In 2008 planning permission was granted on appeal for a new canopy to provide protection and shelter for the plants and customers across part of the open display area. The canopy measured 780 sq m and took on a rounded form rather than the traditional pitched roof greenhouse appearance.
The application was refused on the basis of the height and colour of the canopy and the impact this would have not only on the North Downs Special Landscape Area (SLA) but also on long range views from the Kent Downs Area of Outstanding Natural Beauty (AONB). The inspector determining the appeal disagreed stating that the canopy had no detrimental impact upon the openness of the SLA and would be barely noticeable in long range views from the AONB.
Planning permission was again secured in 2010 for a larger canopy of 915 sq m with the same rounded form, height and construction as previously. This application sought to remove the existing shade structure for plants and was approved by Maidstone Borough Council in February 2010, the principle of the canopy having already been established.
