British designer Lee Broom has transformed his east London showroom into a dark and moody living room, which is seemingly reflected in a giant mirror.

Broom designed the On Reflection installation for this year's London Design Festival, which coincides with his studio's 10th anniversary.

The installation seemingly presents a single living room reflected by a mirror. But it is actually an optical illusion – and the mirror is a large window to opening onto an opposing room that has been decked out to match.

The installation showcases all-black versions of Broom's best-known furniture and lighting pieces in a moody living room, comprising charcoal walls, dark carpeting and a roaring fire.

To create the reflection, Broom matched the location of each of the pieces. Wall texts and monochrome artworks depicting squares and circles were flipped horizontally to look as though they had been mirrored.

Among the pieces on show is the large, circular Carousel pendant and the Hanging Hoop chair, which is a swinging seat made up of interlocking brass-plated metal circles.

A set of On The Rock glassware is displayed on a series of podiums painted to match the colour of the walls. They are lit from above by a pair of Crescent lights – an illuminated sphere that appears to be cut in half and offset.

The totemic-style Fulcrum light is set on the fireplace, while a trio of Fulcrum pendants are grouped to hang together. The Altar Chair is placed along the back wall.

Broom, who started his eponymous studio in 2007, also celebrated his decade-long career at Milan design week earlier this year, where he presented a decade of work on a modernist merry-go-round.

"It has been a very special year, beginning with our celebrations at Milan Design Week, NYCxDesign and now in London," said Broom.

"The London Design Festival is always such a special show for me, and this year it is even more so, as it is our 10th festival and as we continue to reflect on designs from the past decade."

On Reflection is installed at Broom's showroom on 93 Rivington St, London, EC2A 3AY. It will be open for the duration of this year's London Design Festival, which runs until 24 September 2017.

Other installations on show during the event include a Camille Walala-designed inflatable castle in Broadgate and a micro home with attached library created by Sam Jacob and MINI.
