IMO MCM should not have french doors. My choice would be to replace those with new better made doors . But I need to see your issues with furniture the other choice of the fixed and slider would be my next best . Are you keeping the knotty pine ? I had tons in my MCM ranch but I hate it so it is all gone I like the look of a more clean lined home .

Patricia, thanks for your comments. I agree about French doors. It would only be a last resort or temporary fix if we did that. We we’re thinking new 10’ sliders might be pretty pricey. I like also like the idea of having space on either side of the door for furniture and the walkway in the middle of the wall rather than on side. Not sure of all the layout yet. Most of the house doesn’t have this knotty pine. I don’t mind a little of it but we’re going to wait and see before getting rid of it. The kitchen is the other area that has it and that is going away or maybe paint at first until the budget allows a total reno of the kitchen. Red will also be going away. 😊

Option 2. Check with local city codes first to see if the big openings are grandfathered in or need to be made smaller for earthquake safety or energy efficiency.

Have you considered walk out bi-fold doors as an option? I would avoid the 10’ slider.

I was going to inquire about what jrb mentioned. I love a large span and 10’ height is unique. I have 10’ bifolds that open out. If you did that you can open the whole span and furniture would not be impacted. Only drawback is it might be a bit of a modern look but it would be nice to open the whole room to the outside.

Another option

I love the bifold option but we live in FL and between heat, humidity and mosquitoes I’m afraid they wouldn’t be open often enough to justify the budget.

All things considered, I think option 2 is the best. It offers the most benefits in the pro/plus column.

Good eye re. the floor vent needing to be moved for option

Ooops, was addressing that to Kim and accidentally tapped post. One thing to consider for option 3 is that because the doorway is on one end, the drapery stack has to be all on one side, thus making it double the width and covering even more of the view all on one side. It probably would work best to be sure to allow room for wall mounted blinds to be installed at the ceiling above the doors. That way they can stack completely out of the way of the doors.

'I had tons in my MCM ranch but I hate it''

I don't mind knotty pine in small doses for retro flavor. I hate skinny white painted trim though.... esp in houses of this era. I would paint it same color as wall, or at least something less contrasty maybe some mid tone gray or beige to better fit in MCM esthetic.

Yes, good catch on the floor vent. I wouldn‘t move it because we are keeping the floors and moving the vent would mean patching the floor. Thanks for the input. Great things to consider. I agree with you Debbie, I would not do white trim unless I do white walls. I’ve used white walls with light griege trim in another home and really liked it. Still reading and looking at lots of MCM houses for ideas on paint colors.
