A model of architect Will Alsop's vision for Barnsley, in Yorkshire, will be on display at the Royal Academy Summer Exhibition, which opens on Monday, 2 June. Measuring 3 × 4 m, the model is designed to provoke discussion about development policy over the next 30 years. The display is part of a strong architectural presence at the gallery, which will also includes an exhibition dedicated to tall buildings. The exhibition, called Sky High: Vertical Architecture, will include 50 projects by architects such as Richard Rogers, SOM, Massimiliano Fuksas and Renzo Piano.
