We decided to open up only the future front room's ceiling.
There will be a lot of work involved in re-routing the pipes and electricity. But it will be worth it. My builder is a woodworker from Poland and loves wood as much as I do. He was very excited as well! He proposes to simply oil the ceiling; no sanding or repairing. And also, no boarding between the beams.
The new oak floor has been delivered too and will replace the laminate flooring.
