Burlington Associates was chosen to design the new cathedral; architects Thomas Cullins and William Henderson led the project.

[2] A good example of Brutalist architecture, St. Paul's Cathedral is built of exposed poured-in-place reinforced concrete, featuring a coffered sanctuary, textured surfaces from vertical formwork, and carefully proportioned and patterned joints.

[4] The interior finishes include white oak furnishings and acoustic paneling and a slate floor.

It is naturally lit from the skylights and a large curtain wall, which provides a view of Lake Champlain and the Adirondacks.

A ninth bell cracked in the fire and is now at the foot of the tower, adjacent to the Memorial Garden gate.
