Knocking a block shed - best method

trickybicky

Hi all

I am planning on knocking down a shed in the garden.

The back wall of the shed is a boundary wall, the right side of the shed is built 4" block on edge against a boundary garden wall which is also 4" block on edge

How would I go about knocking the walls built side by side? I only want to knock the shed one?

Also all the walls are plastered, should I cut a line in the plaster before I start so I don't damage the existing plaster on the walls adjoining the shed?

What i would do is remove the roof first, And then i would take down the side walls using an Impact Drill. You can rent these from any hire shop prob about 20-30 per day.

Start at the top blocks then work your way down. Youll eventually be able to remove 2 rows at once when you get a bit lower down.

Depends how close the shed wall is to yor boundary wall? Is there a gap sufficient enough that hitting the wall on the inside wont impact the boundary?

If you're comfortable to use a con saw you could cut vertically, dividing into sections to weaken it. Should have minimal impact

This is a better idea ... brick by brick makes sense

Con Saw is alot of Tool for an amateur tbh. I wouldnt be comfortable recommending one to anyone who hasnt been around tools alot.

Thanks for the replies.

I have a cordless 18v SDS Hammer drill which I was hoping would do the job with a chisel point, even if slowly.

The walls are built tightly together from what i can see. The shed wall is 7ft, the boundary wall is 5ft. so It is going to be difficult to get access as I can only access from the shed side.

The shed wall is also acting as a pillar for the boundary wall as the original pillar for the wall would have been in the back corner where the shed is if that makes sense. So when i knock the shed wall I expect to have a pillar left standing at the back corner

I am half thinking of leaving the shed wall that is builty tight to the boundary wall and just bring it down to the same height.

I got a quote of €2k to remove the shed, rebuild the pillar if necessary and re plaster the walls, shed is 3m x 2.4m

I agree, I have used one before on site to cut rebar and I'm not afraid to say I didn't feel comfortable with it!

If needed I was going to use an angle grinder with concrete blade to cut 10mm vertical line (just the depth of the plaster) down wall so there is a clean line between the old plaster and new which will make a better finish when re plastering the walls once the shed is down.

If it was me it would be, block by block starting from the top down. Slowly but surely should remove them probably a lot easier than you would expect. I would hit (with lump hammer and chisel) downwards into the mortar which should not cause impact on the nearby wall. Don't know what you should do with the corner without seeing a picture. Good luck and remember do this slowly.
