Whilst our master bedroom is upstairs, we have (as closely as possible) replicated this downstairs so that we can switch to ground floor living if/when it becomes necessary. We also have gone for wide doors everywhere, no thresholds internally (Karndean flooring throughout), flush thresholds on all external doors (including onto patio/deck), lowered kitchen worktops on handleless cupboards, no wall cupboards, eye-level (actually slightly lower than normal) ovens with slide and hide doors, a four burner hob with all four arranged in a single row so no need to reach across to back burners, midi height fridge and freezers (no point having fulĺ height if you can't reach the top shelves), inward opening windows with the handles positioned low on the frame, low tray walk in showers with low level shower controls, simple push button privacy locks on the bathroom doors and a fully open plan kitchen/dining/living space.
