We have a loft area that has a built in office which is currently open to the hallway upstairs. We are looking to enclose this with something like french doors (or sliding doors) so we can close this off if we need to block out noise and create some privacy when we work from home (baby is at home with nanny). It is currently completely open and has a rather large arched opening. Any cost-effective ideas? So far, I'm thinking it probably would be best to un-arch and put in some support/drywall for a standard glass french door and install. But, I'm very open to ideas as we are trying to figure out if it's even worth it or not.
