Capsule Hotels

Four places where sleeping is separated from everything that normally surrounds it. A capsule reaches its form by taking things out of the room and putting them elsewhere in the building. What is not in this section is a small hotel room with thin walls: the compartment has to be a compartment, and the thing it does without has to be deliberate.

Hotel Zen Tokyo

Tokyo, Japan

Compact sleeping modules in Tokyo built without a window to the outside world

Compact Tokyo sleeping module with a mattress at floor level and no window — Hotel Zen Tokyo, Tokyo

IWhat it does without

None of the sleeping modules has a window to the outside. There is no frame, no glass and no view of the street or the sky from the bed. The compartment is closed on every side except the one you enter by, and daylight never reaches the space where you lie down.

IIWhat stands there instead

Enclosure is the design, and the module is tuned for it: controlled light, a mattress at floor level, a shelf within reach, and ventilation carried through the structure itself. Shared washrooms and a common area sit outside the sleeping space, so the compartment only ever has to hold sleep and nothing more.

IIIWhere it shows

It shows on waking, when the hour is whatever the phone says and nothing in the compartment agrees or disagrees. It shows again when you step into the shared area and meet daylight for the first time.

See to thisSet an alarm you trust, because nothing in the module will tell you the light has changed.

Capsule & Sauna Rosco

Tokyo, Japan

A classic Tokyo capsule house where all washing happens in one large shared bath

Rows of classic capsule berths on a Tokyo sleeping floor with lockers along the corridor — Capsule & Sauna Rosco, Tokyo

IWhat it does without

Guests here have no bathroom of their own. The capsules are for sleeping only: no basin, no shower and no door that closes on a private washroom. All the plumbing of the building is gathered in one place instead of being repeated over and over on every sleeping floor.

IIWhat stands there instead

A large communal bath and sauna carry that function for the whole house. Washing is done seated at a row of taps before anyone enters the water, which is the ordinary Japanese order of things. Lockers, towels and a changing room stand between the sleeping floor and the bathing floor.

IIIWhere it shows

It shows the first evening, when getting clean means leaving the capsule with a towel and entering a room where strangers are doing the same thing in the same order, unhurried and without ceremony.

Len Kyoto Kawaramachi

Kyoto, Japan

Kyoto sleeping modules closed by a curtain, above a ground floor open to the street

Kyoto sleeping module closed by a fabric curtain along a dim shared corridor — Len Kyoto Kawaramachi, Kyoto

IWhat it does without

Each sleeping module here closes with a curtain rather than a door. There is no hinge, no latch and no solid panel between the bed and the corridor: cloth is all that separates them. Nothing in the compartment locks from the inside, and sound passes through it as sound does.

IIWhat stands there instead

A locker takes the job of the lock, and the building takes the job of the door. Bags go into a separate secured cabinet, the corridor is kept dim and quiet, and the ground floor is a café and bar open to Kawaramachi, which puts the noisy hours downstairs and away.

IIIWhere it shows

It shows when you draw the cloth across and the room does not click shut. Footsteps stay audible, light shifts along the floor, and privacy turns out to be an agreement rather than a fitting.

See to thisBring an eye mask and earplugs, and keep valuables in the locker rather than the module.

ZZZleepandGo

Rome Fiumicino Airport, Italy

Sealed sleeping cabins inside a Rome airport terminal with no outside to look at

Sealed sleeping cabin inside an airport terminal with an interior wall and no window — ZZZleepandGo, Rome Fiumicino Airport

IWhat it does without

Nothing in these cabins looks out. Placed inside the terminal itself, they have no exterior wall, so there is no window, no sky and no way to read the weather or the hour from where you lie. The view a hotel room usually supplies is not part of the plan.

IIWhat stands there instead

The terminal becomes the surroundings, and the cabin answers it with a bed, a lamp, a socket and enough soundproofing to hold the airport at a distance. The small units are sized for a short sleep between flights, with washrooms nearby, so the whole design points inward, at rest and nothing else.

IIIWhere it shows

It shows when you step back out and the light in the hall is exactly as it was, whatever the clock now says. Inside, the walls give no clue at all, and time comes only from the departure boards.

See to thisKeep your own alarm and your flight time to hand, since nothing in the cabin marks the hour.

An absence here is something a building was designed around, not something missing from it. We take these from published sources and describe them in our own words; the month at the end of an entry is when those sources were last checked.
