A Fairfield commercial project in the works for four years is starting to take shape.

Walls are rising on a 50,000-square-foot Whole Foods grocery store being built as part of the Kings Crossing Shopping Center at the corner of Kings Highway East and Grasmere Avenue. The development is on the site of the former Handy & Harman factory. The project is expected to be completed sometime in 2011.

The 11-acre property at 1770 Kings Highway East was purchased from Handy & Harman by a partnership of Summit Development and Greenfield Partners in 2003 for $8 million. Handy & Harman, a metals manufacturer, spent nearly $20 million on remediation and environmental cleaning over a five-year period as a condition of the purchase by the developers.

In addition to the Whole Foods store, CVS has already signed a lease on a nearly 13,000-square-foot store. There will also be a 23,000-square-foot in-line retail space that is still open to lease.
