Chengdu Longji — Outdoor Single-Stringer Cantilevered Staircase
An outdoor spiral staircase for a Chengdu Longji residential development. The site draws from Tuscan and contemporary art influences — textured stone cladding, garden landscaping, a setting that feels grounded and unhurried. This staircase was conceived as a sculptural element: a piece of contemporary design set against a classic estate backdrop, the two in deliberate contrast.


The curve is relaxed and open, suited to an outdoor courtyard setting. Timber balustrades reference the building’s rustic, heritage-inflected character. The main structure is a single steel stringer; the treads combine a steel plate base with laminated tempered glass inserts — warm natural material alongside a clean contemporary finish, layered without competing.
The single-stringer cantilevered structure with glass treads avoids the visual weight of a conventional base, keeping the garden composition uninterrupted. The glass reads as light; the structure holds firm.
For outdoor exposure, every component is treated for the environment. The steel receives a multi-coat anti-rust finish. The timber balustrades are pressure-impregnated against moisture and decay. Both are built for long-term outdoor performance. durability.
