During the Victorian period there were three reasons for changing the physical structure of country houses: altering, enlarging, and modernizing. More often than not these changes tended to be cautious and conservative. Alterations reflected changes in taste, a need for restoration or maintenance, or a desire for improvements. Examples illustrate the changes that were wrought. After 1940, there was a mood to de-Victorianize. The Society for the Protection of Ancient Buildings (SPAB) has now taken the position that to restore a home to some so-called original model is an act of forgery.
