議會表示，擴建二級保護劇院的計劃將有助於 "促進 "其未來發展。
工黨議員Sophie Connelly說，劇院 "會很高興其改善計劃被同意"，因為更大的演出可能會來到這個地區。
劇院經理里奇-羅斯（Richie Ross）以前曾說過，它不得不拒絕演出，"因為我們無法容納它們"，儘管需求是存在的，但它 "空間有限"。

The go-head to expand a Grade II listed theatre will help "boost" its future a council has said.
A new building, for additional dressing rooms, catering facilities and wardrobe space, will be built on its car park.
Labour councillor Sophie Connelly said the theatre "will be thrilled its plans for improvement have been agreed" as it bigger shows could come to the area.
Theatre manager Richie Ross hpreviously said it had had to turn down shows "because we couldn't fit them in" and although the demand was there, it was "restricted for space".
Ms Connelly, the council's portfolio holder for culture, said: "The Planning and Development Committee unanimously approved planning permission for new dressing room facilities to the rear of Ipswich Regent Theatre.
She added: "We are confident that these enhancements to our arts and culture offering in a positive way will boost the longer-term sustainability of Ipswich Regent Theatre as a destination venue."
