DEMOLISHING to rebuild is an idea whose time has come. It is an idea that has been tried and tested as well, albeit in Singapore. Finally, the bottom 40 per cent (B40) income group can see their wish for a quality, affordable home fulfilled under the People’s Housing Project (PPR). A 2011 study conducted by Goh Ai Tee and Ahmad Yahaya of the Department of Architecture, Faculty of the Built Environment, Universiti Malaya indicated that there were 63,377 of such units in the country, of which 34,106 were in Kuala Lumpur. Many of the PPRs were built in 1998 to implement the country’s no-squatter policy and they bear the marks of ailing apartments in need of urgent repair. Complaints from apartment dwellers are aplenty. Water dripping through walls and ceilings, clogged manholes, malfunctioning lifts are some common laments.
