Hi there,

Your vision for a timber finish on the vaulted ceiling sounds beautiful! Birch Ply is a great choice for a pale honey tone, and it can create a warm yet modern aesthetic. Regarding the thickness, 18mm is ideal for stability and longevity, but thinner options (such as 12-15mm) might work if supported properly. It’s worth discussing this with your builder to ensure it meets structural and safety standards.

If you’re considering a colour-washed timber look, it’s a great way to add a soft, contemporary touch while still showing the wood grain. Whitewashed or lightly stained panels can also help brighten the space.

Both options can look stunning—it ultimately depends on whether you want a natural, warm vibe or a lighter, more Scandinavian aesthetic. Let us know what you decide—we’d love to see the results!

And please feel free to ask any other questions!

Best wishes,
