Deltic Group is investing £850,000 in converting its Plymouth site.
Oceana on the Barbican Leisure Park will trade until 15 October before reopening as a Pryzm club and Steinbeck & Shaw late night bar on October 28.
Przym will be the main arena ‘showcasing the latest light and sound technology and frequently hosting international guest DJs and celebrities’ the group said.
R&B chart tracks will be played in separate room called Curve, while the Shoreditch inspired Steinbeck & Shaw - featuring walls of graffiti art, skull imagery, modern sculptures - will offer an extensive range of freshly prepared cocktails and a premium drinks range of spirits, wines and craft beers whilst playing an eclectic mix of music.
In July, Deltic opened the fourth of its Steinbeck & Shaw bars, in Cardiff, after a £300,000 refurbishment.
Earlier this year Deltic chief executive Peter Marks told MCA that Steinbeck & Shaw was likely to be a regular feature in refurbishments of Pryzm sites.
