There is the main stage (with green room behind it) and an auditorium that sits over 200 people.

On the ground floor, there is a foyer, a box office, a workshop, the NTC Touring Company office and a small 'black box theatre' style performance/rehearsal space with some limited seating.

The Playhouse was originally built in 1925 as a 700-seat cinema and occasional music hall.

The NTC Touring Theatre Company bought the building and converted the ground floor.

The upper floor was leased out to The Alnwick District Playhouse Trust who re-opened the newly refurbished Alnwick Playhouse in December, 1990.
