Estes Twombly + Titrington Architects

79 Thames St.
Newport , Rhode Island 02840
Phone: (401) 846-3336

Estes Twombly + Titrington’s work consists of simple, innovative designs with firm roots in the New England tradition. We approach programs and problems with the belief that the best solutions are logical and direct, that a good design will appear inevitable.

After years of work on renovation and new construction projects in the northeast, our design aesthetic has evolved into a quiet modernism based on traditional methods and materials, with a sensitivity to local site and climatic conditions. Through careful siting and design, we can break down the usually solid wall between indoors and outdoors, extending the warm seasons and providing natural heat and ventilation, in spite of the rugged New England climate.
