Know any £125k flats on sale today?

No, but that wasn't the point

which was:

showing that there are 400K+ flats available doesn't negate the claim
that the average (median) price is now 250-300K

In the two developments mentioned by Colin, or throughout the City?

city wide

Remember the context: this is about how much a flat would cost if a
builder had a brown fields development under way at the moment.

IME Developers want to charge premium prices for their new-builds far
in excess of what they cost to build

The price is based on the cost of the land, plus s106/affordable housing
stealth taxes, plus the cost of the access roads, utilities and bricks
and mortar, plus a modest profit margin.

whether they get away with it depends upon the strength of the local market

I agree that the cost of the bricks and mortar for a typical Cambridge
brown fields site is perhaps a third of the selling price, but it's only
one of the many contributing factors.

Rather than bang their head against a brick wall (cheaply built or
otherwise) developing sites where no-one has the funds to pay for the
resulting properties, they bide their time.
