Designed by Philip Johnson, the house at 9 Ash Street was his Harvard University Graduate School of Design (GSD) thesis project. He studied modularization and used prefabricated wood-framed panels for the home’s floor, walls, roof, and integral perimeter fence. Completed in 1942, the residence quickly became a renowned gathering place for the local architectural community. In 2010, GSD purchased the home, which had fallen into disrepair and experienced a partial floor collapse after decades of private ownership. SGH served as the structural engineer of record and building enclosure consultant for a two-phase stabilization and renovation of this iconic modernist house.
