I have never build a sub before, but would like to build a hometheater sub in a Ikea Besta cabinet.
Would a 56x36x42 be enough for low hitting sub?
Or would I need two cabinets combined?
I was thinking of a downfiring sub.
Any hints or tips are welcome.
(For example which driver to take 🙂)

I'm going to assumes your measurements are in centimetres. Regardless, without substantial modifications your cabinet will likely fall to pieces. Every panel would need to be glued and additional bracing would be required.
I was thinking of making the box in the cabinet.
Not use the cabinet itself.
Yes dimensions are in cm 😉
It can be done, but the construction guidelines still apply. The driver is is irrelevant because the situation cannot be realistically modelled. To give you an example . . . In the bedroom I had an 8" sub in a cube cabinet. My partner complained that it was ugly, fortunately it was a snug fit into the bottom of the night-stand. Result: no sub-bass, but a horrific peak around 80Hz making everything sound like it was being played at an 80s wedding reception. Most calculations are made using the assumption that frequencies travel exclusively through air - they do not. Lower frequencies travel by all and any means.
The subwoofer argument is eternal: do you want 'true' bass or 'more' bass. Lock a subwoofer inside your freezer and your audible bass will vanish. But the items on your cupboard shelves tell you : your 15Hz response is phenomenal!
Too deep?
The answer is try it and see
Is this a floating cabinet? You will add a lot of weight to the construction. I would put a ported 12" subwoofer in there, as a sealed 15" might not fit given your measurements.
I would first try if this is the best location for your sub before building it.
And you might not need to build a cabinet in a cabinet, putting in a solid back and some 45's in the corner should get it airtight, add some dovel panel bracing and you are good.

Some interesting calculations: A 4'x8' sheet of Formica laminate is about the same price as a Besta cabinet, but the outside is only about 13 sq ft, less than half a 4x8 sheet. I would probably just make a sub that works and cover it, or some other finish.
Also, big speakers in a small box sound bad. Efficiency aside, decide how big the box can be and then pick a (smaller) driver that works in that size box. Cheap 2.1 computer speakers have amazing bass for their size. Note they are always ported.
