36th and Lancaster.

The Philadelphia Historical Commission will consider proposals on Friday to add the Second Empire style twins at 43rd and Osage and the south side of the 3600 block of Lancaster Avenue, both eyed by developers, to the Register of Historic Places.

The commission’s Committee on Historic Designation recommended both properties last month and now they go before the full commission. Placement on the Historic Register stipulates that the commission “must review all proposals that require a building permit and/or that would alter the appearance of the historic resource prior to the commencement of work,” according to the commission website.

Here’s more background on both properties.

The meeting begins at 9 a.m. at 1515 Arch Street, room 18-029. Click here for the full agenda.
