Calculating the cost of apartment materials?

Question

Mathematics

Come buy an apartment. And they tell you the price is ten million greenbacks.
Let's leave out the details about the scenery, renovation, layout, transport and a good view from the window.
We take a purely hut, for example, in Moscow from a developer where there are bare walls and we need to calculate the price of materials and work.
The work is separate + - estimate, we are here after another.

What variables should be taken into account?
Here is an example that comes to mind
1 - area, of course. Ceiling and floor
2 - material (brick, gas-block, etc.)
3 - wall thickness
4 - balcony
5 - windows

That is, we evaluate the beggar, nothing more.

It is worth remembering that when above you and below you, your beloved neighbor, it turns out that both of you are paying for materials and work. roof / floor / walls are shared. This will be needed later to divide the cost by 2. For example, the price of materials for the floor, stove, 5,000 USD. on your area, but who lives under you, it turns out 2500, but the ceiling, if you are on the last floor, then everything is 5000.

An example of a hut.
1st floor, area 30 m / sq., height 2 m, white brick material, wall thickness 35cm (conditionally 2 bricks, which means the price of the wall x2), one large window 1x2.5.

Or how would you calculate?

Answer 2

I would consider the whole house: how much materials, work it took. And he divided it by area - after all, they sell exactly “sq.m”.
The declaration of the house indicates its area: residential, non-residential premises. General - halls, entrances, fire escapes, attics, basements. Owners also pay for them by buying empty sq.m.
