Case Studies

Le Petit Fort, Jersey

Spiral UK were commissioned to create the feature helical staircase, concrete spiral stair and external straight stair for this unique residential property on the west coast of Jersey, a stone’s throw from the island’s spectacular beaches.

The property was designed with two accommodation wings around the central feature helical stair.

The awesome natural setting and the thick granite walls of the property inspired Spiral UK to create a luxury staircase design that fully complemented its surroundings.

The property was a Channel 4, Grand Designs featured project. The architectural design was the winner of the RIBA Regional Awards 2016 and was on the shortlist for House of the Year 2016.

The feature helical staircase

The dramatic helical staircase is a real feature of the property and fits perfectly with its interior style. Providing access to the living spaces on the first floor, this bespoke staircase has beautiful oak treads, risers and handrail. The stair was created out of Corten steel, which was left to weather outside before being installed, bringing a sense of the building’s external materials inside.
