Small ponds can vary in size and take quite a large amount of planning and building. They are commonly found in suburban and city environments and built from either butyl liners or formed from concrete or brick work. The overall design can be traditional and formal or more organic and wild. Maintenance should be considered within the design scheme. You may also want aquatic planting and fish within the pond? The two pictures featured below have been built within gardens using concrete and brick work. See the diagram on construction to see in more details how the ponds were built.
