Building over a patio

[WIllTry]

Hello

I’ve searched and searched but cannot find a suitable answer to my question so hoping someone with more knowledge about this stuff than me is able to help.

I have a patio that has been laid with sandstone. I recently built a wooden gazebo and would now like to add a built-in kitchen/outdoor bbq area under the gazebo. I’m thinking of a brick or flagstone structure with a concrete or tiled worktop, built-in has bbq, and perhaps a small pizza oven. So quite a heavy structure.

Would it be okay to build this directly over the existing patio, or do I need to lift the patio and lay a new foundation to support this structure?

Much appreciated!

Depends who has laid the slabs I guess.

Never a good idea to trap the slabs down. Take them up and do it properly.

It will be ok.

Be more concerned with setting the gazebo alight.

It will be ok

Depends which they get bored with first.

Thanks for the replies. I’ll build over the patio but will try to spread the load as much as possible. It’s also been suggested that I drill in a few rebar rods then pour a base foundation on top which seems like a good idea.

A good idea if the oven is going on the side of a vertical cliff or something.

By this I assume you mean that the rebar and foundation is a bit overkill, is that correct?

Perhaps I am over thinking it but it’s the first project like this that I’m attempting and I really don’t want to screw it up!

Btw pizza oven is no longer in the plans. Just an l-shaped kitchen / counter with an integrated 5 burner gas bbq. Still a heavy structure though.

The rebar will be doing jack.

Whether the kitchen needs anything to spread the load will depend on the kitchen. The are ways and means, but without knowing exactly what you are doing, that's as good as you'll get.
