We'd like to bump out the front gable wall over our half-walled front porch to gain six foot room additions in two tiny upstairs bedrooms. The porch has three steps up, and is as wide as the house. Will we need a stronger foundation under the porch for the weight of the room additions?
Our granddaughter is coming to live with us. We'd like to take the seldom-used fourth upstairs bedroom and divide it into a no-frills bathroom (store-bought shower, sink, toilet) and a walk-in closet for her. The bathroom would be right over a downstairs bathroom. Are we talking $15,000? $25,000? More?
