 Between 1814 and 1816 a chapel was built to Harrison 's design at West Hall , High Legh to replace an earlier chapel . This was a simple building that burnt out in 1891 , some of its fabric being incorporated into a new church on the site , St John 's Church . In 1818 the Right Revd George Law , bishop of Chester , asked Harrison to carry out work on the south transept of Chester Cathedral , which was showing signs of instability . This work involved building deep buttresses at the south end of the transept , and giving some attention to the gutters .
