The multi-level apartment building is located in Philadelphia's Fishtown neighbourhood, a transitioning area that has been attracting creative types and urban professionals.

Local firm ISA, or Interface Studio Architects, designed the Signal House to respond to its context, described as "a boisterous mix of elevated rail infrastructure, industrial buildings, late-night bars and restaurants, and busy arterial streets".

Built to accommodate singles, couples or families, the 3,500-square-foot (325 square metre) building occupies a site that typically would hold a single-family rowhouse. The site is 32 feet deep (9.8 metres) and just under 26 feet wide (eight metres).
