Quite pricey wo. I reno my corner lot inside out also didnt cost so much but back in 2010. 30% higher also is only going to be close to 200k.
I even used granite for my dining and kitchen cabinet, 8ftx2ft table top and one single piece of 4ftx9ft for dining.
I budget:
Furniture: RM20k
Living: RM20k
Kitchen: RM20k
Garden: RM5k
Others: RM25k
Total: RM100k should be able to kao tim when you know where to source the materials.
One example, you can go to Guocera in PJ, tell them you want to renovate kitchen, and need tiles, they will ask for dimension and draw plan with your shortlisted tiles.
They only charge rm200 for the plan if you dont buy tiles from them. I take the tiles spec and design to Jalan Ipoh which can offer same Guocera tiles 40% cheaper (Grade 1) and they calculate how much tiles i need + some allowance. Give the design to my own contractor - gao tim one section of the house.
My contractor can do tiling, plaster ceiling and reconstruction (piling, extension, modification) so, 1 contractor fee gao tim whole house, surely cheaper than 1 contractor for 1 section.
Similarly, my furniture guy can do ID and cabinet for entire house, so, save alot of cost on ID fees.
By reno time, we discuss lagi lo ... now too early de
