Not sure where you're looking but they're definately houses.

extended line from Mill Hill East.
Just because they're square doesn't mean they're flats. They're
houses. Though
looks like there are 4 in the way, not 2. Even so, still irrelevant in
the
scheme of things. Maybe a million or 2 to buy out compared to the cost
of the
extension which would probably run to 7 or 8 digits.
Still don't see what you would achieve by extending unless you could get
across the M1 to the main line.
This argument is cracking me up. I'm trying to picture the architects of
the M1 saying "We can't build a motorway from London to Leeds because
there are 37 railways in the way."
It's not that the M1 is an insuperable barrier but the only point in
extending the Northern Line from Mill Hill East would be to link it to
Broadway station which lies the other side of the M1/A1 corridor.
There's also an extensive housing development to negotiate, presumably
in tunnel, before that. Oh and Spud's two or four houses actually near
the tube station.
Oh and the architects of the M1 probably said, don't worry about the
railways they'll all be gone in a couple of years :-)
If there was demand for the Northern Line to go to Mill Hill Broadway, a
tunnel would be dug. Single would probably be enough, although you'd
want to redouble the surface part from Finchley Central to Copthall. But
the fact that they've never bothered putting an interchange by Colindeep
Lane where the Edgware branch crosses the Thameslink route makes me
query the business case for a Mill Hill interchange, even if a surface
alignment could be found and the existing bridges were double track.
Precisely my point. It is relatively trivial from an engineering point
of view to get the line from East to Broadway, it just takes money but I
can't see that there is any business case for it. Apart from a putative
link to Copthall stadium where is the traffic going to come from to
make it worthwhile doing? Rugby Union crowds are still a fraction of
those attending soccer matches. A couple of thousand fans once a
fortnight between September and May is not a major traffic flow.
Incidentally, I just realized how ironic it is that Belsize Park had
deep level shelters constructed beneath the Northern Line platforms,
when they could have dug two platform tunnels on the Thameslink line and
used them as shelters instead. Although, perhaps they wouldn't have been
deep enough for the purpose, and their construction would have probably
required several months of closure of two tracks on interrupted
operation of the Thameslink Line.
The Northern Line tunnels were, of course, intended to be part of a post
war express line.
