Lengthy horizontal windows step around the matt black facade of this family home in Osaka by Alphaville Architects to frame different views of the close by Yodo River .
The Kyoto firm named the project Spiral Window Home soon after the succession of openings that are staggered across the walls.
The positioning of the windows is created to give views of the river, which flows from Lake Biwa by way of the city to the sea through Osaka Bay. The twisted arrangement also helps to stop the developing becoming ignored from the properties and roads that hem it into its narrow plot.
“The client’s demand was to reside even though appreciating the Yodo River flowing in the front of his eyes, and also to appreciate the annual firework competition of Yodo River from the rooftop terrace,” explained the architects.

“That is why we displayed spirally small openings from the ground to the third floor, as if they had been swirling.”
The property has a black-painted exterior, and a bright white interior.
The high place of one particular window blocks views into the master bedroom and entrance hall that occupy the ground floor of the block. The open-program living spot on the floor over functions 4 massive windows that frame views of the street, river and treetops.
“We realised in the centre of the city a living area that has a feeling of freedom, and privacy, not by putting in a big window in the centre of the elevation, but by displaying good deal of little windows,” mentioned the studio.
The children’s bedroom sits on the prime floor of the creating, which is set at an angle to accommodate a triangular terrace.
A wooden staircase winds clockwise up through the interior in the opposite route to the windows. It emerges by way of triangular cutaways in the corner of every single floor.
“Though it is a minimum operation of geometry, by the line of flow and the openings nestling concurrently, and reversing at times, a sophisticated relation with the exterior is developed,” added the studio.
Each of the walls is supported by a steel frame that follows the exact same spiralling succession as the windows, helping to bear the weight of the irregularly shaped construction.
Housing by Alphavilla usually functions unusual arrangements of windows openings.
In a recently finished house near Osaka, the company chose to place windows inside a deep slice in the building’s side to give views amongst the two sections of the residence. Similarly, a steel-clad residence by the studio in Kyoto hides its windows in two crevices.
