Shiro Studio is among three firms vying for an outdoor sculpture for children at Snape Maltings in Suffolk
The announcement comes two years after the outfit – set up by former Future Systems architect Andrea Morgante – won the RIBA contest for a £2 million Great Fen visitor centre in nearby Cambridgeshire (see AJ 16.05.13).
The shortlist is completed by sculptor Yonatan Vinitsky and Germano Di Chello Architects with artist David Rickard.
The three finalists will receive £1,000 each to develop designs for the new £50,000 vantage point overlooking the marsh landscape which already features works by Henry Moore, Barbara Hepworth, Sarah Lucas and Alison Wilding.
Backed by Aldeburgh Music and Suffolk Coastal District Council, the project is planned to complete in time for the 69th Aldeburgh Festival which will be held at the historic arts complex in June 2016.
Judges include Aldeburgh Music chief executive Roger Wright; artist Ryan Gander; and architects Sam Price and Patty Hopkins.
Constructed in the 1800s, the iconic complex was originally used for malting barley for the brewing industry but was shut down in the 1960s.
The buildings overlooking the River Alde were later converted into a concert venue for the Aldeburgh Music Festival and the complex now features several shops and restaurants.
Haworth Tompkins has completed several projects at the former maltings including a £450,000 café, a £6.5 million residential scheme and a £5.5 million creative campus.
The firm’s £155,000 Dovecote Studio rehearsal room at Snape won the 2010 AJ Small Project Award.
A winner – planned to be announced on 5 October – will receive a £15,000 prize and the commission.
