Wah TS ur house so nice, can I ask u some questions as I recently bought a double storey 24x64 built up only 1650sqf. Everything not usable, wiring and piping all those also need to do, basically need to reno from scratch. 4 bedroom 3 bath. Can I know in your experience, roughly how much to reno all? Let say exclude extension but do u know like ask architect to draw and get approval for extension cost how much?
