This garden in its entirety, including the gravel paths, is approximately 30 ft. x 30 ft. Generally we will design raised vegetable beds 3 ft. - 6 ft. wide so you can easily reach across without stepping in your soil. Gravel access paths are usually 2-3 ft. wide with some larger open areas for a wheelbarrow to fit through.

i am wondering what material is the wood , to be more durable... please let me know. Thank you, Miha

It's cedar. If you're worried about durability you could also line the wood with plastic.
