As realalemadrid says.
Have you checked with the builder
if the houses in the new build will be able to get FTTx?
FTTP requires the builder to have designed in and installed the ducting and underground boxes. Very few seem to do that.
FTTC requires there to be a FTTC cabinet already serving the precise location, because if there is just a phone cabinet (PCP) it won't necessarily get a fibre companion for ages.
