The foundations of yhsA were established in 2001 under the sole proprietorship of Yap Hock Seong Architect. Since then we have grown into a medium-sized practice with two partners and eighteen employees.

At yhsA, we approach design in a holistic manner, collaborating with key movers and stakeholders in the early stages of each project. Our design innovations are aimed at enhancing and uplifting human living. This is achieved through thorough understanding of the context and the users’ needs. We also strive to optimize both the functions and aesthetics within the same building, a process which we apply rigorously from concept to detail design.

We have considerable experience in high-density residential projects, and have also enjoyed designing commercial and institutional buildings. We also provide master planning services, especially for high-density developments as well as projects located on steep terrain.
