Hello.
I will soon demolish an old concrete balcony about 2x3 m.
Will build a new one in wood.
Now to the question:
How do I demolish the old one without getting hurt?
It is attached to the wall and stands on 2 posts at the end.
If I start chipping away here and there, it will eventually be like "sawing off the branch I'm sitting on."
Below, there is an old concrete patio that also needs to go.
It's hard to explain.

Understand what you mean. Could you perhaps rent a small excavator with a pneumatic hammer and chip away with it from ground level?
We had a scaffolding set up with the floor of the scaffolding about 1dm across the balcony floor. Just tilt aside a floorboard and chisel with a rented Hilti, larger model.
The balcony was so well reinforced that it was possible to stand on it even when all the concrete was gone. Protect the facade and windows below the balcony, larger pieces of falling concrete can make substantial holes.

Isn't it possible to build scaffolding and place the decking just below the balcony?
What is demolished just falls down a bit and then you can throw down the concrete more controlled.

Plywood/OSB to cover what needs to be protected....then build a scaffold so you can work from multiple sides.....

Everyone seems to be into building scaffolding, which I was also considering.
Plywood in front of doors and windows was a good idea.
Do you think a Hilti 905 would be enough? The concrete is about 10 cm thick.

Yes, that Hilti will probably be good...make sure to have at least two different chisels...

Now it's getting close.
I've been thinking about how it's attached to the wall.
I haven't removed the eternit yet, so I haven't been able to look.
Does anyone have experience with this?
As mentioned, it stands on 2 posts at the outer ends.
Is there a sturdy angle iron in the wooden frame, or how was it usually done in the 1940s?

Are you sure that your floor structure is made of wood? Otherwise, the balcony might be an extension of the concrete floor structure.
