A popular tourist destination on the Suffolk coast is to become a "creative campus" that aims to match the vision of renowned composer Benjamin Britten.
Snape Maltings, a collection of retail units, galleries and residential flats, is being sold to Aldeburgh Music.
The charity organises the annual Aldeburgh Festival and runs the Snape Maltings Concert Hall.
Roger Wright, chief executive, said: "Owning the whole site opens a myriad of possibilities."
The purchase is being made with the help of £2m from Arts Council England and the "receipt of an individual donation".
The sale price has not been disclosed.
Mr Wright said Aldeburgh Music's plans for Snape Maltings would fulfil "Britten's vision for a creative campus with a new level of public engagements".
"I look forward to an open discussion about the way in which partnerships can develop the site's potential for audiences and the arts in general," he said.
Britten, who was born in Lowestoft, bought an old mill in Snape in 1937 after being left a legacy by his parents.
He rented the site's largest building after Snape Maltings was purchased by George Gooderham in 1965, and went on to create the Snape Maltings Concert Hall.
The site has been extensively renovated by the Gooderham family over the past 50 years.

The sale is expected to be completed on 18 March.
