Hi guys, I'm planning to renovate the family house for the future.

As of now, it's a single storey house, but I'm planning to rebuild it to double storey .There's a couple of house from the same row that've renovated to double storey and i think that shouldn't be too much of an issue i guess.

I've consulted freelance ID and will be needing more of architect/ contractor to quote and also explain details mostly revolving around

1. do we need piling work for such rebuilding? others neighbour have done such rebuilding but mostly did footing fortification only. my house is 1200sqft, around 18 x 65 land size. (already called MPAJ and they confirmed that we can do rebuilding of an additional storey up

2. what do you guys expect the cost gonna be, will 500k be enough without taking into consideration of the loose furniture / electrical stuff . it wont be any fancy-fancy  design or state of the art work but trying to keep it comfortable and all.

Any help is helpful for these, thanks in advance!
