Tripartite stewardship: community, building, and environment

Originally designed by H.H. Richardson in 1877, Trinity Church is regarded as one of the most significant buildings in American architecture. In a true partnership forged over two decades of collaboration with the church, Goody Clancy orchestrated a multi-phase renewal that preserved the structure’s architectural integrity, dramatically improved the quality and quantity of its gathering spaces, and enhanced the building’s accessibility and energy performance.

Through a two-year comprehensive building assessment and planning phase, which involved 90 different interest groups, we identified a five-phased approach to Trinity Church’s renewal.
This decades-long renewal has truly been a community collaboration. The ideas of nearly 100 different interest groups–including historians and international conservation experts–helped inform our work and build widespread consensus. Headshot of Jean Carroon with blue background

Over 12,000 SF of space was excavated to create the Undercroft, a flexible new community gathering and meeting space.
Project impact
  • 100%

    Of stormwater is managed on site and distributed to maintain ground water levels essential to the structural integrity of the wood pilings

  • 1,500 ft

    Deep wells were dug into the bedrock to fuel a new geothermal energy system that heats and cools nearly 30,000 SF of space
