[u]Using 3 Voids[/u]
I plotted 3 spots of void to give a high space feeling at the front, middle, and back.
The aim of using this void it to make natural light from tall window at the front and back to be easier to infiltrate to inside of the house.
On the opened roof perspective I use different color of the tile on Ground Floor and 1st Floor to help seeing the voids.
To be noted, the front Void is covered with a massive wall on the 1st Floor, thus it keeps a privacy of 1st Floor. No one can see inside the 1st Floor from the front road. But still the natural light can be easy to infiltrate to the main area of 1st floor by passing glass block attached in the massive wall I mentioned.
[u]Prayer Room Position
Prayer Room separated from Laundry and Game Room, thus when someone will do praying in the room, he/she will not be disturbed of any activity in the Game Room/Laundry Room.
