Alcon Builders Group has created a new luxury townhouse in Tribeca that combines a complete interior redesign of a landmark-status, two-story 1915 brick building with new construction of an adjacent six-story, steel-framed, fiber and cement tower.

“This perfect marriage of old and new is living proof that a building can feature every smart, state-of-the-art aspect of today’s technology without sacrificing character, style or warmth,” says Patrick Boland, president of Alcon Builders.

To maximize the use of natural light, the building features a new glass curtainwall facade composed of ultraviolet, heat-resistant, laminated, high-efficient, low-E glass. For the renovated two-story structure, double pane thermal windows were custom-cut to fit the space of the original arches. A pair of oversized skylights also flood the original building with light.

The single-family, mansion-like property comprises more than 11,000 interior and 1,500 exterior square feet between the two buildings and includes five bedrooms, seven full baths, four powder rooms, three fireplaces, a staff apartment, an artist’s studio, a grand library, a screening and billiards room, and a private outdoor dining atrium.
