LEFF – A Leader in Green and Sustainable Building and Remodeling Practices

Founded in 1978 by David Leff, the company established itself as an early adopter of green and sustainable building processes when it built the first solar multi-family project in Cotati, California.

During the 1980’s, David and his father Irwin Leff continued to develop and build environmentally responsible and resource-efficient residential subdivisions. At the same time, they began to increase their focus on building and remodeling for local homeowners. Custom home-building and remodeling brought a new set of challenges: how to help clients discover the problems with their home and then design and build beautiful and functional solutions efficiently and cost-effectively.

Meeting this challenge over many years is what has formed the Leff Design Build process and defined their core mission: to make every project a superior client experience. LEFF’s approach makes their entire Team of architects, designers, estimators, project managers and field crew accountable at every step of the project. The team welcomes every client and includes them as an essential element of the process. Communication and accountability between all parties is transparent and consistent. The result: a custom project delivered on time and on budget, and very happy clients.
