Yes the property is built from scratch, it could be a sole place of residence, social housing and various accommodation that are zero rated.
New build homes are zero rated and do not attract VAT. If your supplier supplies and erects the timber frame house (either a kit or a custom design) then they would do not charge VAT. If they supply the timber frames but do not erect them on site then they must charge VAT but you will be able to claim back that VAT from HMRC within a three month period once a completion certificate has been obtained.
If you have any other questions, please ask me before you rate my service – I’ll be happy to respond.
