Description

A depression has appeared in the communal grounds of 1 Home Barns South Gloucestershire; a development of 20 houses converted from warehousing in 2008. The original warehouses were circa 1970. The depression is 2.5 m * 5m and approx. 50 cm deep. There are cracks in the soil visible on one side of the depression. There has been irregularity in the area of ground since I moved in in 2010 although it has increase in scale significantly over the last winter. There is no sign of any irregularity in google c. 2005 or Bing c. 2009. There is a SUDS approx. 20 meters to the east that is fed from the roofs of the buildings. The area has been taped off.
