We are building a boardwalk under the house, so we have access all the way around. The house is built on a slope, so it can be a bit difficult for older relatives to get around and down to the back yard.
It's taking time because we only do something on it every couple of weekends. It's coming along though...Now the joists and framework will go down (like the steps in the bottom photos), then the decking boards will finish it off. It connects up to the deck at the clothes line.
When we have this done, we have plans for platforms and decking to come off the other side of the laundry deck. These will attach to some more steps down to the back yard.
