6DESIGN GUIDELINES FOR THE ELDERY

AND ELDERLY WITH FRAILTY

Design Considerations Elderly persons

May be unstable in their gait and unable to recognise changes in level of floor surfaces.

May be unable to see clearly and may have problems in accommodating dramatic changes of lighting levels.

Would have decreased stamina. May have difficulties in way finding. May fall due to bending, stooping and stretching. May be weak in gripping, and may have difficulties in t

urning and manipulating taps, switches, door handles and the like.

May have difficulties in pushing open heavy doors.

Enhanced DesignsBarrier free access without stepsSlower speed of escalatorsLuminous contrast between wall and floorResting place along long corridorDifferent colour floors and zonings to improve way findingDouble switches and low level cupboardsTimber or plastic-coated hand railsBathroom doors openable on both sidesSound-absorbing materials and non-glare floor finishes
