Hand build wood transition strip two different height floors
Yes, you can make a transition strip from wood. Without a more detailed picture and look into the area affected, it's hard to offer much more of an idea - cut wood to fit hole, mark floor level on each side, cut/plane/trim/rasp/beltsand to the marked line on each side, stain, fail to match the flooring color and either &quot;not quite match&quot; or go for &quot;deliberately accentuate it since it won't match anyway.&quot; Not matching may reduce the tripping hazard (But I can't tell how much elevation difference from that picture, either)
Depending on the flooring material, you might be able to attach a chunk to a wood strip cut lower by the thickness of the floor for a better match.
