Private seafront residence, utilising a slender steel and glass structure to meet an architectural brief that maximises views out to the ocean.

This private residence is situated in a secluded area of Long Island with uninterrupted views of the nearby ocean, offering six bedrooms and spanning across four floors. The architectural intent for maximum transparency presented a number of environmental challenges. The location is a hurricane prone region and one of the most corrosive localities in the country. The design of the building comprised of a slender and significantly exposed steel and glass structure.

Eckersley O’Callaghan has engineered a double-height open living room resulting in two stability systems – each of which employed a steel braced bay as well as a structural concrete chimney. Full-height stainless steel mullions and impact resistant insulated glass units enclose the majority of the building. Providing a stiff roof diaphragm and accommodating both vertical lateral deflections was paramount.

The client required full integration throughout the property. We designed the staircases at each end of the building and the elevated interior bridge in tandem with the primary structure.

We were able to conceive a system that limits human induced vibrations while maintaining a slender aesthetic. Full height, 37-foot pre-tensioned cable walls were adopted to act as a guard through the center of each staircase. A springboard base maintains pre-tension as it supports the roof.
