Re: laying a floating wood floor
It depends on the layout of where the flooring is going to be laid, sight lines, and what you're trying to achieve.
Typically you want to run the flooring the length of a hallway or room, not across it, which may necessitate a direction change when entering a room. Depending on the width and type of flooring used, you may start in the middle of the space and work outward OR you may start against a wall and work your way across.
I know this doesn't really clarify your questions, but it's how the pro's decide how to lay and where to start on a project. I can also tell you that some products are made to be assembled in a certain direction, Pergo 'click' flooring for instance, really needs to be started against a wall and worked across the floor because it is easier to assemble working tongue to groove rather than groove to tongue as you interlock them.
