Hi, I'm trying to estimate the cost of materials for a workshop in my garden.I need about 650 concrete blocks 440x215x100mm. I want the exterior type not the featherweight insulating ones.
Has anyone bought any recently and know what price to expect for this sort of quantity. I've seen a 1 off price on line of £1.12ea but I rather hope they will be much cheaper in quantity.
TIA
Bob
