IF your idea of a farmhouse on the outskirts of a bustling metropolis is that of thatched roofs,chicken scratching dirt in a backyard overrun with weeds and antiquated lamps casting sinister shadows in the night, banish the thought. The farmhouse today is a luxury in marble and stone set amidst landscaped gardens and orchards. A breath of fresh air after the noxious existence that is city life. Originally intended as a quick getaway over long weekends, improving facilities have turned many farmhouses into permanent residences, with a lot of thought and passion going into making them dream homes.
