The plan had been to build a natural swimming pool, but we quickly realised that we didn’t have enough space, or the funds to build one, so settled on the idea of a pond that we can sit in.
Luckily, the only available spot for it happened to be the most naturally placed, and easiest to construct on, a mini-cutting running away from the house. This meant that we could get away with building retaining walls for the water, rather than having to dig down into very rocky ground.
