Open up wall, advice needed

[Stabbsson]

Hello forum!

My wife and I are planning to open up a wall between the living room and the kitchen (i.e., not demolish it 100%). You can see the red lines.

The house was built in 1971, and the walls consist of Tretex > Råspont > Horizontal studs > Råspont > Tretex. How would you say it's easiest to open it up? To get everything as "straight and nice" as possible, support studs and door frames need to be put up. The Råspont is 15mm thick and I'm 99% sure there are 45mm studs inside. And the Tretex is about as thick as drywall, around 13mm.

Reciprocating saw? Circular saw with a guide rail on the wall? Planning to leave about 25 centimeters from the exterior wall (left) and leave a bit of the ceiling, though haven't decided how much yet.

All tips and advice are welcome, I have two 1-year-olds, so I want to minimize dust but also get the job done fairly quickly without dragging it out!

Hello

If you're sure there are no cables, pipes, etc. in the wall, and that it's not load-bearing, I would go ahead with a circular saw with a track.

Edit: I just noticed that there is electricity to consider.
Disconnect and check to ensure it doesn't lead anywhere else.

Hello

As long as you're sure there aren't any wires, pipes, etc., in the wall, and that it's not load-bearing, I would go ahead with a circular saw with a track.

Edit: Just noticed there is electrical to consider.
Disconnect it and check to ensure it doesn’t continue elsewhere.

I'm aware of the electrical! There's a switch + outlet on both sides, and it's 100% not load-bearing, that's been confirmed.

But are there circular saw blades that go that deep? Or are you thinking of sawing from both sides of the wall?

Set the circular saw to 28mm, screw a straight board onto the wall as a guide and follow up with a vacuum cleaner.
