HAD the Phua family painted their home a pale shade of yellow, it would resemble a block of Emmental cheese. Instead, they decided to stick to a safer colour - white.
Still, the home has been nicknamed The Hole House by its architects from Farm.
The semi-detached house, off Holland Road, certainly lives up to its nickname.
From the outside, it looks like someone randomly punched out squarish holes in the front and side walls of the houses.
Once you're inside, you can see that the holes serve a purpose as windows and skylights that let natural light into the master bathroom, and along a stairway leading to the study on the top floor.
"We wanted the house to have a light and airy feel with plenty of sunlight streaming in," says Max Phua, executive director at World Scientific Publishing.
The house appears to glow at night, with light coming out from the inside.
The Phuas were previously living in a two-bedroom apartment, but moved into this bigger place to accommodate a growing family.
To cope with the need for extra space, the architects expanded the home sideways and upwards, by building an additional floor, turning it into a two-and-half storey home.
