Helios Design Group - Architecture, Interior Design, and Planning Chris Hosford and Carol Marsh began their architecture firm Helios Design Group in 2004.

The heart of our work is creative problem solving, from the siting of buildings to the most graceful angle for a sill. We listen carefully to our clients, making sure we understand your needs and dreams, and bring to bear our years of experience with different ways of looking at a problem. All part of design. We work on residential projects from the tiny to new housing developments, and on select commercial projects. Architecture draws out interest at every scale.

A kitchen can be warm, functional, clean, and minimalist at the same time. Painted white bases and uppers, terminating into a walnut appliance and storage wall, accentuated by white marble with gray veins that wraps the room.

Old school vs. new school.

A work in progress. A soft color palette kind of reflects the moody morning winters we have here in New England. But nothing prevents us from adding a little colorful activity on the ground.
