Making Visitable Changes Might Be Necessary
Many homes aren't initially designed with Visitability features in mind. Sometimes, when the homeowner requires it, ramps must be added to provide access.
This home has a concrete, switchback ramp with handrails to achieve the necessary zero-step requirement without being so steep as to be unusable.
A first floor bathroom with no threshold allows the owner and visitors alike to have access to the facilities regardless of mobility level.
