You have used a hypothetical where a homeowner, of a two bedroom house, converts a garage into a third bedroom and have offered it as an example of an improvement that would increase the value of the home.
Actually, in some neighborhoods that "improvement" would have the effect of decreasing the value of the home. It is certainly an improvement but it is an example of one that could have the effect of neither increasing nor maintaining value.
