After clean up I think I'm ready to start the project and here is the situtation..... (pics below)

Laying down bamboo planks on concrete slab (second floor). I've grinded down any high spots on the slabs so that it is flat. The wood will go on the entire upstairs. So I wanted to run it down the hall horizontally (longest sight line)

I have a bullnose and was going to start my line based on that and run the planks horizontally across the hallway, but if I do so it won't be square with any wall (see second pic). In addition it won't be straight down the hall and into the room, i.e. it will run at a slight angle not parallel to any wall

So do I choose another laydown - diagonal and not down the hallway or can I make the line straight (parallel to the walls) and into the room and then make a correction at the bullnose when I get there?

Hopefully with the pictures what I'm asking makes sense, if not I will clarify. Suggestions greatly appreciated.

The pics definitely help explain what you're trying to do. I'm sure there is a way this can be corrected, and if so, someone here I'm sure can help you. What I do know is that if you were to run it at an angle, that would look really nice. That's what I would most likely do, if there was enough material.

Are you glueing the wood directly to the slab? Is that one of the recommended installtion methods?

Will the wood be installed into the room at the end of the hall and around the corner?

What does it look like when you turn to the left after coming up the stairs?

If you're a newbie a 45 degree installation may be a challenge.

I like the wood run the long way down the hall.

started down the hallway and into the room... straighest and longest line.

looks great so far. I'll post some pics when I get a chance.

Yes, share the pics. Looking forward to it. You can cheat a little bit with the bull nose(by angling so slightly to get all rooms to line up) but it sounds too late for that, unless you're talking about the 45 degree angles above the stairway...you're fine.

Here are some images.. (althought with a different camera that isn't as good as the one I used for the previous pics)....

That really looks good! I would have done the same...

With a lot of grattitude to this awesome site and all of the outstanding info and advice posted here......

I finished the floor and now need the stairs... But I'll start a new thread with questions for that...

Here are some pics... THANKS again to to Ken and every one who contributes to this site... I could have never done it without the knowledge and confidence I gained here...
