Ryuichi Sasaki Architecture uses trapezoid motifs for concrete housing in Tokyo
Trapezoidal motifs appear throughout this concrete condominium block in Tokyo, designed by Japanese studio Ryuichi Sasaki Architecture.
Named Shin Nakano Trapezoidal, the five-storey block of 11 residential units was designed for local developer Real Partners.
According to Ryuichi Sasaki Architecture, the angular, trapezoidal motifs that feature throughout the design were informed by the project's location on the Musashino Plateau, a large tableland in western Tokyo.
"The Musashino Plateau is one of those landscapes that people live on without ever seeing," said principal architect Ryuichi Sasaki told Dezeen.
"Our challenge was to take something as abstract as a position within a plateau and translate it into a motif that residents encounter every day," he continued.
"[It is] in the facade they walk past, in the shadows on the stairs, in the light that reaches their rooms."
On the block's eastern edge, a sheltered entrance area is framed by tall, trapezoidal concrete columns and features trapezoidal floor tiles.
A large sliding metal door leads into a lobby and stairwell, where an industrial-feeling steel staircase with grille treads allows daylight to filter through.
This lobby divides the block into three wings across which the apartments are separated, with a combination of single-storey and duplex units that extend into a basement and rooftop terrace.
Each apartment takes advantage of views over the street to the south and a park to the north, with large metal-framed windows that slide open for cross-ventilation.
The interiors are deliberately minimal and pared-back, with timber floors, exposed concrete ceilings, white-painted walls and large areas of built-in storage.
The trapezoidal motif was carried through into openings in the interior walls and floors, staircase balustrades and even the floor plan of some rooms.
Externally, the block is finished in exposed concrete, with textured trapezoidal and triangular panels created by embossing the surface of the concrete after it was poured.
"A residential building of this scale is experienced in fragments — an entrance, a stair, a window — so the motif had to work at every one of those moments," said Sasaki.
"We are proud to offer the residents of Nakano a building that connects them, quietly and daily, to the ground it stands on," he added.
Previous projects by Ryuichi Sasaki Architecture include a mixed-use development containing homes and a community performance space in Tokyo, which was housed within similarly angular concrete volumes.
Elsewhere in Tokyo, Kenta Hirayama recently created the steel-clad House in Kinuta and Kenta Sano & Associates combined a glass-fronted dance studio with a house.
