Spanish architecture firm Elii has managed to pack a tiny, 620 square foot attic loft in Madrid with a bevy of space-saving contraptions.

Making the most of a constrained floor plan required a ruthless approach to space maximization, as well as a dose of quirky creativity.

Smart shelves that swing down from the ceiling, creating unobtrusive spots to store rarely used items, are a genius idea that should be productized and sold as construction modules.

A clandestine dressing table was a hard requirement from the client, but every pocket of empty space was evaluated as an opportunity to add a charming capability.

Extra counter space can be pulled out of a pocket in the kitchen wall.

By cranking a handle on the wall, a bungee cord actuated pulley drops ceiling tiles that become a picnic table/bench in the kitchen.

A hidden hammock seems like a twee touch in a manic pixie dream house.

"Every house, in a way is a theater, where you perform your everyday life," says Elii partner Uriel Fogué Herreros.

Skylights and transparent panels in the partitions allow natural light to filter through the entire house regardless of how it's configured.

Hardwood flooring and ceiling panels were replaced with oriented strand board plywood. "We have used OSB in other works and we loved the result. It is warm and, at the same time, industrial," says Elii partner Eva Gil Lopesino.

"She describes herself as a heavy metal fan that is very fond of Hello Kitty," says Elii partner Carlos Palacios. "We tried to respect her taste and translate it into the aesthetic of the place."

The apartment was renovated from the walls in, swing included, and a complex mansard roof was repaired, all for a budget of just $75,000.
