"The aim was to fit as much product in to the space as possible without it becoming overly cluttered," Lamb told Dezeen. "I wanted to give an illusion that it was much bigger than it actually is."
He covered three sides of the room with a floor-to-ceiling latex curtain to "invite the question that there might be something behind it".
The curtain serves to hide the concrete walls and service wires, as well as incorporate a fitting room and storage space. "Latex rubber was chosen because of the way that it hangs," said Lamb. "It has this soft, absorbing, lustrous feel."
The material is formed into vertical ripples that continue to the floor, aiming to draw attention to the height of the space rather than the small footprint.
A continuous clothes rail suspended from the ceiling is made from the same custom-bent steel tubes used as handrails on London Underground trains and painted the same bright blue as used on the Victoria Line.
"It wasn't a conscious decision to make it that colour," said Lamb, "but at the same time it was a reference that I couldn't ignore, using the same materials and producer as the Underground rails."
Circling the store, the rail meanders up at various points to make way for the entrance door and allow access to the changing room. "It serves as a window display for clothing, eliminating the need for mannequins because the space isn't big enough for them," Lamb said.
The rail is suspended from the ceiling to provide additional display space around the edge of the floor. To lift shoes and bags off the ground, Lamb created plinths from polystyrene offcuts that he sprayed with peach-coloured rubber.
More display space for smaller products is provided by a steel ladder, with shelves that can slide up and down two tubes and be locked into place with pegs. A slab of red Welsh sandstone, sanded by hand on the top, forms a low stone table in the centre of the space.
The service counter is made from a stack of sheets of glass that Lamb stuck together himself with silicone sealant, which he also rubbed over the inside surfaces with his fingers.
"The same silicone served as the masking material to whiteout the glass, like the whitewash you'd see on the facades of shops when they're being renovated," said Lamb.
The London-based designer had seven weeks to complete the design, which has an indefinite life span as the pop-up currently has no closing date. He chose durable materials that could last as long as need, but elements can also be easily removed and reused.
Along with Opening Ceremony's menswear and womenswear collections, the store will host garments by a range of emerging designers and well-known brands.
