Thanks, I think it is "Walled In (2009)"! The story is not quite what I remember, but the building shown in the trailer looks right.

I only remember a few details about this movie (perhaps from the late 90s, early 2000s, could be wrong) - a couple is moving into a brutalist concrete building, the architect/builder had gone missing,...

I think it starts with one brother putting a body he found in his truck and then he is stopped by the police. The other brother is dominate. They have a couple tied up in the building they use for butchering...
