Was just reading a post from a couple of weeks ago where Jeds stated that:
My house is a semi and it desperately needs re-rendering. Render is missing in places and alterations (blocked up doors and windows) mean new blockwork that needs rendering.
My walls are solid and so would need to be insulated externally. Any insulation added externally to my property is going to leave a substantial step at the party wall line.
While I would love to upgrade the U-value of my walls I think it will look appalling. Are building control really that keen on this issue?
Technically speaking building regulations requires you to consider upgrading the overall thermal performance of the walls. This applies to any situation where you renovate more than 25% of the surface area of an element - which is obviously the case here.
