Can we shiplap over a 32m tall, 4m wide wall without breaking the bank?

Hey there,

We’ve got this huge empty wall that’s about 3.2 meters tall and 4 meters wide. We’re thinking of turning it into a shiplap wall, but we’re trying to keep costs down.

Do you think we can just add shiplap on top of what’s already there? Any tips on how to go about this?

Thanks so much!
