Conservatories - is this good or bad?

message from N. Thornton on 20 May 2004
Hi

May I ask about an odd conservatory idea, as I'm a bit unclear.

Imagine a small conservatory, say 50 sq feet, located at 1st floor
level, on top of an existing 1 storey ground floor room. It would be
up against the boundary line with a neighbouring property: lets
imagine that they agreed to it. Distance to road maybe 8 feet or so. A
new doorway would be put into the outer wall for access.

Now I know this may sound unlikely: the question is, is there any way
by which this could be done? I would expect the answer is no, but you
never know.

Regards, NT

I am pretty sure that this one would switch on a need for both
planning permission and building control because it's not ground
floor, though......

I am impressed with the approach.

Thats creative :) But it would mean burying the existing floor, plus
creating a retaining structure on the boundary to avoid burying the
neightbour. And it would necessitate a tunnel to get out the back door
:)
What you suggest almost suggests that one could build a small tower
block if you had your own digger with which to bury each successive
layer of building :) I cant imagine theyd really buy each one being
ground floor development.

BTW the ground floor room is already there, so no cantilevers would be
needed.

Whats the PP and BCO situation with underground extensions, or a
separate underground storage room? Its ok, I wont be asking about
tethered hot air balloons :) Its nice to check out some potentials, as
if there are any I would look into it as a self build.

Thanks Owain. These points are easy to deal with in this particular
case. Windows would be provided at ground level, in the roof of the
underground room, and would be used to provide means of escape as well
as light and ventilation.

I assume such underground structures would be covered by BRs and maybe
PP as well: that is my first question for now. If they are not, I will
investigate further sooner. If they are, I'll investigate further
later.

This idea would be outside of the house structure, and intended as a
storage room, but of course if it can be made habitable that would
make it of significantly more use. It would be quite close to
boundaries, and road.

Just what rules cover this sort of thing? Are underground sheds/stores
allowed?

Reminds me of a lecture theatre at Southampton University, which completely
sticks out of the side of the building, over a campus road. It's supported
by a cantilever arrangement, and is perfectly safe, but they had to install
dummy posts at the corners because the cleaners wouldn't go in it! If you
look closely, they don't quite reach the bottom of the building they are
supposedly supporting :-)

And the Adelphi Hotel in Melbourne, where the rooftop swimming pool is
partly cantilevered out over the edge of the building (the pool also
has a suspended glass bottom so you can enjoy the view straight down!)
