In the sensitive Sloane Square area this existing hotel was demolished and rebuilt as a residential block. Five floors were demolished and replaced by seven inside, although the front elevation still had to retain the existing format. To replicate the existing chimneys GRC panels were installed on a steel frame fixed to the main roof members. All components were cast in handspray GRC including octagonal chimney pots. The alternative solid cast stone would have required back propping through two floors to carry the additional loads and would have imposed significant lifting and programme related problems.
