Northampton theatres delay reopening

Royal & Derngate has been forced to delay reopening as investigations continue into the safety of concrete used in its theatre foyers.

Managers at Royal & Derngate in Northampton have announced that both of its theatres will continue to suspend performances until 8 October. They said the closure will allow for the completion of the “final phase” of investigations into building materials found on the premises.

The venue was forced to close on 4 September after reinforced autoclaved aerated concrete (RAAC) was discovered in the foyers, raising safety concerns and prompting an investigation.

The material, a lightweight form of concrete, was used in the construction of public buildings between the 1950s and the 1970s. It is described as “much weaker” than traditional concrete by the Standing Committee on Structural Safety.

The venue’s Filmhouse was able to reopen on 18 September after access to the space was adapted, and a temporary box office was set up in a nearby pub.

Managers had hoped that performances in the theatres would be able to resume by the end of the month.

“We hope to be able to make further announcements very soon about our reopening schedule as we complete the final phase of necessary building investigations,” a statement on the venue’s website said.

“We are contacting ticket bookers directly about rescheduling performances, and we thank customers for their continued patience and support.”
