Cost to A&A / Reconstruct Semi-D Exterior & Additional 1.5 Floor

[postcard 0]

Hi, I'm new here. I just bought a 2 storey, Old Semi-D. I need to build up to 3.5 storey with roof terrace etc.

I'm here to find out more about the cost of A&A/ Reconstruct the Semi-D Exterior & Additional 1.5 Floor.

Should I get an Architect to do everything or to get a Builder to do everything. If i missed out other info that I need to write here, please kindly do highlight to me too.  Thank you! =)

U shd start with an architect to discuss with u hw to turn yr ideas into a buildable plan that complies with sg regulations. Work with the architrct to get to the URA "written Permission" stage. Then go find a "design and build" contractor.
