Developers have announced plans to transform the former production floor at London's old Kellogg's plant into office space, a fun park and a craft brewery.

Once complete, developers say it will feature North America's largest indoor ropes course, with ziplines, a trampoline park as well as go karts, mini golf, escape rooms and an arcade. 

Developers are calling the 170,000 square foot entertainment hub "The Factory."

"The Factory is named it for a reason," said Dan Cassidy, one of the London-based developers behind the refurbishment of the Kellogg's plant. "We want it to look very rough and rustic and commercial in nature."

"The concrete walls you see are the concrete walls you're going to see when we open," he said. 

Silverstacks Brewery

The new development will also include an office tower, located inside the old Kellogg's corporate offices located near the front entrance of the sprawling three-acre former industrial property.  

Developers also announced the inclusion of a craft brewery, which will be located near the heart of the former Kellogg's complex. 

Silverstacks Brewery will be run by the Tobermory Brewing Company with plans to open a restaurant once the brewery is up and operating. 

Today's announcement is the first of three phases and developers said they expect phase one to be finished by early 2018.
