Blandair is an eighteenth century farm located on approximately 300 acres in the heart of Columbia. The farm is bisected by Route 175.

The main house is a fine brick mansion with many unique architectural characteristics including decorative brickwork, fine marble fireplaces, and decorative mouldings.

In addition to the main house, Blandair has many fine outbuildings, including two barns, a stone home that may predate the main house, a log cabin, and a stone dairy.

In 1987, Celia M. Holland called Blandair "one of the county's most handsome brick houses" in her book, Old Homes and Families of Howard County, Maryland. Holland also quotes 1798 tax records as reporting:

"One brick dwelling 46 x 36 two stories, one olde stone house, one olde stone kitchen, one brick smokehouse, one brick dairy."

The buildings continue to deteriorate and are in critical need of basic repairs, stabilization and restoration.

A select committee is working with the Department of Recreation and Parks to develop recommendations for the use of the property, the main house and the outbuildings. PHC supports the preservation of these buildings as they offer a rare opportunity to preserve a specific time in the agricultural history and heritage of Howard County.
