About KR Sustainable Structures
A woman- and AAPI-owned full-service general contractor rethinking how building gets done.
-
We don’t just use green building materials. We invent them. Founder Kathy Rai holds two patents for Titancrete™, an innovative material that is rot-resistant, fire-resistant, and earthquake-resistant. Cut energy use up to 42%.
-
We proactively think about who’s not at the table and ensure the right people are in the room. We see projects holistically, listen actively, and communicate effectively. This inclusive approach helps us deliver exceptional work on time, on budget.
-
Over 20 years, building operating costs reach ~20% of home value. We consider what it’s like to live, work, and play in the buildings we create. Green approaches recoup higher up-front costs within 3–5 years.
