The Hidden Brewery, a Wiltshire-based microbrewery, has acquired its fourth pub, the Chough in Salisbury.
The brewery is growing rapidly, having also taken on the King's Arms in Thornford, Dorset, in October 2007.
The company also runs the Cornubia, in Bristol and the Bell Inn, at Wylye, Wiltshire.
The Chough will be the Hidden Brewery's largest pub, covering approximately 7,000sq feet over five levels, although only two levels will be open to customers.
Michael Woodhouse, from the Hidden Brewery, said: "The Chough is a very exciting place with an incredible amount of space, and we have lots of plans for menus, music, clubs, entertainment, Wi-Fi facilities and real ale, of course.
The Chough is situated in the market square of Salisbury and parts of the building date back to the 1300s when it was an old coaching house.
The Hidden Brewery's team plans to use the space inside and outside of the Chough to create a variety of different areas to suit different customers and times of day. One of the main evening themes at the Chough will be to host live music, including jazz, blues, folk and rock.
There will be a large lounge area with sofas, comfortable seating and an open fire.
The downstairs bar is to be refitted.
Upstairs is a larger restaurant area with original wooden oak beams and listed windows, and room to cater for private functions.
