Interesting, I think production by IKEA is the only feasible direction for producing and selling this as people's homes are too varied for any single configuration to work.
It looks very nice. I might be willing to spend ~1K on this but only if it exactly fits my needs, and even within just my current residence the window sizes and ceiling heights are dramatically different from room to room.
Speaking of which they should offer an ORI configuration where the back office wall is open to an exterior window so that it is more suitable for a corner room with two exterior walls.
From a cursory look, this is more a 10k than 1k piece of furniture. The hinged cabinets alone would cost significantly more than 1000$ (the materials aren't stellar, however, especially the laminate wood, ugh).
