London Design Festival 2014: British designer Sebastian Wrong has added a number of fresh pieces to his collaboration with Danish design brand Hay, adding to the collection that debuted in London last year (+ slideshow).

A selection of products by Danish brand Hay and Wrong for Hay have been curated by interior stylists Benjamin Kempton and Melina Keays in a Georgian townhouse in south-west London.

Glassware, lighting, stationary, textiles and furniture by the brands are interspersed with planting and antique pieces in the showroom. "It's quite eclectic," said Wrong.

"I think it's very nice to allow other people to use your products to cook other foods sometimes," Wrong told Dezeen.

The showroom will double as a dining space during the London Design Festival – a daytime café and an evening restaurant will serve a fusion menu of Nordic and London dishes by Helsinki-based chef Antto Melasniemi.

A linoleum-topped trestle table and beach stool by London designer Simon Jones are among the new items unveiled by Wrong for Hay.

The two flat-packed designs are accompanied by a set of construction drawings on the showroom wall that indicates their assembly. This is the first range of products for commercial sale by Jones, who usually creates bespoke pieces.

Nordic designer Lars Fjetland has reinterpreted the classic desk lamp with a slanted stem that suggests the lamp might overbalance. The Cloche has a hollow die-cast aluminium stem allowing cabling to be concealed, while the cast iron base prevents the lamp from toppling. The light is available in a range of finishes including polished copper.

Three new pieces by Sebastian Wrong – a glass bottle, a floor lamp and a range of sofas – have also been added to the line. The Hackney sofa has a series of brackets that allows the sofa to be broken into sections for easy transportation up and down narrow halls and stairways.

Memphis group designer Nathalie Du Pasquier has produced a series of patterned textile designs for a set of towels called He She It Towels, as well as six new designs for printed and embroidered cushions. Curators Kempton and Keays have used fabrics from Du Pasquier's cushions to line the walls of the pop-up dining room.

An earthenware vase by Richard Woods has branches for spouts. The Tree Trunk Vase, available in three heights, is made from a peach stained clay and has a hand-painted wood grain design which creates a contrast between glazed and earthenware surfaces.

Two new sizes of The Pion Light by Bertjan Pot have also been released. The light features a composite paper shade that diffused the light to create a gentle glow. "It's a very pure, clean form," said Wrong.

The exhibition and café is open from 13 to 20 September at 34 Queen Anne's Gate, London SW1H 9AB.
