The single-family home remains the most popular form of private housing. It is still relatively young, having emerged as a workers' house in the 19th century, and reached its first peak in the 1970s. The construction industry, landowners, and municipalities initially benefited from the private building boom; however, spatial planning regulations were circumvented. Today, we see the consequences: the agglomerations are sprawled with low-density single-family home developments. The costs of building and maintaining infrastructure burden the municipalities. Additionally, many homeowners from the "baby boomer" generation are now elderly and no longer able to manage their homes and gardens, leading to vacancies as they move away. How can single-family home neighborhoods be made fit for sustainable future use? How can they remain attractive to their residents and young families? This publication addresses these questions.
