Based on my own home previous reno, RM200k doesn't accomplish as much, certainly not with the amount of work being done to this house. With the extent of work shes done from roofing, change of facade, etc... it looks like thats the cost for the masonry and structural work.
And I don't provide any renovation service or work, but I did manage my own house renovation in the past. Estimation purely based on own experience and taking into consideration that material and manpower costs have gone up since I last did my own place.
Simple breakdown:
estimated cost for 3 phase wiring, lighting & fixtures: RM30k
estimated cost for plumbing work: RM15k
estimated cost for built-ins for kitchen & wardrobe: RM25k (for those 3G type)
estimated cost of painting the entire house: RM15k (inclusive of paints)
Flooring cost (ground): tile, marble? cost would differ greatly dependent on material used
Flooring cost (1st Floor): tile, laminate, engineered, solid timber? again cost would differ.
Cost of doors, door frames, fittings?
Bathroom tiling, fittings?
Staircase railing, finishing for the steps?
Gate & electric motor?
Porch tiling?
Plaster ceiling work?
Kitchen appliances?
Air conditioning?
Everything adds up, and just doing a simple breakdown will show that the whole project will definitely pass the RM200k mark, especially when looking at those 3D renderings.

yes u r rite lol... the exact figure i dont find like putting here. as i feel insecure.
