Babraham Research Campus, Cambridge
Spiral UK created three steel helical staircases for a research and development building at Brabraham Research Campus, a development of laboratories and offices near Cambridge whose purpose is to support early Life Science companies.
The external fire escape stairs make an impact through their complicated curves resembling DNA which mirror the undulating shape of the building roofline. At night the LED lighting to the curved balustrade gives the clever effect of glowing threads of DNA, very apt for a research campus.

Double storey helical staircase
This large external steel staircase was an unusual choice due to its helical design. The double storey flight had two landings and was made in durbar plate with a satin polished stainless steel balustrade. The handrail had LED strip lighting fitted to the underside.
The staircase was fabricated in mild steel galvanised to BS729 and powder coated to a RAL 7012 (Basalt Grey). As with all our fire escape stairs these were compliant with British Standard BS5395 Part II (Code of Practice for the design of helical and spiral stairs 1984).
