Conservatory over drains advice
Andy
down part of the side of my house. This would be lean-to, bespoke,
around 4m x 2.5m, and separated by an outside door from the rest of
the house. The structure would be predominantly glass, with dwarf
walls of either brick or something lighter (e.g. wood) if poss. As far
as I'm aware, planning consent and building regs wouldn't apply.
My foul and surface water drains lie partly under the area and so I
need to build it to avoid damaging these and to allow access should
they need attention in future. I believe the drains are quite deep
(1.5m - 2m) where the conservatory walls would cross them.There is a
manhole, which would be located within the conservatory. I don’t
particularly want to have to dig deep foundations to bridge them, so
am looking for a lightweight construction, with some form of ‘raft’
base if possible.
Grateful for any advice.
Thanks, Andy

have to take your foundations down to invert level, and bridge over the
pipes with lintels.
If they're private drains, and if the soil hasn't been disturbed for a long
time, I'd ignore them and just build over them. If the manhole in the
conservatory provides access to a foul sewer, you'll need a bolted-down
sealed lid on it. Overflowing sewers are not very pleasant - I know, I've
had a few!

have an air tight cover installed, not just the smells but flammable gases!

The drains are my own and the manhole is for the foul. The soil
hasn't been disturbed for at least 13 years so maybe OK, though I need
to do a bit more investigation to guesstimate depths and runs.
Thanks very much for advice.

Hi Andy,for a start, if you are thinking of heating the conservatory
from your house central heating then you need planning permission
otherwise you will not. About the depths of drains etc. I would phone
and ask your local building control office and ask them what would be
required. About the drain cover then this will need to be replaced with
a 'screwed down double sealed' cover because it will be inside and you
could get smells coming into the conservatory. The min. fall for drains
I think is 1 in 40 so if you know the depth of your inspection chamber
then you should be able to see which way it falls and work out the
levels from that. I built my conservatory late last year and the rain
water pipes run through the walls so I had leave spaces around the
pipes, about 100mm all round and build in releaving lintels over them
with pea shingle around, leaving space over the top. If I was you I
would go for a strip footing with a brick or concrete block wall, a DPM
and concrete oversite to stop dampness getting in. In the winter months
I leave a greenhouse heater in there which switches itself on when the
temperature drops below 5c which keeps the windows clear of
condensation. If we are going to sit out there and it is cold then we
use an Halogen three bar heater which we found quite good, both are
really cheap to buy. I have been on forums where people have come up
with different ideas about heating but they say that the cost works out
about the same. I hope this helps in some way. Roy

Thanks Roy, this is helpful info.
I wasn't thinking of heating it from the house CH, just standalone
heating when cold.
I may be back to pick your brain again if plans go further.
Thanks, Andy

I�m thinking of having built a fairly cheap and cheerful conservatory
down part of the side of my house. This would be lean-to, bespoke,

I would move the drains, if yours and do a "propper job".
My next door neighbour finally moved the drains from inside his self built
conservatory after the 2nd time they flooded and filled his conservatory to
about 4 inches deep with yucky water. He had fitted a cover with a rubber
seal but under the pressure of water it just escaped around the edge of the
cover and top layer of bricks. Whilst moving the drains he discovered why it
blocked easily (and self cleared !!) a cracked joint allowing tree roots in
capturing disposible nappies flushed down by someone further up the row of
houses......

Sooner or later drains *always* need attention.
Its no big deal if they run under, but it is a big deal if they TURN
under. You need to be able to rod and that means a turn needs a manhole
cover.
If thats what you have, get digging. It really is NOT that big a deal,
whilst there isn't a conservatory there.
With drains, they need to run straight under the building to an outside
manhole cover, were at least if the Turd Army attacks, its outside.
