What does "new build" add to the price?
New dwellings against existing homes — same postcode district, same property type, same year. Every sale in Price Paid Data is flagged new or not, so this is a direct comparison rather than an estimate.

How to read this
A new home is not the same product as an old one at the same address: it is warranted, insulated to current standards and needs nothing doing. Some of this gap is that, and some is the premium developers can command for it. The register records neither specification nor condition, so the two cannot be separated here.
Comparisons are held within one postcode district, property type and year, so the figure is not distorted by where or when the sales happened. Bulk transfers and nominal consideration are excluded. Source: HM Land Registry Price Paid Data — licence and method.
