Our flooring is not even close to as nice as the pics Damian posted.
I guess you'd call it "poor-man's pine" flooring? It is 150 y/o, and really could use another coat of urethane pretty bad. In the first pic, you can see where I removed a large butler's pantry cabinet and had to add flooring. Luckily, I know a custom wood flooring/trim cutter who was able to match the size and grain pattern of the old floor. It was
not cheap. It hasnt been finished yet.
The wife and I discussed installing laminate flooring over it when we finally remodel the kitchen, but it just wouldnt look right to me. I like the imperfections in it...its the "character" of the floor.
We have the same type of flooring thoughout the first floor of the house, but the rest is covered with carpet. The upstairs wood "flooring" is really just the subfloor. Good for carpet base but not much else.
