# Can someone help calculate number of blocks i'll need

#### Neil-UK

Hi

Im having a double storey side extension and single storey rear extension built (planning just been authorised)

Im trying to put together an accurate material budget but im struggling to calculate the number of blocks i'll need.

The two storey side extension is 4.5m wide x 8.9m deep
The single storey rear extension is 8.7m wide x 3.3m deep

I beleive the wall is to be double skin cavity (concrete outer blocks and breeze block inner)

The foundations are ready mix concrete pour so not using foundation blocks

If anyone can assist me to calculate a rough number of blocks i'll need id be very greatful.

Best Regards
Neil

10 blocks per m2.

Work out your wall area, and deduct the area of openings

Thanks woody.

Do you have any idea how many blocks a bricky can lay in day?

If he's on daywork, as few as possible. If he's on a high pricework, as many as possible.

There are too many factors, and the only meaningful way is for you to get several compartive quotes

I would be organising it on a job price rather than daily rate, I had a guestimate of 400 blocks per day providing conditions are good and no major problems to hold him up....just wondered if my guestimate would be ablout right.

Works out im gonna need 2600 blocks

400 blocks a day, 15 pound a metre... ill come and do it! haha, think 400 is a bit much unless a very long run with no corners, scaffolding or loading up... even with a carrier on your own itd be hard work!

If you want a proper price, then I would give you individual prices for m2 of walling, cutting and laying reveals and cills, laying and fitting DPC, fixing insulation, fitting lintels, fixing wall starters, building in ties, fixing frames or dummy frames etc etc.

Then daywork for waiting, sorting out discrepancies, dealing with problems and BCO etc.

So be careful just how much you try and screw the builder down, as it is not always a good thing to base everything on price. Base it on trust instead
