Guys ... appreciate your thoughts...
I need a bit more house room...
Been working from home a while and really need a
separate small office...
and SHMBO would also like a utility room off the
Kitchen...

House viewed from above...
is L shaped with garage/dormer bedroom
Garage is a double... (forms the leg of the "L")
Sloping roof with a dormer bedroom on top...
rear wall of garage adjoins living area...
no current access from inside house...

I was thinking of a garage conversion...
either

a) Simplest... changing double to single... to leave a
usable single garage I guess the garage half would have
to be slightly more have half (say 8.5ft?) which would
leave (after a robust partition wall ... double skin?)
about 7.5 ft for living areas which I would divide into
2 rooms (say 7.5ft x 8ft),
enter first (utility) from new door from house... then into
second (study) from utility...

b) My preferred...
Extend front of garage by about 9ft... Partition off about
9ft off the back of the garage across whole width and split
this into the two rooms...

Benefit of b) is that a double garage is retained...
And two rooms are slightly bigger... and I have enough room on the
drive
to extend and still get 2 cars side by side on the drive)..
Disadvantage is it's a bigger job, will need roof reworking
(either re-sloping existing... to cover or putting a separate
pitched roof over garage extension)....

I spoke to a "garage conversion company" and awaiting them to
send someone out... but over the phone they were only interested
in doing the former... claiming it would add value to the home
.... and said the second option would not
(But I don't think they wanted the hassle of the extra work)....

So any thoughts?
Is either worth doing... considering the small (but very useful)
amount of extra space (any experience of likely costs NW UK)
Are either likely to add or detract from future resale value...
Or should I look at other things (perhaps even moving...
Currently got 4 bedrooms but all in use for a few years until kids
leave
.... smallish back garden... little room for extension there)...

Thanks
