Spiral Glass Stair, Boston

This spectacular two-story stair contributes to the open and light feel of this waterfront residence on Battery Wharf in Boston Harbor.

TriPyramid worked with the architect and structural engineer to develop the design and details for the full stair system. TriPyramid’s 3D digital model was essential in the precision-forming of the heavy, stainless pipes which act as the “spine” of the structure. The model was also used by the glass manufacturer to fabricate the treads and balustrade panels.

The stair frames were delivered to site in two sections, easily lifted and bolted into place, ready for installation of the glass. TriPyramid also provided the stainless steel fittings used to fix the balustrade glass and the treads, and the stainless steel handrail.
