Studio BAAD has unveiled its collaboration with a giant of US architecture, Philip Johnson. The 94 year old is working on the concept design with Studio BAAD for a £200 million retail and park development at Chavasse Park, Liverpool Docks. The scheme features a 300m long sculptural canopy made of glass and metal 'scales' which cover a retail development based around a series of walkways at different levels. A rooftop park will be built on top of the retail scheme. The scheme is due to be submitted for planning permission at the end of this month (see Astragal on page 66).
