Hi. We're working on a flooring plan for the new house we're building. The layout is in the attached image.

The red areas are for laminate / LVP (haven't fully decided which yet). Green is carpet. Light blue is tile. The bathrooms and kitchen will likely have sheet vinyl.

My question is how to transition "around the corner" from the section labeled "Dining" to the hallway going "up and down"? It is my understanding that laminate / LVP should be laid parallel to the longest wall (thus left to right in the image). However, in the hallway, it should run the length of the hall (thus up and down in the image).

1. Would we cut the pieces to end at 45's along the green/red intersection?
2. Would it be ok to just right left to right shorter planks in the hall to maintain "flow"?
3. Is the long run from the far right mudroom to the green/red intersection too long w/o a transition strip?

We're thinking about DIYing this, BTW. Thanks for your consideration.
