ok so this is my dining room floor. as you can see in the corner im pulling up the subflooring. The original plan was to just laminte wood floor over it. the sub flooring was uneven so i took a peek under it and saw that it was actual wood (see the dark color) so we decided to start pulling it up and use original and save our money for other projects. as you can also see that it looks like there was a wall that they took out, or there they widened the house. but the wood is different on the other side (wider and going different direction). so we are really at a loss on what to do now. The lighter side (with the bigger planks) is also on the side with the stairs and window. It is also noticable that cold air from under the house is coming up though there. I can get more pics if that helps
