Delux Chicken Coop: this is the cutest! Very cozy chicken coop. I'm not entirely sure if it's authentic or if it's a children's play house. Either way it would makeshift as a lovely summer guest house if extra space was needed.
you could add some fish to your water reclamation tank for a small aquaponics system. Grow a few plants to feed the fish and this forms a closed system. There is no need to fertilize, the fish do it for you! Permaculture at its finest!
Ideas for Edging Planting Beds ~ Use very large rocks as edging. Large rocks help in keeping weeds out of beds and lawn encroachment into beds. Small rocks and/or stones move easily and are an impediment in mowing lawn close to beds.
