My garden is complete.
Wooden frame screwed into my neighbours wall and extended with PVC utility pipes to form a side. Open on both sides to let the air flow trough.
Excess foil is rolled up at the bottom. If it gets' damaged this year I can flip it over next season.
Waiting for a storm to check for any weakneses, but this is my 4th year with this design, I should have everthing ironed out now.
