Institute of Chartered Accountants Gets 21st Century Tech Upgrade Jul 16, 2018 Commercial Integrator Europe | Jordan O'Brien The London offices for The Institute of Chartered Accountants in England and Wales (ICAEW), One Moorgate Place, is a grade-II listed venue in the heart of the city. It has over 20 rooms which can accommodate almost any event or conference, the largest and most impressive of which is the Great Hall. The building comprises two parts, both of which fall under the Grade II listed building status. One dates from the 19th Century and has its original stained-glass windows on display and Victorian ceiling murals in the meeting rooms. This is linked by a marble stairway to the more contemporary building, erected in the 1970s, which contains the Great Hall.
