Modular Feature Stair – Bethesda MD, USA


This project was completed for a prestigious private equity company headquartered in Bethesda, MD. Synergi worked with world-renowned architect Dennis Austin of Rogers Stirk Harbour + Partners to successfully design, manufacture, and install an incredibly eye-catching, floating modular feature stair. The staircase connected the three floors of the existing office building. The striking design utilizes a combination of glass, stainless steel, and a high gloss paint finish, creating a central sculptural element, allowing the free flow of light and easy access between office areas. In addition to the creative design, engineering expertise, and specialist manufacturing capability required, a key challenge of this project was the requirement to install the staircase in a fully occupied space. This had to be factored into the whole design process and required minimum disruption to the tenants, and of course, strict adherence to health and safety regulations and the project timeline.  The result is well worth it, winning a prestigious WBC STAR Award.

Scope of Work

Design, Manufacturing, and Installation of a Three Floor Floating Feature Stair

  • We used a creative combination of glass, stainless steel and high-gloss paintwork, carefully lit with display lighting, to create the impression of a sculpture encased in glass – a striking central point in this high specification office

  • The curved central landing features are supported by a suspended harness system of rods and spars. Both technically and visually excellent, the curved design elements include the stainless steel handrail and glass balustrade

  • Specially requested by the designers to be ‘like the paintwork on a Lamborghini’, we commissioned a bespoke automotive paint to provide a smooth, high gloss, fluorescent orange finish

  • The balustrades for the stair and adjacent balconies are comprised of a glass panel point-supported system attached to outrigger arms, to further accentuate the floating impression.

  • The exposed fixings and stainless steel components show the incredible attention to detail and immaculate finish. Stunning in their own right, when proudly expose alongside the other high-spec elements they show the functional beauty of the overall structure when viewed from both near and far

  • Supported on inset stainless steel between stringers plates, the glass treads and landings are reassuringly solid and adorned with a subtle etched pattern
