Up, basically the same process I'm going through but a 20x70 unit in Pusat Bandar Puchong. Parking for future reference.

Btw, I already found a contractor and someone to process MBSJ permit if you want me to share it. But for my house:
1. Extending only half of the house all the way back. The othet half is an open courtyard with awning and high fence.
2. Extend car porch with bigger gate and move pillar to park 2 cars
3. Break down multiple walls for more space. Enlarge 1st floor bathrooms
4. Redo wiring, plumbing, fix roof
5. Retile kitchen, 3 x bathrooms, and SPC flooring for 1st floor + staircase.
6. Fresh coat of paint both interior and exterior

Was quoted 205k excluding cost of windows, doors and automatic gate. Also excluded cost of 5.5k for plan drawing and processing MBSJ approval.
