The Royal Institute of British Architects (RIBA) will announce the winners of the 2012 RIBA Awards on Thursday 21 June 2012. RIBA Awards for architectural excellence will be presented to 50 buildings in the UK and nine buildings elsewhere in the EU. The shortlist for the RIBA Stirling Prize for the building of the year will be drawn from the 59 RIBA Award winners. Italian architect Maria Giuseppina Grasso Cannizzo has won a RIBA Award for Architectural Excellence, for her design for a house in Sicily. The FCN 2009 house, situated on the side of a hill, in a seismic area, this is a lesson in freshness of thinking, invention and in the inseparable nature of structure and architecture. An apparently solid plywood-clad box floats above the site, pitched so as to enjoy the horizon and the distant sea. It prises open by means of a movable guest-wing, mechanically operated, which slides away to reveal a terrace and a glass wall to the main house. The main fixed element of the house is constructed in prefabricated concrete. The shortlist for the 2012 RIBA Awards: www.architecture.com - FCN2009
