London Design Festival 2015: UK design studio Fredrikson Stallard has produced a collection of sculptural furniture – including a sofa that looks like a chunk of rock – to mark its 10th anniversary (+ slideshow).

Fredrikson Stallard's Momentum collection includes 10 new pieces that were displayed at the studio's headquarters in Holborn during the London Design Festival.

Patrik Fredrikson and Ian Stallard created their first collection for an exhibition titled Gloves for an Armless Venus in New York 10 years ago.

The designers have since created tables made from crumpled sheets of metal and a series of crystal lamps resembling the human eye.

In celebration of the anniversary, they have produced a new collection of objects "whose existence is derived purely from their core ideologies and vision".

"For us, Momentum is a celebration of the experimental and the rigorous, the unique versus the mass produced, the importance of conceptual and creative development underlining the artists' aesthetics and beliefs," said the duo.

"Momentum is also an anniversary of 10 incredible engaging years of working with visionary patrons and craftspeople who have helped facilitate the development of true creativity into extraordinary works, and this show acts as a personal interlude towards future destinations," said Fredrikson Stallard.

The works include a red sculpture called Species that looks like a chunk of Martian rock, but is designed as a sofa.

Other pieces incorporate the duo's signature creased metal in various ways. A pair of consoles have metallic fronts that appear to have be crushed, but with spaces filled in to make each of the other sides flat.

Sheets of metal are scrunched up to fit into a glass box to form the low Parachute table, while the Tokyo table has dents in one corner that warp and ripple the shape slightly.

Non-functional designs feature similarly crumpled metal balls with golden edges, which sit on top of plain rectangular plinths.

The exhibition was supported by London's David Gill Gallery, which represents the studio. Previous Fredrikson Stallard designs that have been shown in the gallery include the King Bonk armchair and footstool.

David Gill set up his Mayfair-based gallery in 1987, and has also exhibited furniture pieces by Zaha Hadid and Mattia Bonetti.

Currently on show is a range of glass storage units designed by David Chipperfield, which are supported by metal poles shaped to resemble Ionic columns.

The Momentum exhibition took place as part of this year's London Design Festival, which ran from 19 to 27 September 2015.
