'Living' or 'green' roofs are growing in popularity as they are attractive and good for the environment. It is like a living carpet made of low growing succulents - plants with thick fleshy leaves and stems, which makes them particularly suitable for growing in the inhospitable conditions such as a roof.

Little maintenance is required. The varieties of sedum used are able to withstand periods of low rainfall, strong drying winds and sun, and they grow with the minimum of growing medium. After a good watering when the plants arrive, they should not need any further attention. There is no need to feed or water the plants thereafter.

Sedum likes sun so it will flower more readily if positioned where it will receive sun for at least part of the day.

The box is untreated. Treating it will not significantly add to its life. However, if you do want to treat it, please use a boron based preservative which is water based and do not treat the inside of the bird box.

The nestbox is handmade in the Pathways workshop in Oxfordshire. The boxes are made using traditional woodworking skills and locally sourced FSC approved wood, much of which is donated by local businesses.

The hole has a diameter of 28mm, which is favoured by small garden birds. The sedum tray is 21cmx21cm. The Height of the box including the tray is 25cm. The bird box is 14cm wide and 16cm deep.
