In addition SE will design a “honeycomb footing” this just means there are footings running the width and length of the slab criss crossing perpendicular to each other the entire area of the foundation.

I used the 12x24 click vinyl planks so the only seam was perpendicular to the tread.

This wall runs perpendicular to the ceiling joists, so it would typically be a load bearing wall.

Looking at some type of click lock vinyl flooring but I need a type of stone pattern in the entryway and kitchen as these areas are perpendicular and wood plank would look weird.

Grab a 8ft level and check the ceiling planarity perpendicular to the removed wall.

I think we'll keep the desk area as is because we are planning on adding a door on the perpendicular wall out to the patio as we're seriously considering adding a saltwater hot tub.

The builder showed me the framing company was just “following the software” and had designed a truss system that met in the center of the unit from the front/back and then perpendicular trusses cantilevered at the open staircase.

If it ran perpendicular to how you walk into the bathroom I could just pull it from that wall and it would be easer.  

.* Tile - If you can use a natural stone for the shower/bath surround, you may be able to save money and just grind/sand the end down to bullnose or rounded, instead of having to buy special bullnose pieces or down angles (2 bullnosed perpendicular sides), which are more expensive then the field tile.

Assuming the lines are perpendicular from the street I should be ok.
