In a house for four located in the suburbs of Hiroshima, Japan, a central staircase stands like a thick tree trunk at the heart of the residence. Three bedrooms clad with coniferous plywood are suspended from this core, each at a different height and turned at different angles.
Architect Francesco Librizzi built this staircase for the Casa G project as a means to slow the ascent, to create stations that infused the interior with life. Recalling the rectilinear compositions of Piet Mondrian, the oak-and-steel structure is as much a sculpture as it is a means of going between floors.
Resident Martha Moseley notes the staircase as one of her favorite features of her Pennsylvania home, made of eleven shipping containers. “When the steel was ordered from the steelyard,” she says, “it was marked with our metalworker’s name, for easy pickup. That scribble still exists in random places in the staircase and is very industrial—we love it!” Hand-welded by Mike Carman, a local contractor, the staircase runs through all three floors, and it was custom-sized to fit the dimensions of the shipping containers, measuring nine-feet-six-inches tall and eight-feet wide.
At this London renovation by Scenario Architecture, the central staircase is a key element of the scheme. With the bedrooms and bathroom located on the entrance level, it was crucial to create an intuitive and inviting flow up toward the more social areas. On the upper floor, the central staircase divides and defines an otherwise open plan.
Anchored in a small canal, this floating house on the San Francisco waterfront was fabricated by Stocklin Iron Works and designed by Nebolon. Inside, the orange staircase features steel railings and treads were made from IKEA wood butcher blocks. “We designed the open staircase to make the trip to the second floor fun,” the architect says.
Beneath the facade of this Victorian townhouse renovation in London hides a sophisticated modernist plan and a towering library structure with 330 linear feet of books. Reaching for the skylight, the five-story staircase is met at the top by the custom bookcase.
The rural getaway that architect Robert Konieczny designed for Jacek Perkowski in southwest Poland features a grass-covered roof and staircase, which add up to save 25 percent a year on climate-energy costs.
Leading from ground-floor up, this custom, metal spiral staircase leads to the ultimate rooftop hangout at this Northern California residence. It was built as part of a new addition, which according to architect John Klopf, acts as a spatial backdrop for the existing structure, “receding visually out of respect for the original home.”
