I am remodeling a cottage. It was originally a cape. At some point they added dormers to the front and back to create a second floor. The flat part of the ceiling is low. There is a hallway across the center of the house. The bedrooms are on either side of the hallway. The top of the doors are framed with 3 2x3's stacked to work as the door frame and header. Above the doors are 2x6's that act as the ceiling joists and collar ties ( perpendicular to the doors). With the 3 2x3's I have to cut down 78" doors to fit. Can I cut out one of the 2x3's so that I can use a 78" door? I should have just enough room for trim without hitting the ceiling. I was told by a builder that I would be fine with two because there were only holding the ceiling and there the other side of the hall is also supporting the ceiling.

Hello, I just purchased a house and am slowly fixing things up. In the back yard there is a shed that currently has a dirt floor that i want to make into a shop for myself. I plan on building a wood frame floor with pressure treated lumber and using concrete deck blocks. I've been doing some research will be adding moisture barrier and digging out some of the dirt to have the floor be at least a few inches off the ground. I also want to add some plywood to cover up the beams in the walls. so my questions are, do i build the frame outside the shed and carry it inside, or do i build it where it will lay? should i put the plywood boards up for the walls before the floor goes in and fit the floor between the walls or put the floor flush with the beams and then cut the boards to fit on top of the floor? should i use nails or screws for the floor framing work, which will be more durable and hold better? I was leaning towards screws but after watching a video or two everyone is using nails for framing, not sure if thats because its quicker or more durable... I'm not sure if any of this stuff even matters, but I just want to make sure I do this right the first time. I'm not a beginner when it comes to DIY stuff but I have never built a floor or done any framing. Thanks for any and all help/info!
