'It also makes more sense to transform outdoor pools into bio-swimming pools than to renovate them at high cost.'
And swimming ponds can be less expensive to build and maintain than standard swimming pools, Littlewood explains. The Austrian-based company Biotops has built more than 1,000 swimming ponds in Europe alone. And the finished product is often easy on the eyes, with beautiful plants edging clear, open water.
Littlewood, who for the past 10 years has based his landscape architecture practice on 'holistic ecoprojects,' says natural pools do more than help the environment; they can also lift your spirits. 'If you are living a holistic lifestyle, eating organic produce, using alternative medicine, drinking spring water, then it makes sense to avoid swimming in a pool containing chemicals,' he writes, adding that 'to be able to swim in natural water is sheer bliss.' sheer bliss.'
