The sleeping unit, not the room, is the unit of plan here
Capsule Hotels · 4
Four places where sleeping is reduced to a single closed unit, either inside an airport or on a city plot with no room to spare. They belong here because the sleeping module is the whole plan rather than one room among many. Hostels with ordinary bedrooms, and hotels that simply have small rooms, are not part of this section.
TERMINAL
07
Napcabs
Munich Airport, Germany
In a sentence Sleeping cabins placed inside the airport itself, on the far side of the security check
The condition
The setting is a departure area at Munich Airport, not a street. There is no plot, no facade and no quiet hour: the floor is lit and used around the clock, announcements carry, and every square metre is already assigned to circulation, gates or retail. Anything placed there has to be small and self-contained.
The answer
The answer is a freestanding cabin rather than a building. Each unit is a closed box with a bed, a desk, a light and its own ventilation, set directly on the terminal floor within reach of the gates. The walls are solid on all four sides to cut the noise and light of the hall, and the cabins are entered at the door itself.
A cabin standing on the open terminal floor
What you see of it
From outside they look like a row of plain boxes standing in the hall, with people walking past on both sides. Inside, the terminal drops away to a low hum, and the whole room is the length of the bed.
One more thingThe cabins stand airside, so check that your ticket and transit route let you reach that part of the terminal.

Air Rooms Madrid Airport
Madrid, Spain
In a sentence Compact rooms held next to the terminal, arranged around the walk between one flight and the next
The condition
Madrid-Barajas spreads over a large area, and its terminals are linked by transfer routes rather than by streets. A traveller between flights has luggage, a boarding pass and a limited walk. There is no neighbourhood around the site, and the surroundings are roadways, car parks and terminal buildings.
The answer
The rooms are kept small and placed as close to the terminal as the site allows, so the distance from the concourse stays short. Each unit holds a bed, a shower and a work surface and nothing else, and the walls are built to keep out the sound of the airport. Access is direct from the terminal level rather than through a car park.
The covered walk between terminal and rooms
What you see of it
The walk is short and stays under cover, with signs rather than a street address to guide you. The room is plain and tight, and the only view is the airport, which is what the place is for.
One more thingConfirm which terminal you need before you set out, since the transfer between terminals is a journey in itself.

Grids Tokyo Ueno
Tokyo, Japan
In a sentence Sleeping modules stacked in tiers on a narrow city plot a few streets from Ueno
The condition
Ueno is built close, and plots there are narrow and deep with buildings on both flanks. A site of this shape gives very little frontage and almost no daylight along its long sides. Stairs, services and circulation take a large share of the floor before any sleeping space is counted.
The answer
Sleeping is separated from everything else. Modules are stacked in tiers along the depth of the plot, each one closed with a screen, so the narrow floor carries far more beds than rooms would. Washing, luggage and sitting are moved to shared floors, which frees the tiers to be nothing but berths. Light is brought in at the ends where the plot meets the street.
Sleeping modules stacked along the depth of the plot
What you see of it
The front door is narrow and easy to walk past. Inside, you move along a corridor of openings rather than doors, and your own space begins at the edge of the mattress. The building gives you a bed, not a room.
One more thingSleeping berths are closed with a screen rather than a locked door, so plan where your valuables will go.

UNPLAN Kagurazaka
Tokyo, Japan
In a sentence Curtained sleeping modules in a shared hall on a dense residential slope in central Tokyo
The condition
Kagurazaka is a hillside of small streets, low houses and shops set tight against one another. Plots are modest, and neighbours stand close on either side. A building here cannot spread outwards, and much of what it looks onto is the wall or window of somebody's home rather than open ground.
The answer
Instead of dividing the floor into small rooms, the plan keeps one large hall and fills it with sleeping modules closed by curtains. The walls that would have separated rooms are removed, so the same floor holds more beds and still has room for a wide ground-floor space that opens to the street and serves as cafe and common room.
Curtained modules in the shared upper hall
What you see of it
The ground floor reads as a cafe with people coming in from the street. Upstairs, the hall is quiet and dim, and the difference between your space and the next one is a curtain.
One more thingSleeping space is divided by curtains in a shared hall, so bring an eye mask and earplugs if you sleep lightly.

A condition is our shorthand for the circumstances a building had to work with, taken from published sources and written in our own words. It is not a category anyone applied for, not a difficulty score, and not a promise about a stay. The month under an entry is when we last checked those sources.
