Millboard Composite Decking in Chorleywood

A Millboard composite deck in Chorleywood started as a simple decking project which became a whole garden design. Inspirational and realistic decking design leads from the property across several transition changes into a natural garden. An abundance of insect and pollinator plants, winding paths, and a circular lawn.  An exciting landscape in a relatively small garden.
