What's the difference?

There are a few terms that you must get familar with when you are constructing your own house.

1) A&A : Alterations and Addition : This is one of the most common ones that you see. What it means is it basically just alter part of the structure and add more floor space. But there is a condition, the GFA( Gross Floor Area) increase must not be more than 50%

2) Re-Construction : As the term implies, it is to reconstruct the building from ground up, leaving skeleton core structure intact. Any GFA increase of more than 50% will be considered as reconstruction.

3) New Erection : This means 100% full reconstruction ( everything off ). With new erection, you can increase your ceiling height to up to 5m but there is a condition. You need to build a bomb shelter.
