Damp-proof New Garden Shed/Outbuilding

[mattprince]

Hi,

Doing a 5mx3m shed/outbuilding at the bottom of my garden to house my tools and for a general workshop. My current wooden shed is rusting my tools crazy so want to do this to combat that.

I was going to get normal breeze block to build it with,single layer. Will this combat my tools getting rusty and not let water through?

It will certainly perform better than a timber shed but you will need to make sure you have some form of insulation and heating and also some ventilation to create a better environment for your tools.

Would thermalite blocks be good enough?

Thermalite blocks would be a good choice but I would consider rendering the outside face to avoid them "sucking" in rainwater.

The only way to prevent condensation is to make sure nothing in the shed ever is cooler than the dew point. This normally happens when the air temperature increases quicker than the items can warm up as they have more thermal mass. In practice that means some insulation with either heating or dehumidifier, but if you were really smart you could use thermal mass and solar gain cleverly to keep things warm enough.
