Larken Associates’ Echo Executive Plaza is now 100 percent leased after signing two long-term leases totaling more than 5,300 square feet.

The property, which is an office park adjacent to the Echo Plaza Shopping Center at 901 Mountain Ave. in Springfield, leased 1,848 square feet to Summit Medical Group and 3,500 square feet to Vayu, a health care technology and products services company, according to the announcement.

Larken purchased the 41,181-square-foot mixed-use property in 2010, the announcement said, and since has overhauled the façade of the building and refurbished the common areas and vacant units.

“We’ve had a very high leasing percentage at Echo Executive Plaza since we bought the property because of its great location at Route 22,” said Victor Kelly, executive vice president for Larken’s commercial division.  “However, our strategy to make tenant improvements to make the property more comfortable or modern for our tenants and their customers, the money we spend always comes back to us in repeat, long-term business.”
