Developers of a proposed restaurant, music venue, retail, apartments and garages surrounding the future 21c Museum Hotel say they’re prepared to start construction of “everything at once” at the unveiling Thursday of their plan.

Plans for the music venue and restaurant at 901 W Sheridan, to be operated by Graham Colton and Brian Bogert, and demolition of several structures along Main Street and Sheridan were approved Thursday by the Downtown Design Review Committee.

A presentation by Mark Beffort, Andy Burnett and Zach Martin of plans for housing and retail, meanwhile, got a positive response from the committee, though a formal application isn’t expected until August. After the presentation, Martin indicated final planning for “The Residences” is still ongoing, but he expects the work to transition from conceptual to development design phase.

“The apartments and retail are still preliminary,” Martin said. “There are a still a lot of hurdles to overcome.”
