About The Team

Granoff Architects, established in 1989, is a full-service design firm dedicated to providing outstanding client service and achieving excellence in architecture.  We have a staff of over twenty professionals, with offices located in Greenwich, CT.  We work on a wide variety of projects in four integrated disciplines:  residential architecture, commercial architecture, landscape architecture and interior design.  Our design philosophy is balanced between respect for the past and excitement about the future, which has resulted in work of great variety, vitality and enduring quality.

At Granoff Architects, “green” design is an essential part of everything we do. It is our philosophy to incorporate human-centered sustainable design principles into all of our projects. Strategic building orientation and site design, alternative energy systems and a high-performance building envelope can reduce energy consumption significantly. Specifying recycled and “healthy” materials minimizes the impact of our projects on the earth’s ecosystem.  As LEED-accredited professionals, we have extensive experience with solar energy, geothermal systems and high-efficiency lighting. Our sustainable design philosophy employs cost-effective and practical solutions that not only conserve energy, but also make our buildings healthier places for people to live and work.  As leaders in the field, Granoff Architects offers our clients all of the opportunities and benefits of “green” design.

•Allows moisture to escape quickly before it damages the sidewall materials
•Protects the wall assembly from the deteriorating effects of mold and rot
•Reduces the chances of premature peeling or blistering of finishes
•Prevents damage from surfactants by separating the cladding from the water resistive barrier
•Saves time and labor costs by eliminating the need for furring strips

Invention of STYROFOAM™

In 1941, Dow invented a process for extruding polystyrene to achieve a closed-cell foam that resists moisture. Recognizing its superior insulating properties, buoyancy and "unsinkability", it was originally adopted in 1942 by the U.S. Coast Guard for use in a six-man life raft. That was the start of many other wartime applications by the Coast Guard and U.S. Navy.

Even in the early 1940s, the spirit of the Human Element was exhibited by the Dow research chemist who invented STYROFOAM™ Brand Insulation.
