How much would a 20 Metre Wall cost to build? (garden wall)

Danny_G

Does anybody know what the rough quote for building a 20 metre wall would be?

-4 meter trench dug
-20 metre length wall
-2 metre high wall
-Breeze blocks used / double wall (2 sided wall)
-Its a garden wall, where appearence isn't that important, hence using grey bricks.

even if approximately ££, ?


or is there any website which has guides of prices for things/walls like this? (I cant find one - but perhaps you know one)

Danny_G

anybody? your views?

thanks

4 metre trench? Deep? What's that for?

Anyway, pulling fingers from [STRIKE]my backside[/STRIKE] the air;

4m trench - you'll be looking at hiring a minidigger, then? I'm assuming this is for the foundations - so you're looking at a depth of about a metre, and a width of between 150mm and 600mm (breeze blocks come in a range of sizes!). Assuming 300mm width, 1000mm depth, 4000mm length, you're looking at 1.2 cubic metres of dirt which is 2, maybe 3 tonnes - so yeah, minidigger and skip. Maybe 200 quid?

Don't know what you're doing about foundations for the wall so would assume that you're actually putting a 1m foundation in the whole way along (so 40m) - in which case multiply the amount of dirt by 10 - so 20 to 30 tonnes of dirt (12 cubic metres!)

Then probably you're looking at 750mm depth of concrete - about 9 cubic metres of it - at £100 per cubic metre that's £900.

Assume breeze block dimensions of 18"x8"x6" (450mm x 200mm x 150mm) - then for the length of the wall you'll need 40000/450 = 89 blocks, the height you'll need 2000/200 = 10 blocks - so 890 blocks per side or 1980 blocks altogether. Call it 2000 for round numbers' sake - at maybe a quid each that's another 2 grand.


So my back of an envelope calculations says it'd be about 3k to do it yourself, maybe 5k to get a builder to do it.

Although, as evoke has said;

the op requires a 3m deep foundation according to another thread....
as everyone has said, it would be best to get someone that knows what they are doing to spec the founds and the wall

evoke

He's not allowed to do it himself, as he has already been told in his previous thread on the same subject. It requires professional planning:

any wall higher than 1.2m, which most walls for buildings will be, must be professionally designed

And why he can't phone a brickie for a quote ot phone a builder's merchant to get the price of a brick, I have noooooooooo idea!

JEEZ!
