Eye of the Collector will be held at Two Temple Place – a building on Embankment behind The Strand in London – in May 2020.
The late Victorian neo-Gothic mansion was commissioned in 1892 by financier and statesman William Waldorf Astor.
Vassegh said: “Our exhibition is designed to showcase works of art as they might be presented in a collector’s home. Two Temple Place, referred to as ‘a perfect gem’ by Nikolaus Pevsner and with its extraordinary history of artistic patronage, really is the embodiment of this joy of collecting.”
The artworks exhibited at the fair will be from between 30-40 galleries, selected by a curatorial committee, featuring works from established and lesser-known artists.
Vassegh, previously a specialist at Sotheby’s, said her event will be for “collectors, curators, art professionals, interior designers, architects and art insiders”.
Entry will be by invitation only between May 13-14 and it is open to the public on May 15-16.
The building is now run by charity The Bulldog Trust.
