Concrete Blocks Vs Breeze Blocks

[Chit]

Hi all,

I'm looking to build an outbuilding at the back of my garden later this year when it heats up again but am unsure as to which material to use to build it?

The outbuilding will be used partly as a summer chill out room and partly as storage area with a small workshop.

I'd like to install shelving units and screw these into the walls for stability too.

I'd rather just have 1 skin of breeze block/concrete block on the external walls and so am wondering if concrete blocks would be the best things to use? As I'm not a builder, I'm not skilled at laying bricks/blocks and don't want any unstable walls and so am liking the idea of the larger 9" sized breeze blocks rather than using the thinner 4" concrete blocks to construct the walls out of.

But when it comes to shelving and racking, I'm not sure that the breeze blocks will be up to taking these screws?

The blocks will also be rendered on the outside and inside so as to give them a nicer look and make them waterproof.

Which blocks would you guys suggest? Which do you think would be better suited for this application?

Many thnaks.

Use 100mm medium density concrete blocks or maybe consider timber frame. Whatever you do don't use lightweight.

Breeze blocks have not been made for many years.

thanks for that, what makes you say this? Also, the longest wall will be 7 meters long. Would a 4" wall be strong enough to not be pushed over by the wind etc?

By breeze blocks, I mean the celcon type blocks

Lightweight blocks will easily crack. A 100 med density block wall will be fine at 7m long with a couple of piers spaced evenly.

Cool, thanks for that.
