Traditional Box Sash Windows London

Did you know that the traditional box sash window has been around since the 17th century? Amazingly the cord and lead weight design remains almost unchanged with spiral hung sash windows being a more modern development.  Victorian timber London sash windows are a key architectural feature of a number of areas including Kensington, Islington and Hampstead and conservationists are keen to retain the heritage features, which is why we work closely with them to ensure that the patterns and designs are precisely copied.
