A small Cornish cottage in a riverside village, located in a conservation area. All but one of the sliding sash windows here were replaced, maintaining the proportions like for like, and incorporating double glazing. Richard liaised with building control to agree a glazing specification which enabled the retention of section sizes and glazing bars in character thus not compromising the external and internal appearance of this cottage. All of the rear elevation casement windows were re-designed by Richard and produced to the same double glazing specification as the sash windows, thus not disturbing the internal reveals.
