| We are renovating and have moved some doorways around. One new doorway opens up in the very center of the oldest part of the house. The settling of the house (red clay region) has caused the center (beam?) to rise up. I have noticed the elevation change for some time, but it never struck me as a problem until we had this doorway knocked out.
One day when I was away, GC was filling in the gap in the threshold on the floor in this doorway. I arrived home before he got too far. He was planning to fill it in and cover them with a raised strip of wood. We have had these strips elsewhere and find them problematic, so I asked if he could find one strip of nice wood to put in there instead. He said he would try, and it would save him from having to do what he was doing.
He didn't mention (can't imagine that he didn't notice) the difference between the two floors from one space to the next. The more even floor is newer construction.
I don't think I want the old floor sanded down enough to match the newer part. But I also don't want a raised strip of wood to trip over. It is our new path from garage to kitchen and will be frequently traveled by all.
Any other suggestions for how to fix it and make it look decent?
Foreground is newer construction; elevated floor is older

Thank you for any help you can give! |
