I just have two restriction only, not facing incoming road and not to have road curve towards the house. Corner unit preferably not to have odd shape land.

Ya, different people tell me different thing, so better avoid la if got choice of proper rectangle shape. I flip through joey yap book in mph last week, he said better to front shorter than back, so that can accumute chi or wealth can be accumuated at the back. But i think the house look better if front longer than back cause it make the house look like having big piece of land beside.
