Hi! We've got a small space in our paved courtyard we were hoping to turn into a grass area. The space is about 3m x 1.5m. We're currently thinking of getting some timber sleepers to make a garden bed frame, and then filling it with rocks (for drainage), soil and topped with some turf. Will this work? How much/how deep do we need the rocks and soil to be? Also, where could we possibly get such a small amount of turf - everywhere I've looked has a minimum amount of 30sqm! Based in Melbourne inner east.
Note: courtyard is mostly shaded
Any advice welcome - total newbie when it comes to landscaping
