For the side of the house. Sedum sarmentosum . "Whatever the name, this little sedum is fast-spreading, drought tolerant and easy to keep in check. It grows in the hot, full sun or in the shade. It doesn't seem to have any special soil requirements. In June, it's covered with tiny yellow flowers."
Might be able to use some construction rubble for walkpaths...in sunny spots, can fill in with a special herb...so we can "walk back through THYME." Believe it or not, two nurseries specialize in plants you can walk on: Stepables and Jeepers Creepers.
