NorthWestern Energy has unveiled plans to replace its 40 E. Broadway St. general office building in Butte, US, with a new $23m building.
The new 110,000ft², five-storey building will be constructed on the north-east corner of the intersection of Park and Main, currently the site of the publicly owned Heritage Plaza.
As part of the plans, NorthWestern Energy said it has started working on a development agreement with Butte-Silver Bow local government, which may lead to the construction of the building.
Under the deal, NorthWestern Energy would assume ownership of the plaza property, while Butte-Silver Bow will own the company’s existing building at 40 E. Broadway.
NorthWestern said it is also planning to work with Butte-Silver Bow on the development of a parking structure in Butte.
Construction of the new building is expected to start in the first quarter of 2014 and complete in late 2015.
Montana-based Mosaic Architecture has designed the new building while NorthWestern Energy is planning to select a general contractor for the building after signing critical agreements.
The existing building accommodates 200 NorthWestern employees in a variety of functional areas and includes five different structures, as well as a top floor, which was added in the 1960s.
NorthWestern Energy CEO Bob Rowe said the company has been working for several years to develop options for its existing general office building, which has reached its functional limit.
"It is actually five connecting buildings of varying structural types, some that date back to the early 1900s," Rowe said.
"We intend the building to be appropriate to its historic surroundings, efficient, in compliance with all codes and requirements and conservative."
