Cunningham Piano Company sells historic factory building in Germantown section of Philadelphia

The historic Cunningham Piano Company building in the Germantown section of Philadelphia will soon close its doors before the nearly 135-year-old business relocates its functions to King of Prussia.

The factory on Coulter Street just off Germantown Avenue has housed Cunningham's restoration operations for generations, the company said. The move to King of Prussia will bring all the work done at the Germantown factory into one space, accompanied by the existing KOP showroom.

When it comes to pianos and the Cunningham name, this place is about as Philadelphia as the Liberty Bell.

Cunningham has restored pianos of all varieties, makes and models since 1891. There are the old dust-collectors and throwbacks to another century. Some even survived fires.

The company, its dusty factory smelling of strong varnish, is ready to part with pretty much everything here, and all of these instruments need new homes.

Before moving, Cunningham is inviting the public inside the historic building one last time — and everything in the factory will be put up for sale, from pianos new and old to materials used to restore them and even pieces of the building itself. These tours will take place over the next three weeks.

While they're closing a storied musical chapter in Germantown, the company is consolidating, making its existing King of Prussia location a new headquarters.

Things look optimistic, and company leaders are bullish about piano sales.

Cunningham says it accounts for 50% of sales in the Delaware Valley piano industry and market.

The Coulter Street building is more than a century old and was initially built as a stable before it was a warehouse for caskets.

Cunningham has additional retail locations in Cherry Hill, New Jersey, and Delmar, Delaware.
