Kasten Builders ethics, standards and quality craftsmanship remain uncomprised


Across the Golden Gate Strait from San Francisco, beautiful Marin County boasts Golden Gate Bridge Views, the sprawling Marin Headlands, rolling hills, and abundant outdoor recreation. Marin County’s proximity to San Francisco combined with its many small, family-friendly towns with room and space to grow make this place extra special. Kasten Builders has built and remodeled homes in Marin County for many years.

Sonoma County is well known around the world for its rolling, grape-vine blanketed hills but those familiar with the area know that this place boasts more than wine and beautiful views. This coastal county is the perfect spot to purchase acreage and build your custom dream home. 

San Francisco is arguably the cultural epicenter of California. As the second-largest city in Northern California, San Francisco is at the forefront of arts, culture, and technology. While there aren’t as many lots for sale as there are in the counties surrounding SF, there are many stunning, classic homes built in the early 1900s with history and good bones. 

Just across the San Francisco – Oakland Bay Bridge from SF, Alameda County is home to major California cities such as Oakland, San Leandro, and Fremont. With shoreline on the San Francisco Bay, Alameda County boasts city, ocean, and mountain recreation. 

Our firm’s culture is not saddled to a single, predetermined style. We provide our clients with outstanding service and work with them to establish a program that achieves their unique design expectations and honors their budget.
