The Project
Three-building residential development consisting of the restoration and conversion of a historic 1920s industrial building and two new wood-framed buildings with a below-grade parking garage. The project also included stabilizing and underpinning an iconic 100-feet tall masonry smokestack as well as preserving a single-story historic façade along Lamont Street and incorporating it into the new building. The existing four-story, industrial concrete frame building underwent extensive concrete repairs primarily on the exposed exterior beams and columns. The building was converted into condominiums with a new landscaped terrace and mechanical area on the roof, new interior stair and elevator core, and a new below-grade mechanical basement. The two new buildings are four and five story apartment buildings with the eastern building incorporating a row of loft units behind the existing historic façade along Lamont Street. The new 5-story building has an amenity penthouse with roof terrace and green roof features.
Structural features
The new apartment buildings are wood-framed with open-web wood floor and roof trusses and wood stud bearing walls. Steel beam and columns transfer out bearing walls at the ground floor to create large open amenity spaces. The below grade parking level is cast-in-place concrete. The existing column footings along the abutting side of the 1920’s building were lowered to match the deeper garage excavation. The historic 100-feet tall smokestack at the east end of the property was stabilized and underpinned to extend its foundation bearing below the new basement level. The 1920s industrial building was heavily modified to repair years of damaged concrete on the exterior due to rebar corrosion and spalling, new floor openings and a large light well on the east and west sides were created in the structure, and the roof slab and other select elements were strengthened using supplemental, external reinforcement to increase the load-carry capacity to suit the new use and support the new openings.
