Picture of bifold barn door (as limited pictures were allowed).

I think it would help others to visualize your space (and better answer your question) if you posted an overhead, to-scale plan with all measurements and adjacent spaces marked. Example below, from the Read Me First thread.

PS - Cute dog!

If I'm referring to the wrong place you want to put a door, then disregard my comments below. I read your post to mean you want to put a door between the kitchen and the little landing area that will have three doors.

Why do you even need or want a door to that little space where teh three doors will be? It's a landing space of sorts, so what? Why does it need to be behind a door? You really want to enter through TWO doors to get from the mudroom into the kitchen? You're creating a problem when there isn't one. I would just leave that open and just have the door cut in on the wall you indicated. Upgrade to nicer-looking interior doors than the one you have now, something that aligns with the modern kitchen you're building.

If you're going to do it anyway, NO to that barn door bi-fold. I have a barn door and staunchly defend them when used in the right circumstances, but not this bi-fold thing. It doesn't accomplish anything a regular bi-fold won't, but even that will be a PITA if that is your main point of entry. Meaning NO to a bi-fold at your entry point.

I'd start by thinking about what doors can be moved out of that hallway. For example, could you put a door to the basement at the bottom of the stairs? Could you put a pull-down door at the top of the basement stairs and leave the door to the mudroom open? Could you put a door to your little 3-door landing area, (ie from where it says problem light switch to modern kitchen.

Bifold doors tend to need a track or groove at the bottom to stay in place. You also need room to stack the folds when it's open. My parents had an attractive, wood folding door.

Think about opening a sliding or bi-fold door with your arms full, taking a load to the mudroom or the garage. Not fun.

Do you have to install a door from the kitchen to the landing? If so, you have a few options.

The light switch in the kitchen can be moved to allow space for a door frame. The one leading do the garage can actually be in the door jamb, if allowed by code. Maybe use a wider jamb to accomodate the switch.

If you must keep the current switch configuration and install a door in the kitchen, consider a pair of full height double swinging doors without a door frame. You will have to make sure the leaf on the garage door side misses that door handle, You could even change the swing of the garage door so the handle is on the other side.

In my opinion, doors are a pain in the neck unless they are needed for privacy or safety. In that small area, I think you will have real problems with any actual door other than the one already there that goes to the garage/basement which is needed by you husband. I would cut a doorway to the mudroom, as you plan, but just leave it at that -- an opening that is finished either just with drywall or a wood frame, whatever matches the style of the rest of the kitchen and house. The same with the doorway from the kitchen into the landing -- just leave it as a framed and open doorway. As for the proposed door at the right going down the stairs to the basement -- the main concern would be safety. You don't want someone accidentally taking a mis-step on that small landing and falling down the stairs. I can't see how far the landing extends to the right before the stairs begin so it's a little hard to know where to put a barrier or what type. If the stairs begin near to where that curtain is, then I think your only choice is to put a door, and I would use eith a pocket door that slides into the wall of the mudroom or a plain swinging door. I don't know how often you use those stairs to the basement, but if it is only occasionally, then is it possible to close off that opening completely and use the garage stairs from the "service door" as the sole basement access?

How about a pocket door?

Here is the birdseye view for referrence. Going to read the comments now! Thanks!

Thanks all for your comments.

Reasoning for the door:

- somewhat of a noise barrier between the basement and the rest of the house. We have two pre-teens that use the downstairs as hang out space.

- safety to block the stairs from the mainfloor living area. I have young nieces and nephews that I'd like to be able to contain on the main floor (mind you a sliding door isn't fooling any sneaky toddler).

- noise barrier from laundry

- want to be able to block off the site line to the mudroom (aka kid drop zone)

We expect the door(s) to be open the majority of the time with it being closed when we have company over, the kids have friends over, or the washing machine and dryer are rattling away.

Unfortunately the wall behind the over is filled with electrical, plumbing, etc, and the wall the other way is an "exterior" wall (against the garage).

The landing is very small with the first step at the curtain, and the bottom of the stairs has the stairs extend beyond the wall in the basement so a door can't go at the bottom.

I'm annoyed (at myself) this was missed. I had it drawn into our plans but it was obviously missed by the person framing and the electrican...now we're 2 days away from drywall and I'm trying to bandaid it together.

The only thing worse than a barn door in any situation is a bifold barn door. That will block about as much noise as a screen door. I do not have a better solution but a blanket blocked to the wall would be my choice before a barn doors or a bifolding barn door.

^^ Gee, millworkman -- tell us how you really feel. LOL!

I still don't understand why you need a door from the kitchen to the landing -- just put good-looking doors on all three of those other places and be done with it, leave the doorway between kitchn and landing door-free.

agree barn doors dont block noise. get a toddler gate for the kids.
