Walsh Construction led this renovation project that modernizes and preserves affordable apartment units. Lawson House, built in 1931, was the largest single room occupancy building outside of New York City with 583 rooms. The rehabilitation of the historic 200,000-square-foot, 24-story apartment complex transforms the building’s single-room occupancy units (SROs) into over 400 affordable apartment units with private kitchens and bathrooms. The project is designed and constructed to achieve LEED Gold certification.
