Maguire Hayden Real Estate Co. of Conshohocken has purchased West Chester Office Plaza, a five-building business park on 8.3 acres near downtown West Chester in Chester County.

Maguire Hayden acquired the properties, encompassing 116,621 square feet of space at East Market Street and Westtown Road, for $12.5 million, according to an email Monday from CBRE, which represented seller High Associates Ltd. of Lancaster in the transaction.

The office buildings, completed between 1964 and 1976, are 90 percent leased to tenants including American Precision Industries Inc., ESCFederal Inc. and Women's Health Care Group of PA, CBRE said.

CBRE brokers Stephen Marzullo and Adam Silverman marketed the property and negotiated its sale for High Associates.
