Open plan designs often include shorter hallways, which is preferable for ease of movement. In new or existing hallways, a minimum width of at least 42 inches provides ample room for all family members. Anyone using medical equipment will appreciate the extra space. Wider hallways also make moving large furniture and appliances easier.
Altering hallway width may involve moving or eliminating structural walls. This usually will require the expertise of a remodeler.
Make sure that doorways are also at least 32 inches wide (34 inches preferred)
