Farm style houses are a revelation to the senses. They have a connotation of space. When we think of farmhouses, we immediately think of sprawling acres. Even if the house is small by those standards, it must have a quality front porch. It has dual functions. First, it allows a lot of sunlight, thereby creating a space illusion. Second, it lets people relax and share the mundane attributes of life lazing with a cold coffee for comfort. This is what saving of a lifetime should go into; peace for few moments.
Second thing is the bedroom. Ideally bedrooms for a farmhouse style plan are in the second storey. It is because, first storey is meant to be high traffic area. Farmhouses are more often than not, cut out in rectangular shapes. You can look for little different shapes as well. A walkout basement is ideal if you look to avoid stairs. May be the age is catching up a little.
