The owner of Lower Allen Township-based Brickbox Enterprises Ltd. last week closed on the purchase of the Barto Building at 420 N. Third St. and a second office building at 319 Market St., according to Dauphin County property records.

The buildings, both owned by the Pennsylvania AFL-CIO, were acquired for about $1.3 million in total, county records show.

One of the limited partnerships Deitchman used to purchase the buildings — Lux I LP — also took out an open-ended mortgage for nearly $2.9 million, according to the county.

The Barto Building is slated for residential reuse. The plan is to convert the office building, which is across from the state Capitol complex, into 50 condominiums.

Deitchman was not immediately available for comment on plans for the Market Street property.

He previously purchased buildings at 301 and 335 Market St. Both have been converted to student housing for Harrisburg University of Science and Technology.

The university has said plans are in the works for a third building in 2014. A location has not been announced. University spokesman Steven Infanti said there have been discussions with Deitchman over new housing.

The developer also is working with Harrisburg-based GreenWorks Development on the redevelopment of the historic Furlow Building in Midtown Harrisburg for market-rate apartments and first-floor retail space.

That project, known as the Coba Apartments, is nearly complete, said Matt Tunnell, senior vice president at GreenWorks.

Deitchman also was behind the Riverview Manor housing project on North Front Street. In June, he purchased the Scottsdale Plaza shopping center on Paxton Street in Swatara Township.
