Nordblom Co., which is pushing to redevelop part of Northwest Park in Burlington, will begin demolition next week by razing an office building for future development.

The Burlington-based firm is forging ahead on the project, approved in 2007 but stalled when the credit markets froze as the recession set in. The site along Route 128 and Middlesex Turnpike was approved for up to 2.2 million square feet of office space and 600,000 square feet of retail and was approved in 2007.

While no tenant has been signed for a build-to-suit on the site, Nordblom will demolish 174 Middlesex Turnpike to show it is ready for potential tenants to come forward. Todd Fremont-Smith, Nordblom’s senior vice president of development, said the company is actively seeking potential suitors for build-to-suit options.

The company started its efforts to begin office development to coincide with an almost done deal to lease a 30,000-square-foot space for a Kings bowling alley and restaurant along the 300,000-square-foot Third Avenue. Fremont-Smith said the complex will be "an environment … that will truly be an alternative to going [to Downtown Boston] for dinner and entertainment." The site includes plans for high-end housing and a boutique hotel.

The area will be lined with restaurants, with 10 liquor licenses available. It will be anchored by a 140,000-square-foot Wegmans supermarket. Demolition will soon begin to accommodate 300,000-square-feet of retail space through Third Avenue’s first phase of development, which is slated to start in the spring of 2012 and conclude in the fall of 2013.

Third Avenue will serve as a core element of Nordblom’s broader Northwest Park redevelopment plan. Northwest Park is a 4.6-million-square-foot, mixed-use, mega-development that includes two distinct office campuses in addition to Third Avenue. Northwest Park is the largest mixed-use, fully-permitted project currently under construction in Massachusetts, according to the company.
