In April 2005, the HDB announced plans to build a new mixed-use development at Clementi Town Centre, on the existing bus interchange site. The new development complex was to house a 5-storey retail podium with two basements, two 40-storey residential blocks (Clementi Towers), the West Coast Town Council (Clementi Office), a public library and an air-conditioned bus interchange. On 21 May 2011, The Clementi Mall – the new retail shopping mall which is part of the mixed-use development, officially opened. The mall is linked directly to Clementi MRT station on the 3rd level, and the new air-conditioned Clementi Bus Interchange at the 1st level has direct access to the mall. It is the first development in Singapore to integrate public housing, public transport and commercial facilities built together within a single complex. On 15 May 2012, the mixed development won the prestigious international FIABCI Prix d'Excellence award, scoring the Runner-up award under the Master Plan Category.
