The theatre was opened in 1983 shortly after the Montgomeryshire College of Further Education (now Coleg Powys) was built

The auditorium seats up to 556. Note that for larger audiences (+508) the forestage cannot be used. Two fixed balconies run from front to back of the auditorium. The central seating unit of 384 seats can be withdrawn to leave a clear floor area of some 12m x 12m. 100 loose seats are available.

A loading-bay "door" leads straight onto the stage right wings. Access is good for all types of transport. Bay width is 2.5m, height from outside ground level is 1m, doors are 3.5m high

A stage door on the south side leads to the two-story dressing room area.

There are two principal dressing rooms and one Chorus on the ground floor. A similar Chorus/Band room is situated above on the first floor. One first floor office has now been reclaimed as a dressing room, making five in all. Toilets and showers are situated on both floor levels. There is no ‘green room’. A small kitchen area is available on the first floor landing but unfortunately no cooking facilities are allowed here.

Access to the rear of the auditorium during performances necessitates going outside the building.

Front of house consists of the box office and bar and a foyer & coffee shop, shared with the college, is also available. Merchandising is usually found most convenient on the stage left side of the auditorium, under the seating unit or else in the foyer on busier nights.

The building operates a no-smoking policy. Smoking is permitted only outside. NB. Smoking as part of a performance is now also banned.

Car parking is free and adjacent to the theatre. Wheel chair access is possible to the stage area, the auditorium floor and all front of house areas. There are no wheelchair-accessible toilets backstage.
