From mattresses on concrete bases to beds encased within timber surrounds, this lookbook rounds up ten single, double and day beds that have been built into interiors.

Some designers choose to integrate beds into the building's wider structure to create cohesion throughout interiors, eliminating the need to add matching furniture.

Built-in beds are often seen in buildings situated in warmer climates, such as Central America and the Mediterranean, where stone or concrete is used to keep spaces cool and to create bespoke, unmovable furniture.

Incorporated beds are also a popular choice when designing wooden cabins, due to their space-saving nature and the way they lend themselves to creating a cosy atmosphere.

This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks featuring lime plaster walls, red interior schemes and interiors informed by retro design.
