Backyard
Trim around deck edge. This is how I would do the platform. One board trimming the outside. And then put river rock up against it. Use deck blocks with 4x4's sticking in them and then frame around the 4x4's.
Grey slab patio blocks in front of shed transitioning to a wood platform.
Potlights in overhang
Barn door
Deck instead of pavers and transitions right into shed.
bench
concrete borders
Side yard
