    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.

    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.

    One Design helped our project in London in 2023. Their surveyor nailed the details right from the start, giving us a clear picture of what we were working with. And the architect brought some incredibly fresh ideas that genuinely transformed the space. What stood out to me was how well they worked together, blending thoroughness with creativity. The place looks fantastic now, way beyond what we'd hoped for. Would love to team up with them again. They just get it.
