in the Moore Park area involving some complex structural features, including whole roof re-design, underpinning the basement, and used a few sizeable steel beams throughout the house. We used YCL Structural Design for all of our structural Engineering needs and were very pleased by the work done. Yu Ching was very responsive, professional, and provided a few great structural solutions to our house which improved the layout of our house. I would definitely use him again and would highly recommend his services to anyone.
