In this new update I added the following:
Helicopter landing area
Suiciding area
2nd pool + jacuzzi
Small disco room
New house
2 awkward looking structures
Double the size of the terrain

In the next update I will add:
Triple the size of the terrain
Very large disco room
3rd pool (I forgot to add this)
Scenery area
Underwater area of house (I also forgot to add this)
Battle Arena
2 New parts of house

I am already starting my new update

P.S. the arena will not be part of the terrain (the arena is supposed to be modernized)
