papers and the scrawled:

a) Is it possible to get an offset adapter to go from 4" to 3" -
"in-line" ?

Yep. All the 4" - 3" adapters I've seen have been offset, whether this
is just conicidence or a standard fitting I have no idea but they are
available.

b) Am I going to have problems obtaining 3" pipe & fittings ?

Shouldn't have thought so, try a local plumbers merchants and see what
they say. If their answer is "yes sir, we keep 3" pipe and fittings in
stock and on the shelf" then job's a good 'un.

c) Can the pipe pass out through the gable end of the bungalow (I know
about the restrictions re opening windows) - or does it have to go out
through the roof ?

Pass.

d) If it goes through the roof - is this just a matter of removing a
concrete tile and fitting one of those
'ali-sheets-with-a-rubber-collar' efforts - does the ali sheet replace
the tile ??

Pretty much, I did the same here for the boiler flue and it was just a
case of remove tile, cut felt, insert flue, slip collar over and
fashion to approximate tile shape. There may have been some silicone
involved although I don't think that's strictly neccesary.
