For The Children...
1. All Weather Surface Play Area
An all-weather play area is a real boon on wet Winter days and there's plenty of options to choose from. Mulch or chippings are an easy if dull option. A slightly brighter option is imitation grass. And increasingly popular are rubber mats which have the advantage of coming in a range of colours. These are all easy to look after. Just make sure that there is good drainage underneath.
2. Tricycle Paths
Even a small garden can rise to a fairly respectable tricycle path, provided it wends around the available space cleverly.
3. A Wendy House or Tree House
Every kid loves their own domain! These can be bought in kits and self-assembled.
4. The "Football Pitch"
Even a fairly small lawn can work. All you need is a set of goals and a hardwearing grass like Number 3 or a sports field grade.
5. Children's Garden
Older children will love growing their own simple vegetables and flowers. Younger children will be equally happy growing some plastic flowers or just taking on a little excavation project! Using raised beds can make these childrens' gardens more accessible and maybe a little less mucky.
