Oh yeah, that is a lonely place out there. Probably Chris' friend
doesn't get bothered by door-to-door sales people a lot :-)

Never made your own ductwork? When I was a kid in Jr. High and High
School, sheet metal shop was a requirement for all males (before equal
rights... the girls had to take Home Economics ;-)

Since this would be at mild weather and/or attic exchange rate, I'd
guess a 1000-2000CFM squirrel cage would do it. I'd probably use 4
20"x30" A/C filters (in an array).

Sure I did. But you can't get the proper fans with filters up front. I
mean a kind that would pass inspection.

Pleated filters in an array for outside air intake would get expensive.
At least around here.

You're putting the filters in the wrong place.

(1) EXHAUST blower in attic blowing out an external vent.

(2) Electrically-controlled louver to connect to interior AC ductwork,
sucking house air out into attic, then to outside world.

(3) Inlet to interior of house from outside, somewhere (me, I might
just cut a "window" in the side of the house ;-) outfitted with
filter(s).

So use cheapy fiberglass. (Pleated might not pass enough air anyway.)

Right, a man can be alone with his thoughts etc :-). Total removal from
all the mental noise of the city. The reference I gave was the roof of
the rebuilt croft house and it looks like they have a path north now to
get vehicles through. The house is on the north west side of the loch,
with the main road to the south south east side and another house just
off the road. Between the two houses runs the original path round the
loch, to the east.

I'd live in a place like that tomorrow, but it would get the veto from
my other half and it's really just a bit too far away from civilisation
while i'm still doing client work. Lack of broadband would be a
significant problem as well, though there are several satcom ip vendors
around now and the costs have come down. (Yes, i have looked into it
:-). Always wind though and you could most likely get enough power for
most stuff from that, solar and heat pumps.

Somewhere on the border area between wales and england looks like the
most likely scenario in a few years time. Perhaps Shrewsbury area. Cape
Wrath in the highlands was not received enthusiastically when I
suggested it and the N York moors is all yuppie prices now...
