In less than a year from the initial inquiry, moved in? Probably: Nope. With prefab house providers, the time saved on shell construction is spent on the waiting list (interior finishing then doesn't necessarily go faster than with a solid house). If you had a plot of land, maybe (candidate: Viebrockhaus, if they build in your area). Does Deutsche Reihenhaus currently have a project for sale in the area? Or other developer projects, of course.
