Can someone tell me roughly how much a 28 metre long, 900 mm high (above ground) blockwork garden wall should cost using either Solid Dense 7.3N 140mm or 100mm concrete blocks please?

 

The wall is single skin, no render or coping required.

25.2m^2.

 

252 x 100mm Blocks @ 85-90p = £226.80 (maybe £252 for 140's)

£1 a block laid £252 Some brickies will want £2 a block (go jump) and some will take less - my brickie was £300 for 400 blocks laid absolutely perfectly!

 

£478.80

Call it 28m^2 for ease.

 

280Blocks @ 85-90p = £252.00

£1 a block laid £280

 

£532.00 - Some brickies will want £2 a block (go jump) and some will take less - my brickie was £300 for 400 blocks laid absolutely perfectly!

 

 

 

thanks and what about the foundation cost?

 

I have been quoted £3k by the builder that has done all the other building work for the house but thought it sounded quite expensive.

 

The wall will be retaining wall, so not sure if that means blocks would need to be laid flat or not

What's it being laid on and what's it for? 

 

retaining soil so that garden lawn is level with house floor. Laid on clay soil. The main house foundations required 3 courses.

You said above ground so I assumed you had something.

 

28m of found for that size of wall - depends, excavator or hand dug - found may cost you £1000.00

That ain't a garden wall!

 

Back to the drawing board!

 

Single skin 100mm block - no chance.

The wall would be at the front of the house in this photo, so that the lawn is the same level as the house floor. 

 

the wall would be at its highest of 800mm to the left of the photo and maybe only 400-500mm to the right hand side.

OK - attempt No. 2!

 

You will need at a minimum 140mm block with piers every 2-3m - so worst case 252 blocks for basic wall plus about another 120 block for 14 piers so £372 for block - £372 laid ton of sand and 10 cement £80-100.

 

Found - digging this will be the biggest cost - £1000.00 - £200-500 for a concrete depending on hand mix or trucked in.

 

I think 3K sounds fair actually. £1500 will be materials. 3-5 days work.

A lot of people say a lot of things. Our job is to find out what he really wants

There would be a hedge planted behind the wall as close to the wall as possible, so it would need to be level

You don't know until you're told. As far as @ultramods was concerned it was a wall in a garden. Fair assumption unless you know what the retaining part changes in the construction

Going off the point, but the build is looking good!

Cheapest way to do this is concrete Lego blocks. They have capping stones for the top. 

 

I done the same on a much bigger scale. Don’t need a SE design or foundation at your height if the ground is adequate. 

 

Digging could be done in a day with a digger n driver (£150).

or something that looks pretty like  marshalls dry stacking walling --do it yourself  in no time

https://www.marshalls.co.uk/homeowners/view-croft-stone-garden-walling

the layer above sits behind the lower layer so it locks together 

 i have used it ,water drains out through the gaps as well so no worry about a tsunami of mud

You’d get at least 40% more on site,with a continuation of work,fork lift bringing your gear AND a subbie making a cut on top. 

Go jump yourself :))
