We didn't specifically go looking for a Baufritz, so it wasn't a deliberate choice as such. We saw the house advertised by an estate agent, it's in the area we want to be in, and within our budget, so we bought it. ?
The fact that it is flooded with natural light, is open plan, is well built, and has eco credentials (air source heat pump, solar panels, passivhaus certification) and is of a design and style that we like is of course all highly beneficial.
However, we weren't previously familiar with either passive houses or this type of modular construction, so we'll undoubtedly be asking some (dumb) questions shortly... ?
