Built in 1955 for civic activists Stim and Kay Bullitt, the modern H-shaped residence at 1125 Harvard Avenue E broke Capitol Hill tradition with its innovative A-frame design, radiant-heated floors, and unique skylights. Designed by Fred Bassetti to reflect Stim’s love for the outdoors, the home featured soaring vaulted ceilings, a massive stone fireplace, and expansive grounds landscaped by Eckbo, Royston, and Williams. For over fifty years, this informal family estate served as a vital progressive hub, hosting historic political meetings like the Keechelus Group and legendary summer picnics that united Seattle's political and social elite.
The home was built on the former Henry mansion site in Seattle’s historic Harvard–Belmont district, the Bullitt House is carefully integrated into its landscaped setting between Lake Union and Volunteer Park. Mature trees, gardens, and a covered approach create a sense of privacy, while the house’s partial daylight basement responds to the sloping site.
The residence is organized as an H-shaped composition of three volumes: a dramatic post-and-beam A-frame wing, a central entry pavilion, and a bedroom wing. Large glulam beams, a steep roof with translucent ridge panels, deep overhangs, skylights, and expansive windows emphasize natural light and structural expression. Exterior materials include vertical tongue-and-groove wood siding and Welchboard plywood panels.
The A-frame wing contains the home’s signature space, a soaring living and dining room with tall gable-end glazing, an open loft, and a freestanding circular fireplace set against a stone wall. Exposed beams, slate floors, custom wood detailing, and strong connections to the surrounding landscape exemplify the home’s warm mid-century modern design.
