When Dr Michael Teo's modern terrace house was built last year, it caused a ruckus, with neighbours complaining that it did not blend in with all the other houses in the private estate near Toh Tuck Road.

His three-storey flat-roofed corner terrace house in Greenridge Crescent stands out among the more than 70 Tudor-style homes - with a timber and pitched-roof design - that were built in the 1980s.
