Highlights
"Our building extension done by One Design was impressively handled, blending the original structure with modern updates perfectly. Great thanks to Lei and his team. I would not hesitate to recommend them."
"The architect brought a masterful touch to the project. Thanks to a keen eye for detail and space."
"I believe every family in need of house renovation shares the same anxiety as us. The overwhelming flood of online ad makes it difficult to choose. We were fortunate to choose them (sometimes you need to trust your intuition), sparing me the hassle of finding someone for each project. The initial delay due to their busy schedule left us waiting for a little bit. However, the end result was satisfactory. They were indeed very professional, and the pricing was reasonable."
