Gaming room/guest room in the basement, is it well thought out?!

[ekstrjoh]

Hello,
I want to start by saying that I love reading in this forum, better than fiction.

Now to my plans for a room in the basement...

Conditions:
Villa in Bromma from the 1930s
Drained and platon plus insulation 2007
Uninsulated slab

My first thought is that half of the basement space (2 rooms) should be heated with radiators, not underfloor heating, while the remaining area should eventually be equipped with waterborne underfloor heating according to best practices (chiseling, gravel, insulation, reinforcement, casting.....). What do you think about this, right or wrong?

Then to the room in the basement (Motto - "nothing organic in the basement"):

WALLS:

• Plastered walls that are starting to peel at the bottom. It's likely because the house was undrained for 70 years. Anticimex has been here with a moisture meter after drainage, 0-strike!
• All loose plaster is removed and thus left as is.
  
• Install a steel rail with 4 mm "foam paste" in the ceiling and floor, place a 5mm support pad under the rail every 500mm to create an air gap.
  
• Frame with steel studs cc 450mm, blocks for elements and equipment that will be wall-mounted.
  
• Prepare device boxes and conduit pipes
  
• Minerit on the two outer walls is screwed into the steel stud, and 40mm foam board is also glued on the back (I have the idea that it should "save" the acoustics somewhat, right or wrong??).
  
• The other two walls are fitted with regular 13mm gypsum, of course framed in the same way as before.

CEILING:

• Lower the false ceiling with regular wooden studs and then cover with 13mm gypsum
  
• Install ventilated ceiling trim

FLOOR:

• Lay a type of platon on the floor against the slab (Beijer Hässelby has discontinued platon), then fold it up against the minerit and gypsum boards on the wall.
  
• Over the plastic sheet lay 40mm foam board and then wood flooring directly on this to avoid the feel of a basement floor.
  
• At the fold-up, mount ventilated floor trims

Alternative for flooring: Is it risky to lay chipboard over insulation and then wall-to-wall carpet instead of wood flooring?

Then all the electrical and so forth comes in, but that's not the primary concern....

This became a lengthy letter, but I hope you can have some comments on my approach.

Best regards, Johan

No one has any comments?

I know there are several threads addressing this question, but I thought that if this summary of the procedure is accepted, more people might be able to carry out their basement project in a similar way.
