Since 1996 Sunrock has been building well-designed, distinctive residences throughout Metrowest. Working closely with a dedicated team of design professionals and experienced subcontractors, Sunrock strives to build extraordinary homes blending form and function to create a highly attractive and comfortable living environment.

Each home’s floor plans are custom designed to create a flexible layout offering both formal and casual spaces well suited to a variety of family lifestyles. Attention to detail and superior craftsmanship are hallmarks of Sunrock homes. Whether it’s preserving a view in locating the house or incorporating custom millwork into a coffered ceiling, there is a continuous effort to construct each component of the house to the most discerning standards.

Sunrock also has proficiency in obtaining comprehensive subdivision approval having successfully navigated the approval process for several subdivisions, including Magnolia Farms, a 34 lot development in North Grafton, MA.

Considerable thought was given to minimizing traffic and environmental impact to the surrounding neighborhoods.

In each acquisition, Sunrock seeks to create value for its investors by creatively renovating and repositioning each asset whether for sale or lease.
