Nice option too container/raised bed herb gardening. Some of these herbs won't stay small and cute, so would need to plan to plant the taller ones in the upper tiers and maybe with a little bit larger growth area.

Nice raised beds and garden layout (Would work as sub-irrigated beds - also compost at center of each angle would be nice, or add some worm towers at each end.) @ its-a-green-lifeits-a-green-life - Gardening Layout
