how many sqft u want? RM150 to 175 u are good to go. legal fee is abt u borrowing money from bank?

I don't think U can build houses on an agricultural lot; u need to apply to convert the land usage to residential. Else every developer will buy cheap agricultural and build houses and earn tons of money. residential land is so much more expensive vs agricultural land.

Are you doing subdivision or partition?
When you do subdivision, a piece of land held under 1 title by 1 or more owners is separated into 2 or more pieces held under separate titles by the same original owners.
When you do partition, a piece of land held under 1 title by 2 or more owners is separated into 2 or more pieces held under separate titles by each owners proportionate to their share under the original title.

When you do either, you need to clearly demarcate on site plan the extend of the site boundary after the subdivision/partition. Then from that point on, will need to allow setback from boundary before deciding where to put your house.

250-300 psf excluding furnishing for a nice detached house in KL/Selangor.

Yes the house looks minimal but it has to suit the family living in it. But not to my personal liking. It doesn't look very well thought-out. Things looked very big and give a sense of blunt. But I haven't see the plans and seen the inside, which may change my view.

Sometimes, where we want to make things look simple and minimal, it will involve a lot of non-standard details, which may or may not escalate the construction costs. Some people may not feel like 'home' when you have a box like this; on the other hand, some people hate the tropical pitched roof and prefer flat roof (a box).

For detached houses I design for my clients, if they have no preference at first I always design for the climate (pitched roof, deep verandah, louvres, cross ventilation, etc.) and then refine from there. Some liked it, some don't. Just the way of life.

You see that cantilever? It is quite substantial, and therefore may be a little bit expensive. You can have very small but very nicely designed and finishes at a high price; also you can have a very large dull box at a cheap price. There are so many different approaches to it, ultimately depending on what you can afford and what you want.

the cost can be as low as 125 psf. just need to use not expensive material. example instead of use marble u can consider use tile selected from shop in jln Ipoh. save a lot.

oic. ya all normal material. another way to reduce cost is reduce temporary work more and with a good buildability design. meaning not those artistic kind of design like slope wall etc.

u mean want higher ceiling? or pitch roof high gradient?

ic. cost would be higher for roof tile. not just the tile, the structural support component also. but those are not expensive thing though

In tropical country like Malaysia, higher pitch roof is ideal to discharge the rain water quickly.

I think if you go for 25-30 degrees pitch will be good enough.

Please provide more details.
Landed, strata development, or subdivide land or ???

if the plan is approved, normally PTG may take few months to issue the new title.
