6sqft often covers space-saving design and multi-functional furniture, but it’s not everyday that we get to share interior design and architecture that has the potential to significantly impact someone’s quality of life. However, the renovation of this 1,500-square-foot Harlem apartment, led by the architecture firm Ten to One, is a great example of this type of universal design. The apartment was designed to provide distinct access for a family member who is in a wheelchair. The redesign features clever architectural detailing that gives each room the ability to blend together or be separate and surfaces that can act as figures or enclosures. It also introduced a system of walls and ceilings that cut through the existing structure to expose new depths.
