Artist Isamaya Ffrench has opened her second-ever Studio Iron show as part of this year's London Design Festival, with participants including Andu Masebo and Barnaby Lewis.

Studio Iron is the brainchild of Ffrench, a makeup artist and creative director, who launched her collectible design gallery at Saatchi Yates earlier this year.

The project is back for London Design Festival (LDF), on display as part of curator Alex Tieghi-Walker's Perfectly Imperfect programme in the Brompton Design District.

Ffrench selected 27 creatives for the exhibition, featuring pieces that challenge ideas about what materials go together.

"Our designers are based all over the world, and as someone who's highly into the tactility of objects and art, it was amazing to see all the pieces in real life," she told Dezeen. "To see how they looked, what they felt like, and to witness their scale."

"Most of the time, we get to experience art and design on the internet, in museums or in shops as the finished piece with great lighting and great props," she continued.

"But I'm more interested in the process, the tools, the raw materials, and the industrial machines. It's a real privilege to be in an artist's space and to talk to them about their inspiration or see them at work."

Among the selection is a low-slung hammered steel pouf by Jesse Butterfield, topped with a lacy linen cushion by Jane Wright.

Opposite the pouf, an oversized, angular armchair by tattoo artist Thomas Cardiff is on display, crafted from a steel frame with a cowhide-clad seat and tattooed leather sides.

Marten Herma Anderson is showing a bloated resin lamp with a gridded pattern and a nickel-plated brass base, while Atelier Fomenta is presenting a bulb encased in a cylindrical slab of rubber held together with rivets.

A tangled stainless steel coat rack by Andu Masebo was placed in the corner of the gallery, close to a chunky hammered steel mirror, also by Butterfield.

Blacksmith Barnaby Lewis's spindly, skeletal chair features in the show, alongside a stainless steel floor lamp by Wretched Flowers, cloaked in chainmail, gemstones and glass beads.

Lewis is among the London-based rising talents spotlighted in the Dezeen Dispatch newspaper we published for LDF.

"Barnaby's practice is visceral and poetic at the same time and he's also wildly prolific," Ffrench told Dezeen. "His work deserves more attention."

London-based Ffrench said that she hopes to expand Studio Iron, which is still in its infancy, into an interdisciplinary creative agency that champions young designers.

"London feels genuinely open in terms of how people work," said the artist. "There's less pressure to attach yourself to a single practice, which makes it easier to move between disciplines."

"Galleries and shops are also much more inclined to represent and sell the work of emerging artists versus established ones," added Ffrench. "And I think it is vital to support them and help them grow."

LDF is in full swing in the UK capital, with current shows ranging from a lighting installation by Lee Broom to the launch of prototype furniture and object platform Lobby.

The Studio Iron show is on show from 12 to 20 September as part of London Design Festival. See Dezeen Events Guide for more architecture and design events around the world.
