il NIDO Designs is a San Francisco based general contracting firm. We build structures to last by adopting the latest in building science and technology to ensure the buildings stand up to the elements and the test of time. We want our homes to integrate into their environment and believe in implementing green building technologies whenever possible. We are also admirers of great architecture and see the best in well thought out spaces and executed details. We strive to bring those principles into each and every project we work on.
