So much can happen on an exterior...trim, exposed rafters, doors, windows, siding, stone, brick, stucco, roofing, gutters and downspouts....hire an architect or a design/build firm to help answer these questions prior to building....like hiring an interior designer for help with furniture, these professionals will help decide the style of the exterior of the house and how that style interacts with the function of the house.
