I'm going to change my small formal dining room into my new home office - we have a large kitchen eating area that we use all the time, and have lived in this house for 7 years and have used the dining room to eat like 5 times ever. So it's essentially a mostly walled off room, there is an opening that looks like it was designed for french doors as an option - just about seven feet wide and eight feet tall. Then there is a small passage way from the dining room to the kitchen that is right at 36-inches wide and one side has nothing in the wall, no outlets or switches. What's it going to cost? I'm looking at the pre-hung french door at 36"x2 would mean there would have to be 6-inches of wall built on either side (or 12-inches on just one side) ... pricing out Lowes / Home Depot stocked models about $350. The pocket door total looks like about $125 for the door and the complete framed pocket door kit they sell. I know there's labor, paint, nails, time ... What's some rough estimates for what it would cost? Mind you, I don't want someone who doesn't know what they're doing coming out here to do this ... and I don't want the best either. Update: just adding in better photos. Going to use one of these pre-hung stock french doors and I may have to hunt around to find the 36-inch french doors that match close to the rest of the house. Here's the unused dining room that will be my new office, but with the doors on it, a future owner could use this as a formal dining room again. 36" opening that goes into the kitchen.
