Prospective co-owner Brad Ziegler isn’t sure why the “For Sale” sign is still on the door at the Masonic Temple.

Ziegler and partners Jerry Johnson and Jim Womack are still planning to turn the 92-year-old building at 1001 Mass. into a concert venue.

The Masonic Temple, built in 1911, is being transformed into a music venue. Owners hope to have the building fully operational this fall.

The building was scheduled to transfer hands April 15. Johnson said renovations would begin the next day.

“It’s an enormous project and we are working hard to get it open as soon as we can,” Johnson said.

The goal is to have the building fully operational by the fall. Johnson said he anticipated being able to accommodate small events earlier than that.

“There is quite a lot of interest in holding wedding receptions there. We have had quite a few calls,” he said.

Plans are in the works for a grand-opening bash. The event would feature a concert and theater opening.

“We want to do something special,” Johnson said.

A list of possible candidates to perform at the opening has been decided, but he is keeping the names a secret.

“It’s a beautiful, historic building and we want to bring in acts that are suited to that,” Johnson said.

With its stage open to a dance floor with side and balcony seating, the venue promises to have shows on scale with Liberty Hall. The building’s architecture will remain the same, but technology updates will be made.

The second floor of the Masonic Temple consists of a balcony with additional seating that projects over the hall floor below.

Johnson said a decision had not been made about what to do with the pipe organ dominating the balcony’s back wall. Because the organ was rumored to be an original Reuter piece, Johnson was considering doing something with the Reuter Organ Co. or donating it to a church.

He said the building’s new purpose fits in nicely with its history.

“For about six years in the late 1800s, it was actually a music hall,” Johnson said.

So far there has been a good response to the idea.

“We are excited about opening it up so people can see something they haven’t been able to see for 90 years,” Johnson said.
