I have learnt that even though the ceiling looks like it's exposed but it's not. There are electrical, vents and things under that ceiling. Then they apply faux beams on top of that. That's the reason why this costs more than regular ceiling. Don't like the sound of that!
This is the look of the ceiling that I'm going for in my master bedroom. Except my roof is lower pitch.
This is just a plain ceiling no beam. This is my backup plan if I ran out of money to buy beams:)
