Spatial separation can be as much about a feeling of enclosure as a physical divider, like this set of portable lounge structures that provide a semi-secluded experience in an otherwise wide-open space.

Proposed by Malcrew for a co-working office space in an old Singapore warehouse, these mobile mini-rooms offer seating and shelving that can be deployed in a variety of personalized configurations.

Better still, like slices of a house set side by side, the disparate units can be slid back together to form gathering or meeting spaces on demand.

Individual cushions can also be removed from each structure to make legroom for sitting upright and, in turn, be used as stools as well.

Inspired by treehouses, white oak frames reference wooden home construction, while brightly-colored interior cushions and walls distinguish the different modules from one another.
