This house has a pricey entertainment system that effectively turns it into four-storey jukebox.
The $100,000 system, which is at the top storey of Mr Ricky Lim's house near Serangoon Gardens, has a central network that streams music through a speaker on every level.
Family members can select songs and adjust the volume from anywhere in the house via their iPads. "The boys have similar tastes - they listen to Maroon 5 a lot," said Mr Lim of his two sons, who are aged 11 and 13.
The set-up also doubles as a massive entertainment system.
Mr Lim, 47, the managing director of BCS Information Systems, said it started with a quest to find the perfect sound as he loves music.
As he guided this reporter around his home theatre system with its huge 60-inch LCD TV, it became clear just how much effort went into the set-up.
This was no off-the-shelf purchase nor were the choices left to an expert.
Mr Lim wanted the best and he went around Singapore for about four months to find the ideal speakers.
He said: "My wife wasn't terribly excited because I was bringing her to different places just to listen to their sound systems."
