From research carried out by Friends of Colwick Woods group, and as seen in the photograph taken by Mr Alfred Woolrich in 1986 and recent photographs by Mr John Davies in 2007, we can see the inward slope of the now top layer of brickwork which leads us to believe the roof of the Ice House was of a dome construction. The entrance can be seen in the 1986 photo where a section of brickwork approximately 1 metre wide is missing. From measurements taken of the circular brick structure the diameter is 3.5 metre.
We have as yet to determine the depth of the structure, as only 1.5 metre of brickwork can be seen below ground level. The remainder is currently filled with soil and rubble (possibly the remnants of the collapsed roof). There is also a pipe which we believe extends from the base of the Ice House to a gulley, which allowed drainage of the melted ice.We believe the Ice House was constructed in the then grounds of Colwick Hall Estate, of which Colwick Woods was part. Research is still ongoing.
