We don't have the same ethical stance here about building on paddy land as it seems in bali...but i agree, do not build on it unless you really have to...only so much land on earth after all......build around it and include it where possible.
We have the equivelent....conversion of are to rai....or vice versan actually...if I have the conversion correct...circa 112 are...all of it rice fields and I had designed a house to sit smack bang in the middle, on stilits and the fields become the landscaped garden.
Didn't quite get around to it, but now currently building a shed on it to house all our crap while we leave this place....so we enroached on circa 180sqm of rice land to build this shed still surrounded with rice land.
Wonder if Indo and Bali has this same fixation as here to 'raise' the level of any land bought with fill by about 1m at least....happens everywhere and is both an eyesore and a nightmare.
