Allan Crossan, who has owned the bar in Glasgow's Stockwell Street for 12 years, said the rebuild would be a "community" effort.
He said he would contact relatives in the new year for their input - and ask for their views on a possible memorial within the bar.
It came as an album featuring the band Esperanza, who were on stage when a police helicopter crashed into the Clutha on November 29, was launched to raise money for bereaved families and survivors.
The bands on the CD are calling for everyone to remember the people affected by playing the Esperanza song Be Brave on Friday at 10.25pm - exactly four weeks after the tragedy.
The album costs £5 and all proceeds will go to the Clutha Appeal Fund set up by Glasgow City Council.
All three of the helicopter crew as well as seven customers of the bar died in the crash.
Mr Crossan said: "It's overwhelming that all of these bands are coming together."
Gorbals-born Mr Crossan, 60, said it had been a very emotional time.
He added: "I'm going to write to the relatives just to see about the rebuild of the Clutha, which we have to do.
"But it's more than just me that's got to do it. It's got to be a community thing. Maybe someone will want to do something for their loved one so we'll try to do that."
Esperanza bass player Jess Combe said the mass tribute on Friday would be "poignant" because the band were performing Be Brave when the crash happened.
The 24-year-old from the East End said: "It's more of a remembrance and a consideration.
"It's a very poignant movement. The moment that it happened we were playing that song.
Band manager Gary Anderson, 46, who lives in Ayrshire, said: "We want to get this album out to help the people who have been affected."
The Clutha Sessions also features bar favourites, The Vagabonds, Rose Room and Cahoots.
