After looking at Australia property, I wonder why MY seldom build single storey houses? Except for the low cost housing. I hope to have a condo and a nice single storey landed when I retire.
A single storey house like those common in Australia would be more appealing to me, as I don't have to climb the stairs when i am old and frail of course the house has to prove that it is not prone to flash floods.
My relatives in their fifties who stay in terrace houses always complain about climbing the stairs, some even moved to the small room on the ground floor.
Because margins are higher for double story houses, and developer get slightly higher income purchasers. Btw, if you're not Malaysian, you don't qualify for 1 story house in m'sia. just sayin'.
