"We've done some sound-proofing between the front and rear of the building and are still trying to decide how to operate the back bar without causing problems for residents."
Mr Sheahon has recently returned from London to settle back in his home city.
He said during his travels he listened to great bands at some of the world's top venues and he was trying to bring the best of that together for Wanganui.
"Stellar Restaurant and Bar and Spirit'd seem to be doing a great job of providing entertainment for the young people, so we're addressing the slightly older folk with easy listening playlists, a relaxed atmosphere, and strict adherence to the new licensing laws.," Mr Sheahon said. "But we'll not discriminate against the younger folk in any way shape or form. We consider attitude and friendship to be the yardstick rather than how old someone may be."
He said the rear of the building was definitely in his plans once planned earthquake-proofing was completed.
"At this stage there is no definite start date but July has been mentioned as a possible beginning," he said.
Mr Sheahon said his vision was for the riverbank carpark section to become an upmarket beer garden with less emphasis on live music but more on well prepared food.
"If there was to be any music it would be of a quiet, acoustic nature, finishing at a reasonable hour in order to appease the lovely folk who live on Durie Hill.
"I can assure them that all noise from any section of our premises will be strictly monitored and acted on accordingly."
While the Riverside Bar is his first venture into the hospitality business, he said he was fortunate his team were all "very polite, friendly, hospitable" people.
"Their past experience in the game is totally invaluable to me," he said.
Mr Sheahon said good, wholesome pub food was available and although rather basic at the moment he said they aimed to "up the ante" once the kitchen area is covered of as part of the earthquake-proofing.
