Simply Build It

Direct reply to your question - you need a 75mm cavity and to fit clips on wall ties to hold the insulation against the inner cavity.
Depends what you are doing but if it is a house extension you need to meet regulations so thickneess of insulation will depend on construction esp inner leaf.
