The reason why the new building was not used by the Greshambury Institute might have been as the result of a terrific fire one night in November 1895 that burnt the Gresham Paper Mills to the ground. The fire left only a pile of twisted metal and brickwork.
Today, all that remains of the Unwins in Chilworth is the original cottage that George Unwin and his family lived in and a grass covered slope down to the river. The only bit of equipment that is left in the area is one of the paper rollers which was rolled up the hill after the fire to Blackheath village where it can still be seen on the cricket pitch today.
