Architect Morris Adjmi talks about The Sterling Mason building. This 115,000-square-foot project in Manhattan’s historic Tribeca neighboorhood features 37 luxury condominiums. The 1915 brick and terracotta warehouse at the corner of Laight and Washington Streets has been restored and paired with an aluminum-clad identical twin, as though a photographic negative of the older structure. The center of the seven-story building was removed to create a landscaped courtyard, giving most units both street and interior views.
