1SA DESIGN + BUILD
ONE-OF-A-KIND ARCHITECTURE
1SA /ee-sa/ is a name which is rooted from the word “ISA”, a Filipino word for “ONE”. Our goal for every project is to design a One-of-a-Kind Architecture through the synthesis, or coming together, of fresh, innovative ideas and solutions to create one unique and fitting concept for every project, which each client can say is uniquely theirs.
Our Mission
One with Clients
We value client dialogue. We collaborate with our clients, users, and end-users in developing ideas and solutions that are suitable for every lifestyle and set of needs.
One with Natural Environment
We embrace biophilic design. We design in consideration of the existing natural environment of each project, where we connect the users and its surrounding natural environment through architecture.
One with the Goal
All of these are to realize our one goal, which is to create one-of-a-kind works of art through architecture for everyone to enjoy.
