I've done some more research for you guys.

I spoke to a guy at "Arkitekthus" to try to get some info on how/where their houses are produced. It turned out the level of prefabrication is not particularly high. Walls are prefabricated in a factory (2,5 h from Stockholm) and all the rest is done on site. The thing about Arkitekthus is that they offer a nice collection of "monteringsfärdiga hus", a common genre in Sweden, but in this case with unusually high ambitions in terms of design. There are other things I think would be more interesting for you to look at, in case you don't have a lot of time and want to a broader scan of the market.

I talked to one of the young architects I mentioned to you before. His name is Anders Holmberg (www.andersholmberg.se) and he's currently working with a small manufacturer (1 h from Stockholm) on a collection of affordable houses using a supposedly very ambitious prefabrication method ("A new affordable typehouse collection for Björklidenhus" on his website). Some of these houses, and some zero energy ones where he's using a different technique, are about to be assembled just outside of Stockholm around the time you get here, in case that is February. He would be happy to support you with a guided tour, images and other stuff you need. (Anders on American prefab: "They need help over there!") :-)

Another manufacturer at the forefront of offsite construction in Sweden is "Moelven". They claim to be ahead of the big companies in this sense, and they will probably have a project at various stages of completion in their factory around the time you get here. The factory is just outside a small town where the train stops going from Malmö to Stockholm, and they will probably also do onsite work on another project in Stockholm around the same time...

How does this sound?
