A topping out ceremony has taken place to celebrate the latest milestone in a £5.5m scheme to overhaul Watford Colosseum, Hertfordshire, which is due for completion later this year.

Work has included the construction of a two-storey, glass-fronted foyer, which houses the venue's new café bar and the Forum restaurant, as well as a customer lift. A revamped auditorium with retractable, loose and fitted seating for up to 1,400 guests and the installation of new sound and lighting systems are also included in the scheme.

Kier London has been selected to deliver the work. Operations director Normal Elliott said: "Work has been progressing really well and we are excited to have reached this milestone." Dorothy Thornhill, elected mayor of Watford, added: "The improvements are being delivered in budget and on time."

Owned by Watford Borough Council, the venue is operated by HQ Theatres.
