ask the question to all the other isps worldwide who have done just that. As everywhere else rolling it out in cities is deemed more economic.
Fastman2 is wrong in one crucial respect - our cities don't consist of mostly apartment blocks. The UK has one of the lowest proportion of flats in Europe, second only to Ireland **. We're incomparable with a lot of Asian cities too.
A lot of places doing FTTP have a lot of flats, and are really doing FTTB. It is nice of the good old' boys in the fibre council to consider FTTB as FTTH - they know what side their bread is buttered on.
G.Fast and FTTdp, when the DP is within 50-80m, isn't really much different from FTTB, but the ftth council won't include it - too many vested interests and history to contemplate inclusion of the mortal DSL enemy. They're already smarting from the fact that clever EU political target - 100Mbps to 50% - was meant to force FTTH deployment, by excluding DSL, but failed at that.
** For example, Latvia has 72% flats, Switzerland has 58% flats, we have 18%. Those places need good FTTB solutions; we have 59% in terraced or semi's ... we need the equivalent to FTTB to work in urban & suburban streets of such houses.
