Sugar Hill Residences


Project Description

This new 13-story 172,665 sq. ft. structure contains 124 residential units, a daycare center, a museum, offices, rentable commercial space and one level of below-grade parking. The affordable multi-family residences are a mix of studio, one-, two-, and three-bedroom units. The building incorporates green design principles emphasizing environmentally responsible materials and energy saving technologies to minimize operating and long term costs. The building is designed to achieve a LEED Silver certification.


The diverse mix of uses includes outdoor courtyards, terraces and a green roof garden with each of these areas dedicated for use by either the residents or one of the building’s other tenants. The building’s saw-tooth plan is constructed utilizing a reinforced concrete superstructure clad with architectural precast fa├žade panels. The unusually shaped building is located on the ridge of Sugar Hill in Harlem and offers dramatic skyline views from a majority of its residences.

Challenges and Solutions

Mountco was selected as the general contractor for this complex structure following an extended analysis of the project’s design, pricing and scheduling requirements. The site is constrained by being on the corner of a dense urban neighborhood and by having a four level, below grade, NYC subway tunnel bordering one edge of the property. Extensive rock excavation, shoring and underpinning of adjacent existing buildings was also required to accommodate subsurface areas of the new building.

The vetting and selection of experienced and well-established subcontractors and careful planning of the sequences of work by the many different trades were crucial to the efficient integration and steady flow of the construction process. Mountco’s extensive relationships in the industry and their experienced staff of construction professionals were able to move this project from the bidding and contract award phase into the construction phase in a timely and effective manner.
