Deck over existing raised area

[terryhawkins]

We have a raised walled area in our garden which I would like to deck over.

I'm OK with the decking part, but I'd be grateful if someone could say the best way to get a solid frame built on what is already there.

I would like the existing brick to be wood covered so I need a slight overhang from where the existing wall is.

Here's a photo of what it's like at the moment...

you will need planning permission as its more than 300mm above natural ground level

unless the back edge is natural level off course then its 300mm from the highest point

Really? Even though the higher level is level with the front garden? It's actually a step down between 2 different natural ground levels.

In which case it should be fine, any ideas about the best way to create the frame?

It's in the back garden, but the raised area is the natural ground level (level with front garden and roads etc. It then steps down into the back garden.

I won't need planning permission based on what you've said and what I've just looked up.

Just need the best way to create the supporting frame over what is already there.

4" posts into concrete.

And I think he's right, for what its worth - the drop will mean PP - a pain, I know. Or ignore the issue and keep fingers crossed etc...

Just my 2p

4" posts into concrete.

At the back and the existing wall end? I was thinking that the wall would be a suitable support for the front of the frame, or will that not work?

 

[terryhawkins]

Would it work if I was to attach 4 inch posts to the front of the wall and let the wall take the weight of the deck?

I could then attach the joists to the posts on the wall (wall takes weight) and attach to posts at the back of the deck?

Thanks

If the wall is sound then attach the frame to it ising rawl bolts or a ledger board (plenty of posts on here covering either metod).

Or, if you have any doubts over the wall, sink supporting posts into the ground at strategic points.

I need to attach the posts to the face of the wall to bring the deck to where I need it, and allow the boards to be attached to the face.

I have looked at rawl bolts but they seem to work with thin materials.

Are there any fixings that will go through the 4 inch post and fix strongly into the brickwork?

Thanks in advance.

For a similar job we used expanding bolts (some retailers call them expansion bolts). The only difference is we didn't want to hide the retaining wall, it is actually higher than the decking level, we attached the decking to it.

I'm in the process of planning out the deck, and would like your thoughts on this frame...

All posts are 4x4, and the joists are 6x2 (it's not to scale, its just a rough mock up with dimensions marked).

Will it be good enough to support the deck?

I would be inclined to have 3 beams across, not 1.

dont forget noggins.
