How much does it cost to design and create a green natural playground? There is no straightforward answer to this question. We know of green natural playground that have been realized by volunteers and re-use of materials, thereby substantially reducing the costs. But admittedly, these examples are more of an exception. Apart from materials and working hours, you have to budget for other costs related to preparation, design and publicity, organisation/planning, fundraising, risk analysis/security check, maintenance and use.
