I designed the stairs so that the new stringers fit over the concrete (11” treads, 7.25” rise). The new railing matches other existing railings on the house and the bottom of the rail is carved so that you can swing around the corner. The new deck will be built on the next trip (to Atlanta) and will be 7.25” higher, just a little below door level.
Generally, bad concrete stairs require a jackhammer and these were really bad.
