We live in a small ranch-style house quite a ways off the main road. Our driveway is routed in such a way that it winds around the pasture and comes up at the back of the house. When we first moved here we thought we would make a new driveway coming straight in from the road to the front of the house, but after 16 years, we've come to appreciate the fact that we can see approaching visitors well in advance of their arrival if we just leave things "as is." We'd like to do an addition to the house that would make the back look more like a front. I've got in mind a deep porch on the left end of the house, with a small sunny room to be the foyer or entryway. I've got this simple floor plan sort of figured out, but I can't get roof lines straight in my head. Does anyone know of a good site that would show you examples of what various additions and roof lines would look like on a plain rectangular house? Whatever we do, it must be modest and unpretentious in order to fit in with the rest of the house.
