I built this set of landscape stairs to provide access from the driveway to a finished basement. The steep bank had been filled with boulders and topped with large stones. The photo above is the finished project. In the photo below you can see the dangerous rocky temporary path that the owners had been using. Design and permitting took about a day; digging holes (and removing a lot of big rocks) for the concrete platforms and supporting Sonotubes took another day. The carpentry work was three days.
