Default Raised patio - solid or deck on legs?

I'm thinking of building a rear-garden patio raised to the level of the
interior floors, the idea being to be able to walk though the patio doors
with no step down. The height above the existing ground level would be
almost exactly 24 inches.

Decking on legs is presumably a practical possibility but I rather like the
idea of a solid construction with a paved or stone top surface. Since this
would, I assume, have to be built onto the external wall of the house, it
would breach the damp proof course. A boundary wall of brick or blocks
could be built with a matching DPC, but what is the usual arrangement for
the solid infill? An overall membrane that covers the entire area? Or
something else? I would have to trunk out the present airbricks, but there
seem to be materials specially designed for that.

Alternatively, could a solid patio be free-standing, separated from the
building by a small but definite air-gap?

Many thanks for any thoughts.

The pressure treated wood is **** these days.
They have done away with the copper and arsenic so it rots PDQ
You can put in a vertical DPC also make sure the surface of your patio slopes away from the house to drain rainwater away.

Decking will probably the least problematic regards the CPC and blocking the air vents. If as you seem to prefer something solid then why not combine the two by building your patio separate from the house thus leaving an air gap which could be bridged with a short section of decking.

Strictly speaking any deck higher than 300mm above ground level needs planning permission and I also think building control approval.

The regs refer to "Putting up decking, or other raised platforms." I can
see that covering raised decking or a retaining wall, infilled and
covered, but do generally raising the ground level, with no retaining
walls and putting a patio on it count as a raised platform? It probably
does, but I don't know.

Many thanks to everyone for the replies. I do in fact have planning
permission for a raised patio though the design submitted was slightly
different from the version I'm thinking of now. I don't know if the changes
would be sufficient to warrant submitting an amendment, though.

The question about raised flower beds is an interesting one; I have two
such, also around 24 inches high, and I'm afraid it didn't occur to me to
seek permission to build them.

Definitely not required for them. It was brough in to stop people
standing or even sitting on raised decking and overlooking a neighbour's
garden, invading their privacy.

While you might climb onto a raised flowerbed to dig it, you are not
standing around chatting and drinking there and taking a good look in
neighbouring gardens.

My thought is that you don't want decking as its a haven for Rats and the
decking will need replacing a few years on. However you do not say which way
your garden slopes, and whatever you do there is going to have to be steps
or a slope down to the garden too.
I see alot of patios made as you describe, with no obvious step, so it has
to be possible to do without having damp issues.

But of course nobody really bothers. You only need to look at the back of a
few houses in this road, and most of them had it done with no planning
application. Some of the issues created for the neighbours has caused
friction and flooding though so one has to be mindful of removing current
drainage situations or indeed building walls between properties with hole in
them for the water to flood next door!

It never ceases to amaze me the messes people get themselves in over a
stretch of concrete or paving.

Brian,

I see a lot of patios made as you describe, with no obvious step, so it
has to be possible to do without having damp issues.


Thanks for that, and your other thoughts. The exact arrangement of steps
down to the garden level is something I'm still working on: in a wilder
moment it occurred to me that raising the level of the entire garden could
well be a simpler alternative, even with all the other complications it
would bring, though I suspect I'm really straying into the realms of fantasy
with that one.
