Barn Again. Caught in a Cliché

Well it's a start. I've begun to demolish the first floor of the larger barn. I'm taking up the chestnut floorboards, some of which are over 60 cms (24'') wide. The plan is to reuse some of them for internal doors - à la mode Provencale (horizontal boarding). The supporting beams, also of chestnut will be reused as ceiling joist in the first floor bedrooms.
