A divided monolith of exposed concrete

Residential and Commercial Building in Tokyo by Sasaki and Ytro

 - Jakob Schoof

The Escenario Shirokane residential and commercial building by Sasaki Architecture and Ytro Design Institute asserts an unconventional presence by Tokyo standards, both because of its location and thanks to its expressive exposed-concrete architecture.

The six-storey new building occupies a corner lot in the central, wealthy district of Shirokane. The structure that previously stood here housed the offices of a newspaper-delivery company. The roads in the area are somewhat broader than usual in Tokyo − which explains why every building erected here is visible from a distance.

For the exposed location, Sasaki Architecture and Ytro Design Institute designed an enormous sculpture whose exposed-concrete façades seem to transition seamlessly into the grey-coated roof surfaces.

Smaller areas, rather like gills, fold out of the façade − a purely formal means to visually direct our gaze around the corner building. The ground floor is home to a restaurant; each of the three levels above it is home to one single-room apartment and one two-room flat.

In the larger apartments, the bedroom can be delimited from the living space with sliding walls. All units have been offered for rent. The very top of the building features a two-storey maisonette-style office that is currently used by Sasaki Architecture themselves. In principle this unit, with ceilings as high as 3,7 m, could also be repurposed as a flat.

Various wall surfaces demonstrate the functions of the walls in this building. The exterior walls are insulated on the interior side and clad with plasterboard; however, on the walls of the access core and those that separate the apartments, the concrete surfaces remain visible.

  • The new seven-storey building on Hohlstrasse in Zurich will comprise a ground floor with retail space and public service areas, and five upper floors with commercial space.

    Railway Tracks as a Supporting Structure - How Does That Work? 

    Around 180 kilometres of track are replaced every year on the Swiss rail network. Until now, all this scrap metal has been melted down. However, the first building with a steel framework made from recycled rails will soon be constructed in western Zurich.

  • Landscape architect Line Ramstad is the new chief curator of the Oslo Triennale.

    „One Size Does Not Fit All" 

    Facades made from waste wool, recycled steel from decommissioned ships, housing rather than investment property: Line Ramstad, chief curator of the Oslo Triennale, shows what happens when nature takes precedence.

  • Paul Van Ostaijen Culture Campus in Leuven

    Lava architecten transformed an old mission building in Leuven into a place where circus arts, music, theatre, and dance coexist under one shared roof. Effective soundproofing is the precondition for the shared use of the facility.

  • Even though the main exhibition pavilion in the Giardini was closed, the 2025 Architecture Biennale featured more exhibits than ever before.

    Self-Exploitation in the Celebrity Circus

    At every Architecture Biennale, the curators face the same obstacles: a lack of funding, a great deal of red tape, and an organisation that ignores collective achievements. Why do they put themselves through this? We speak to Albena Yaneva, who spent a year observing the development process of the 2025 Biennale.

  • A vision for the future of Barcelona: Boltshauser Architekten have designed demountable street furniture made from concrete blocks for the Catalan metropolis. The blocks are made from recycled lean-mix concrete layers under roads.

    An End to Downcycling  

    In its current form, concrete recycling does little to help climate protection. The CO₂-intensive cement is lost irretrievably in the process. Boltshauser Architekten are working with a consortium from the Netherlands, Switzerland and Spain on the Respira research project to investigate how this can be avoided.

  • Stress tests have shown that re-use prestressed concrete slabs deflect significantly less than conventional reinforced concrete slabs.

    Slabs Under Tension 

    Concrete floor slabs have the largest carbon footprint of all building elements. In the past, the material was lost irretrievably during demolition. A Swiss consortium is now cutting standard square slabs from buildings due for demolition and using them to manufacture prestressed segmental concrete elements with a higher structural performance than new reinforced concrete.
