Floor, deck and bi fold door project

[Zebt]

Looking for advice/thoughts.

I am intending to install a hardwood floor (60sq metres) on concrete slab which should be pretty flat, thinking of Australian native spotted gum, in addition as I will be purchasing the timber all in one go (cheaper?) I want to install a 30 sq metre deck plus bi fold doors (currently aluminium patio doors installed) the intention is to open up the complete patio window area, it's an apartment with garden, the deck will be the same width as the bi folds which in turn is the same width as the living area. I will get the doors made and installed professionally.

What order should I do each job?
The patio windows have a 2 metre overhang, I would like to have a flat threshold but worry about water ingress during storms?
Should I go with a polyurethane glue plus the odd nail, or go the traditional nailed floor, there are no apartments below me? I need to check the threshold height onto the kitchen tiles and into the bedrooms, which I guess will determine how much depth I have to play with.
I will have the help of an experienced builder and others. Plus of course my Festools!
I'm guessing I can lay the floor then get professionals in to sand and seal?
Of course I am trying to manage the cost!

Cheers!

How thick is the floor?
Do you nail it or have it float, shrink/expand, in order to move on its own?

Ergo: I would be more tempted to suggest that you sand and finish it yourself.

Laying hardwood flooring on course concretes asking for trouble. Without a vapor barrier of some sort that concrete will just pump moisture into the wood.

Personally I'd tile or lay laminate. I know it's not what you were asking but it's a real concern you need to be made aware of.

Yes, I have heard of moisture being a problem but the slab is not on the ground, below my apartment are store rooms, I also intend to check the moisture levels in the slab before install.

Not sure on how thick I will go for on the boards.

The acid stained or epoxy painted floor can look quite nice.
That still leaves the deck though.

Gotcha that's a whole lot better at least. You might be able to seal the concrete with something non film building and still be able to glue to it. One of the supply houses around here carries caulk called chemlink that ic seen setup in high moisture conditions and still grab. You could glue and screw (tap on) some 3/4" plywood to the concrete slab and then lay a vapor barrier on top of the plywood. Then you've got something good to nail to and a block for the moisture of the slab.

Alternatively you could put down dricore subfloor with the little rubber feet and a vapor barrier on the slab. Depends on your budget and how high you can build the floor up before it become an issue with doors.
