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.

Send the length and breadth dimension as it isn't clear in the given drawing. The dimension for the left side bathroom and the kitchen are not practically possible.
