With the recent trend toward larger families, 

 the increase of owner-occupied housing, and the 

 enthusiasm for do-it-yourself projects, there is 

 reason to expect that residential alterations and 

 additions will tend to keep pace with the increase 

 in the Nation's stock of housing. For a while, at 

 least, the amount of such work being done may 

 increase even faster than the stock of housing. 

 Complaints are often heard that much of the 

 housing built during the past 20 years does not 

 provide enough space and privacy for families 

 who are now occupying it. Alterations and 

 additions help partially to solve this problem.

> Derived from Department of Commerce estimates of 

 annual expenditure by use of E. H. Boeckh and Associates' 

 construction-cost index for new residences. 



2 Not available. 



Source: U. S. Department of Commerce and U. S. 

 Department of Labor. Construction Volume and Costs 

 1915-54, Statistical Supplement to Construction Review. 

 Washington, D. C. 1956; Construction Review, January 

 1956. 



Department of Labor estimates, based on 

 building-permit data, of the annual expenditures '°* 

 for residential alterations and additions show that 

 the general trend in volume of this kind of con- 

 struction has been upward (table 224). The trend 

 has been roughly parallel to the increase in number 

 of households,^"* as might be expected (fig. 116). 



During the forthcoming 45 years, it appears 

 reasonable to expect that volume of alterations 



"" Converted to 1953 prices of new residential construc- 

 tion. While the prices of alterations and repairs are 

 probably not exactly the same as those for new con- 

 struction, no separate index of alterations-and-additions 

 prices is available. The index for new-construction prices 

 appears to be a more reliable deflator than any other 

 presently available. 



■"5 A comparison of the volume of alterations and 

 additions and the growth in the Nation's stock of dwelling 

 units would be even more appropriate. Such a com- 

 parison, however, cannot be made on a long-term basis 

 because there was no Census of Housing prior to 1940. 

 Reasonably reliable estimates of the number of households 

 extend back to 1915 and bevond.
