Due to persistent grass damage like this,
which can take months to repair and regrow, we no longer allow flat bottomed fire pits at all, and raised fire pits and BBQ’s ( minimum clearance height 5 inches / 12.7cm ) with the use of a thermal matt to protect the grass below, such as this arrangement.
If you do not have such a protective mat, we have a limited number to rent or buy available in our Reception.
Use of stone slabs or bricks offer no thermal protection as they heat up and still transfer the heat into the grass.
