The first task was to plan out what we wanted. As the garden was quite large, and south facing we thought we would make the most of this with 2 large patios at opposite ends of the garden. As we kept Budgies in the aviary we wanted to make sure this was on a concrete base (it was on the lawn at the moment) and also to incorporate a rabbit pen area so they could roam about a little during the day.
The plan was that we would construct a raised bed, using all of the soil that was dug out for widening the paths and making the patios. This would need a small wall building in order to retain all the soil. The wall needed a footing and so we marked out its length and then created a concrete trench with which to build the wall on.
