This staircase inserted into a terraced home in London characteristics alternating treads that make the most of a tight area, and perforated steel surfaces that permit light to filter by way of.
Neighborhood firm DBLO Associates designed the staircase as portion of its refurbishment of a top-floor flat in a Georgian terrace on Redcliffe Square, Kensington – a stone’s throw away from the yellow brick townhouse completed by TDO earlier this 12 months.
It connects the two-bedroom property’s renovated roof terrace with a landing at the prime of the primary stairs, which the architects re-clad in timber as component of the project.
The original access up to the roof terrace was provided by a steep staircase with narrow treads that made it awkward to set foot safely on each phase, specifically when descending.

“The project was about upgrading the staircase to make confident it met existing laws and was a whole lot much more usable,” project architect Claire Hale informed Dezeen. “Simply because it is an internal stair, the concept focused on getting daylight down into the existing staircase below.”
The narrow void amongst the landing and the opening to the roof meant the only way to satisfy arranging regulations – while also creating actions that are deep ample to use comfortably – was to devise a resolution with alternating treads.
A entirely glazed enclosure at the best of the stairs replaces the earlier solid walled passage and includes a door that opens onto the terrace.
The glass construction allows more light to reach the interior, which the architects accentuated via the choice of perforated metal for the stairs.
“We wished to make a extremely lightweight framework that is perforated and lets light flow down into the flat,” extra Hale. The material’s transparency also retains views from the landing in the direction of rooms behind.
As an alternative of common stringers supporting the stairs by slotting close to the edges, a central spine holds up treads on each of its sides. The actions are also bolted to steel suspension rods that offer additional support and function as a lightweight balustrade.
Frameless glass balustrades had been extra on the landing to allow as much daylight as attainable to permeate the area.
The best steps are created from sound metal to avert the within of the floor from becoming exposed.
