Reading or high intensity lights may be necessary for reading, sewing and hobby work. Good lighting decreases the chance of falls. Living and bedroom windows that face south provide maximum winter sunshine. It should be possible to clean windows from the inside. At least one window in each room should be easily opened and large enough for easy escape in case of fire.
Elderly people are sometimes unable to detect escaping gas.
Many retirement housing options provide utilities as part of monthly rent. Leave straight clear paths through rooms. Arrange furniture away from drafty doors and windows. Fire escape routes should be identified and care should be taken not to block these with large pieces of furniture. Install a bedside phone for emergency calling and another in the living area so that you won't have to run from room to room to answer.
