On Why I Do Not Grow, But I Mortgage

Abstract

A progressive growth house is a basic, incomplete and habitable unit based on the principles of adaptive development, which, due to its size, also becomes available in the current market and from the beginning of the project is conceived to have its surface increased at some point, making it possible to save costs and materials. If in other countries it has been proven that this is a good way to provide flexible and adaptable low cost housing, why haven’t more of these houses been built in Spain, since they do not compromise the future of its inhabitants with high mortgages and they allow them to progressively improve and enlarge their homes? Causes such as the high cost of legalization of each future extension compared to the construction of a single phase, the indecision produced by the fact that any modifications made must be approved by a community of neighbors or unawareness of the possibilities provided by growth systems when used in consolidated cities have led to this type of housing not being used more, despite being an extraordinary way to solve the housing shortage problem.
