46 6 DESIGN GUIDELINES FOR THE ELDERY AND ELDERLY WITH FRAILTY

47 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 turning and manipulating taps, switches, door handles and the like.  May have difficulties in pushing open heavy doors.

48 Enhanced Designs Barrier free access without steps Slower speed of escalators Luminous contrast between wall and floor Resting place along long corridor Different colour floors and zonings to improve way finding Double switches and low level cupboards Timber or plastic-coated hand rails Bathroom doors openable on both sides Sound-absorbing materials and non-glare floor finishes
