There’s only one way to build a Koi pond, we say:- Designed 100% correctly and built 100% correctly. We built one at our office, watch the process here. Summer meetings are held dangling our toes in the pond. We found great inspiration from Peter Waddington online. Expert stonework by Rob Mackenzie. Granite and sandstone have been cut to fit tightly and we love the sound of the waterfall all day long up to our offices.
