There's an upside-down living room on the ceiling of this Polish fashion boutique created by design studio smallna for fashion brand Risk. Made in Warsaw (+ slideshow).

The designers at smallna were influenced by the reversible nature of Risk. Made in Warsaw's clothing range, in which items can be worn inside-out or back-to-front, to create the illusion of defying gravity.

An inflatable sofa by Polish brand Malafor, a chair and a side table have been fixed to the ceiling, along with a crumpled skirt and a pair of shoes that appear to have been discarded onto the simulated floor above.

White-painted steel pipes protrude from the walls, ceiling and floor, snaking around the perimeter of the space and forming rails from which clothes appear to hang in both directions.

A circular dressing room wrapped in a grey fabric curtain extends the full height of the shop, connecting floor to ceiling as though it could be accessed from either plane.

An upside-down balloon that appears to be made from concrete hangs from the ceiling, seemingly reversing the rules of gravity.

The same balloon, when viewed from the reversed perspective, appears to be floating but held to the ground by a brick. Smallna collaborated with Polish artist Joanna Gwóźdź to create this deceptive installation, whilst Daiusz Fiet - another Polish artist - painted the walls of the shop to look like the sky.

Vintage light fittings are dotted around the space, including 1940s American train lights, 1960s Polish tram lights and a Japanese mirrorball from the 1970s.

All the soft furnishings throughout the shop are made from the same grey melange fabric that the Risk. Made in Warsaw designers use to make their clothes.

Other shop interiors we've recently featured on Dezeen include the Who*s Who fashion boutique by Italian designer Fabio Novembre and a series of five outlets designed by Zaha Hadid for Milan-based fashion designer Neil Barrett. See all our stories about shop design.
