Thursday, 15 January 2026, 9:30 am - 11:00 am

Join the City Architecture Forum on January 15th as we tour this historic early 19th century riverside building which has for many years been occupied by HMRC and closed to viewing.

Joss Brushfield of Jastar Capital will introduce the 180 room hotel scheme and lead the tour.
