this one I grabbed from sulit.com.ph
this one is from cmbuilders.com (they have plenty of Zen type house designs) I am actually tempted to inquire for their prices but I stopped myself..not now but maybe I'll get to ask for their quotation someday)
this one from ayosdito.ph
this one is my favorite because I love the simplicity and the over all look of it.
