The New Theatre Royal, Portsmouth is a Grade II*-listed theatre, originally designed by Charles Phipps as a variety theatre and subsequently remodelled by Frank Matcham as an opera house. Phase I comprised the refurbishment of the historic, predominately cast iron front elevation, and remodelling of the auditorium to include a thrust stage, stall seating and bringing into use the grand circle and upper circle levels. 

Studies were undertaken for further phases of work, including the building of a new stage house, improved foyer spaces and administrative offices and a completely new build extension to include a studio theatre, rehearsal studio and backstage accommodation.
