New blocks of flats are being built which provide more services than people enjoy in houses or older blocks of flats. There is not only electricity for lighting and power, but also for central heating. Some flats have central air-conditioning systems. The roofs are often flat, and part of the roof can be used for drying washing. There are staircases and lifts, storage rooms, and sometimes a laundry in the basement, and covered parking spaces for cars. When these flats are planned, care is taken to make sure that each flat gets plenty of light.
