SO&CO has slotted a skinny office building into an alley between two buildings in Tokyo, Japan, which contains five tiny concrete workspaces.
The office block, named the Multi-Tenant Building in Ginza, is located on a narrow L-shaped plot on a densely-packed backstreet in one of the city's leading shopping districts.
It has a stark concrete facade designed by SO&CO to stand out against the backdrop of the "solid and unattractive" buildings that typically occupy these side streets to grab the attention of passersby.
Like the facade, the interior finishes of each office is characterised by the exposed concrete structure.
