§ Mr. W. Hamilton
asked the Secretary of State for Scotland what is his estimate of the number of houses over 100 years old and over 50 years old, respectively; and what is the current annual rate of replacement of the older houses.
§ Mr. Noble
No estimate is available of the number of houses over 100 years old, but about 340,000 houses are estimated to have been built before 1875. The number of houses over 50 years old is estimated at about 770,000. The annual replacement rate is about 12,000.
