Dennis,
Here is a pic of the blocks. The wall is 7' high. The blocks are 8 x 8
x 9. One side is vertical, the other is tapered. The top course of
blocks comprises bell shaped copingshttp://lh4.ggpht.com/tonyjeffs2/SQh76eiqCvI/AAAAAAAAARU/-RsN4U-ZHgg/s...

Jim,
I did check with planning.The planning requirements changed at the
beginning of october. We're allowed to take it outwards by 3 m without
planning permission, but we want to take it out 4 metres so do need
consent. The total floor area is 12m.
I think you have a point though about the whole thing falling in on my
head - if I don't get the join with the garden wall right, that could
be a source of endless damp problems!! :-/

Here's a mockup of roughly what the conservatory will be like, but
without that silly peak on the roof.http://lh3.ggpht.com/tonyjeffs2/SL_u.../I7sHDuErSng/s...

Hi tony

Ah OK so Planning is required but I doubt they will be that interested
in the construction details as that is Building Control - who (at
least when I did mine last year) are not legally allowed to be
interested unless structure more than 30m2 as long as mainly
transparent etc (& other easily met conditions).

Pic looks interesting - is said wall to the right? does it slope away
from your side to "hold" next doors yard/extension up? Who built it?
is it on your land? - have the neighbours built on top of it/used it
as support for extension? did they have permission? any paperwork/
deeds for it?

I spose at end of day if you can't take that possibly retaining(?)
wall out and rebuild it *solidly* in a vertical fashion to all's
satisfaction, you will have to just make the best of it, leave it
alone and build right up against it?
To me it seems unlikey you'd gain much space even if you did rebuild
it - as you could bet your neighbours would involve Bldg Ctrl who
would be interested and they'd probly make you build a replacement as
thick if not thicker!!

Cheer
Jim
