Can anyone confirm please what materials and quantities i would need to install a base for a single storey extension to be used as a utility room
Just want to make sure when i ring my local builders merchant that i ask for the right stuff !

Also, would it need any steel mesh in it ?

Dimensions would be approx 7.3m x 2.5m and as i say, its just a single storey

thanks in advance
