About This Project

This Northern Liberties, Pennsylvania development was built on the grounds of an old horse stable, hence the name – The Stables. Net Zero Energy and Passive House Certified, it features INTUS Eforte steel reinforced triple pane polymer windows. These homes were prefabricated and designed and built with efficiency in mind, reducing energy consumption by up to 90%. This is largely possible to the building envelope and INTUS’ triple-pane fenestrations. 

“The houses are going to be completely energy sufficient by themselves, occupants will be responsible for energy use–what’s called net-zero energy possible,” says Timothy McDonald, a principal at Onion Flats. 

There are three groups of townhomes, with 9 in each, for a total of 27 energy efficient, modern, daylight filling homes just steps away from an array of retail, the SEPTA buses, and highways.
