I have a wall that runs along the entire length of my property next to the street. I want to saw a hole so that a car can be driven in and parked on the property. I'm planning to rent a motor saw and cut from two sides.
The wall is made of concrete and I'm having trouble anticipating how difficult it will be. The hole needs to be 3 m wide, so I assume it's not enough to make two cuts and then try to topple the wall. Even if that were somehow possible, the piece I've cut out would be too heavy to remove.
Should I cut out narrow strips of the wall? How do I remove the remnants at the bottom if the wall breaks above ground level?
Does anyone have experience or can provide tips?

Start with three vertical cuts and a sledgehammer. If it doesn't work, you may need to make more cuts. If you are somewhat strong, you should opt for a saw with a 400ø blade, as it will cut about 15cm in on each side, but it is noticeably heavier. What remains above ground can be filed away with the saw if you're a bit careful; otherwise, you can tackle it with a smaller demolition hammer.
The biggest issue I can foresee is getting neat finishes on the tiles.

The absolute best look is to rent a saw that is large enough to cut the entire wall from one side; the cuts look best this way. Shred the wall into suitably sized pieces so that you can load and transport them away. Is it possible to excavate on the inside so that you can make a horizontal cut at the bottom?
It usually costs quite a bit to rent such a large machine; check with a company if they are interested in cutting up the wall for you while you transport the remains yourself.

Thanks for the response. I was thinking of making the cut so that it fits with a whole tile, or alternatively trying to knock off the last one and then put in a new one.
Maybe it's not worth the trouble to take it on myself after some consideration. I'll check with a company to see what it would cost to saw it down if I remove the remains myself. Can I dare to guess that 5000 kr would be enough?

There are saws for concrete that you attach to a rail to achieve straight, fine cuts. A motor saw is not entirely easy to cut straight with. Husqvarna has a saw called a ring saw where the blade does not have a central hole, so you get more cutting depth. The advantage is also that such a saw does not have a gyro effect, making it easier to cut with. But it's probably harder to find for rent.
All serious rental companies should have access to ring saws; the last place we rented from at work had two.F Fredrik_Lerum said:
With a ring saw, you must ensure you have plenty of water and be even more careful as it can easily bind and break when it binds.
