Ideas for adding a natural pond or swimming pool to your garden, whatever its size and inspiration for hard landscaping materials
Water is an asset in any garden. Water features can mask noise pollution and create a strong sense of place. Larger bodies of water can tie the garden to its exterior landscape and smaller pools and rills can enhance the atmosphere of an outdoor space. Ponds are becoming ever more popular in gardens. They are a calming influence and, at their best, look entirely natural.
But, whether you want somewhere to swim, a natural pond or reflective pool you’ll need hardscaping to match and below you’ll find practical information on how to line your pond and planting advice. Below are three inspiring gardens that have incorporated a natural swimming pool or pond into the design in a beautiful and considered way demonstrating that there is a water feature for every style and space.
For a slightly different approach, have you considered an outdoor bath? We’ve found the best bath tubs to install in your garden – and some luxurious holiday lets to experience the joy of an outdoor bath first.

How do natural swimming pools work?
Practical considerations for introducing a pond or pool into the garden from garden designer Andrew Wilson
- It is important to disguise and cover the liners as they emerge from ponds and pools. Firstly, this is unsightly and, secondly, exposure to sunlight can weaken and damage the material, which becomes more prone to leakage.
- Keep pond shapes simple so that excavation is easier. Introduce planting to create visual interest and a naturalistic quality. Complex shapes often produce shallower and narrower water, which will silt up and warm quickly in sunlight.
- Butyl rubber is available in sheet form but can be glued or welded to create large-scale pools. With larger ponds, be aware of the local water table. If this varies dramatically, pressure from a rising water table can force water out of a lined pond. Liners can then be vented to allow pressures to be equalised.
- Don’t install lighting within a pool. This will reveal the lining, wiring, pump and detritus within the pool. Instead, light objects or planting on the far bank. Their reflection will be seen on the surface of the water after dark creating a more dramatic result.
- Existing streams and rivers cannot be dammed or altered. The Environment Agency is responsible for all watercourses and must be contacted before any work is considered. In general, create separate, self-contained ponds that do not overflow into nearby watercourses.
- Sunlight can create problems in ponds and water features in terms of solar gain, but it would be more problematic to site water in heavy shade. Sunlight brings life to water but does need to be controlled with careful planting allied with a good pool size and depth.
Landscape designer and architect Bart Hoes five key points for designing a pool garden
- Materials
Using concrete when building a pool gives you an unlimited freedom of design. For the area around the pool, Bart recommends using splinter-free decking, which can be cut into any shape and it does not get as hot underfoot as tiles. - Colour
A grey finish on the pool’s inside provides a much more coherent and natural look in a verdant garden than the standard blue. The darker you go, the more of a ‘pond’ rather than a ‘pool’ effect you get. - Planting
The old adage of ‘no deciduous trees around a pool’ no longer applies, thanks to technological innovations, such as skimmers and robot vacuums, that get rid of leaves and debris. By bringing planting up to the pool’s edge, you can alter even further the visual impact of the pool’s shape. - Shape
Although your plot may dictate the pool’s area, it does not necessarily dictate its shape. Nowhere in this garden do you feel you are on a triangular plot. You can make a round plot look rectangular and vice versa, by choosing the pool shape you like and then blurring the outer boundaries with shrubs and trees. - Layering
When designing a pool garden, think vertically. The water surface is always flat, so is the area surrounding the pool. If you line that with walls of tall trees, the effect is one of a box dug into another box. Plant a transitional, medium-height layer, such as shrubs or multi-stemmed trees.
Garden designer Frank Heijligers’ five key points for planning a mirror pool
- Position Think carefully about the most suitable position for your pool. Ideally, you want a spot where you’ll be able to sit by it in summer, but where it will also form a relaxing focal point from inside the house – this is where you’ll probably be looking at it for much of the year. Bear in mind the main views from your home and also the architecture of your house.
- Safety A sunken mirror pool generates a wonderful reflective and relaxing effect, but isn’t always practical when you have very small children or pets. To avoid accidents consider a raised pool. Corten steel or zinc troughs can look very effective.
- Design A mirror pool requires less maintenance than a natural pond, but it also demands well-designed furniture that’s both comfortable to sit in and is interesting to look at.
- Cost Installing a mirror pool can be expensive. Depending on the size, materials and whether or not you want it to contain fish, it can cost from around £180 to the tens of thousands. You can reduce costs if you keep the design simple and, like Paul, you’re happy to dig it out yourself.
- Size A pool is an asset in any garden, large or small, and can also enhance the sense of space – a rectangular pond makes a small garden look bigger. Dare to make a statement and don’t shy away from a generous size.
