Building a Pergola

I think he means just have the posts sat on the slabs directly. The weight of the pergola should ensure that it doesn't move around and providing drainage is good then there shouldn't be any issues with rot as the posts shouldn't be sat in puddles of water.

Wouldn't try that here, windy as anything some days

Bit of wind and it'll be gone.

Is everyone fixing their sheds to the ground then?

A pergola with a solid wooden roof would weigh more than enough for it not to get blown anywhere, especially given it's all open sides so the wind generally passes through anyway.

Must be some decent winds to take a pergola made from upwards of 100x100 timbers. Really low sail area on all the pergolas I have seen. I agree with @Martynt74 - wouldn't your shed be at more risk?

Aye another contender, thanks

I'm basing out off of a design that has slats on the top and some of the side areas, I'd rather be safe than sorry tbh.

I see your point, I'm just not convinced, not sure why

I'll also go with a less extreme example of a garden table. Sure my chairs get blown about in heavy wind, but my table never moves and it probably weighs about as much as a single 3m length of 4x4 being made of aluminium.

Your table is low down not 3m up in the air exposed to more wind, and yes sheds should be anchored down. Surely you've seen pictures after a storm of loose sheds battered about.

The lad I was talking to has had his pergola up ages and the bottom is only secured with wood screws to stop it creeping. He says the pergola structure/frame in itself is solid enough to treat it as a "big table".
