A house of that size will take more than 1 mil to complete. If your sister is an architect, she should know.

Unique bungalow will take cost about rm200-300/sqft. Your house looks like 5000sqft++. And that is structure cost only.

Interior furnishing expect to spend rm50-100/sqft more. Kitchen, wardrobe, sofa, bed etc...

Good luck trying to keep your budget down. Many ppl here can tell you where you can save a bit but my advise is - you are building a bungalow. Furnish it like one.

6300sqft trying to do under rm1 mil... Good luck.

Anyway your electrical is severely under design. In the living room, for example, you need plugs for tv, Astro, DVD, amp, sub, etc and these are only at the tv area (I would recommend at least 5x13A points there) that about the rest of the living? Stand lamps, mosquito coil , all sorts of charger, vacuum cleaner, etc. Better to have over design the electrical than to overload it later. You already spent so much on the house and this is not the place to save. Save it on cheaper finishes. Thing that can easily be upgraded later. Electrical is very messy to upgrade later.

Again remember that you are building a bungalow. Furnish it as one. Don't use instant hot water. Use the tank type. Think some forumers confuse it with centralize water heater. Tank type is the one where there is a tank boiler in the ceiling of every bath. I recommend to use individual tanks for each bath unless they are adjacent to each other. They cost similar to a normal instant water heater but you need to add extra plumbing and mixers. Don't use centralize water heater cause you will be heating water that you not using. Small tanks will just heat water that you want to use

talk to your sister. If she has any experience then she will know where to save and where to spend (the true value of a good consultant) and not just make fancy over design houses.

Do the out door plugs. Especially since your house is so big. You never know when you will need to use it. Think when you have garden BBQ and gathering, then at least you have power for your lightings and fan

Get it right the first time. It will be worth it in the long run.

Added on August 29, 2011, 12:01 pmDon't use solar heater for a house this large. Efficiency rate very low and the extra plumbing will cost a bomb.

Solar heater don't really work in country like ours. Not enough sun. Don't get confused with hot and sun. Here in Malaysia, especially KV, we don't get direct sun. Too much clouds and haze solar heaters are good when you have clear blue skies. We don't have that here so your solar heaters are running on their electrical heaters more than solar don't get conned by all the marketing. Understand the products.

Also for dry/wet kitchen, please plan what equipments you plan to put there. Some may require more than 13A plugs (15-20A) -ie. Oven, large fridge, cookers. Also don't forget plugs for hood and burners. Go look in you existing kitchen and see how much electrical stuff you have, that is how many points you will need.

Plaster ceilings- would depend on the design that your sis did. If the original design was opened then there would be no plaster ceiling. Ask her to give you a 3D sketch of the space and see if it is to your liking

If your sister is going for a natural look then no ceilings. Think - Kevin Low.
