Scroll forward through photos

At the top of the building the Wren Room is a large, open room with fantastic views from its north and south facing full-height windows. There is no fixed setting here so the space and seating can be configured however you wish, for events ranging from board room meetings, theatre-style presentations and drinks receptions. There is the added attraction of a roof terrace, onto which the north facing windows open out. Hiring this room in conjunction with the smaller Hawksmoor Room as a breakout or catering area allows you and your delegates to enjoy the exclusivity of the entire Sixth Floor.
