Recommendations 19 to 24 of the International Plan of Action on Ageing emphasize that housing for the elderly must be viewed as more than mere shelter and that, in addition to the physical, it has psychological and social significance which should be taken into account. Accordingly, national policies should help elderly persons to continue to live in their own homes as long as possible, through the restoration, development and improvement of homes and their adaptation to the ability of those persons to gain access to and use them (recommendation 19). Recommendation 20 stresses the need for urban rebuilding and development planning and law to pay special attention to the problems of the ageing, assisting in securing their social integration. Recommendation 22 draws attention to the need to take account of the functional capacity of the elderly in order to provide them with a better living environment and facilitate mobility and communication through the provision of adequate means of transport.
