The Balcony incentive scheme was first introduced in 2001. Developers are encouraged to build more private outdoor spaces for private non-landed homes. Private outdoor spaces have an additional 10%GFA for developers under this scheme. URA wanted to improve the living conditions for homeowners, and at the same time provide them with an additional greenery space.

The balcony space was added too large to the inside space. Developers abused the system. People had no choice but to pay for these incredibly large balconies because they were included in the GFA. Knowing that buyers use bots to get the best prices, URA revised the BIS guidelines to prevent developers from exploiting buyers, while giving buyers more choices.

Bay windows

A bay window has an extended part that protrudes out. The bay windows in this home give it an outdoor feel. Bay windows are exempt from calculation. All but a small number of properties had this. Bay windows provided practical benefits, such as allowing natural light into rooms, that weren’t considered part of the original GTA.

This was a big issue for developers who wanted to build more bay windows and charge buyers for it. They were able to increase their profits and also reduce the average psf cost.

Some houses have bay windows all around. bay windows have been used to add a more inviting look and feel to the interior of the home bays were not included in new residential developments.
