We meet former participants who are now finally finished with their projects. Or are they? And how are they, now that the house project is finished? Is everything working as it should in Erik and Laura's round straw bale house in Umeå? How many tomatoes is there room for in Johan and Sylvia's nature house in Lerum? And have Mea and Bruno in Fyledalen finally moved into their small little house on the farm?

Kim and Erik dream big. Together with Kim's sister and her husband and three children they have bought an old family farm in Dalarna consisting of 13 buildings in various sizes. Of all the houses, Kim and Erik decide to make the stable into their home.

Vici and Peter long for the simple life. They are building their allotment house with a walking distance between their apartment and the preschool at Hisingen. They decide to do the exact opposite of what Gert says you shouldn't do with the construction of the house. Because you have to challenge yourself. And who cheap can you actually build using reclaimed building material?

When they move in, at least 40 people will be living together in Malmö. But before that can happen they have to renovate what once was a mental hospital into a collective house. The idea is that it will be a home where the community spirit is central, but where the individual also can take place. There are plenty of ideas, but how will it turn out and will they be able to agree when nearly 3000 sqm are under construction?

When a 103-year-old relative decides to give away their inheritance in advance, Simon and Therése suddenly have the opportunity to build their dream house in Trångsund outside Stockholm. It is a hilly and steep plot but instead of blasting away the bedrock they decide to build with nature and let the mountain dictate what the house will look like.

Anna and Joakim gladly does the opposite. When they started to look for a house on Tjörn eight years ago they first and foremost looked for a garden as they are both gardeners. Now that both the garden and the family have outgrown their small cottage on the lot they want to build a large and nice house, but it has to be completely adapted to the garden. How do you do that?
