"John (and Hatheway Architects) guided us through every step of an indoor and out 3,500 sq ft gut renovation project of our second home. Not only did John help us select and purchase a two story mid-century modern, he supervised the construction rebuild contract, design, and budget process... John worked closely with us to help select the general contractor, vendors, appliances, lighting, floors, tiles, woods, counters, cabinets and finishes. The two years we spent on this project proved very rewarding and satisfying."

— Ken Hochman, Connecticut Home Owner
