Carol Marsh, AIA – Principal
Carol spent time in her youth dancing, writing, making art, and enjoying the waves on Venice Beach in California. She was doing ceramics when she discovered architecture, with so many of the same concerns at a larger scale – form, function, beauty, inside and outside. Carol studied architecture at the University of Southern California, and has worked for several architectural firms doing residential and institutional projects. In her twenty years of experience in architecture, she’s come to love solving puzzles, architectural and other, and helping folks to make their dreams real.

Chris Hosford, LEED AP – Principal
Chris’s first love was figuring out how to make things work. He spent a decade as an engineer, when he wasn’t driving a van for his wife’s rock band. Architecture gave him a broader palette. Now he figures out how to make places work – for the way people live, the materials of building, and the environment. Chris studied engineering at U Mass Amherst, and Architecture at the Boston Architectural Center. He and Carol opened the doors at Helios Design Group in 2004, after having worked together for several years at the Boston architecture firm of Hickox Williams Architects.


Other Plans by
Carol Marsh &
Chris Hosford


We highly recommend that you click on two boxes – the number of bedrooms you know you need, and one less bedroom. For example, if you need 4 bedrooms, click on the boxes next to 4 and next to 3. Otherwise you will not see homes where existing rooms on the lower, main, or upper levels might work perfectly well as a bedroom instead of as an office, study, etc.
