Likewise why not have a water feature of some kind? There are loads of great things you can get for a garden and these are all able to change the feel of your garden in many positive ways – they create a shimmering and sparkling lighting source and they create a trickling sound that is highly natural sounding as well as being relaxing and peaceful – it's like having one of those 'sounds of nature' CDs on repeat and just chilling out to it.
A swing bench is also something many people get pleasure out of. They're great fun, a great novelty, and the fact you have them means that you can relax by cradling yourself.
Why not get decking? Decking is natural looking, soft under food, and a great alternative to walking on the grass. It has a very minimalist feeling and is very zen and it would match a water feature or a hot tub perfectly.
There are plenty of great ideas you can bring to your landscaping, so think outside the box and discuss the ideas with your landscaping companies.
