Interesting idea for a carport at

Looks very sharp--however from an engineering point of view the foundations would need to be well designed--especially if your site is exposed to wind

Looks like a bloody great metal sail to me!

I'm visualising one of these in Wellington in a howling Southerly!

And my mind's eye is showing me a kind of sick blend of parking a car and Kite Surfing......
.... I know this can't end well :-)

Imagine the stresses on concrete base over time.

It looks nice but long term is it wise?

Lamp posts stand up in wind despite just being a pole set in concrete, but I remember (from a summer job long long ago when I really did install lamp-posts) that even the little suburban street one needed a 60cm deep hone, and the big highway ones needed 1m to 1.2m.

This carport has a far greater surface area, so will have far greater windage, so may need 2m holes.

Given the poles on this are only 2.7m long, then by the time you've secured it in 2m holes it will be 0.7m off the ground - great for limbo-dancers parking skateboards, but not for the rest of us.

Ha - what a laugh...nice looking agreed - but it certainly would be put to the test in Wellington. I can visualise it flapping up and down in the wind before breaking off and taking out your car.

$3600 for the canopy - $10,000+ for the reinforced foundations.

Cheers,

Donna

The difference is that lamp posts have very little surface area for wind to catch. With a sail between them, there is a massive surface area for the wind to put pressure on.

definitely needs one. as it exceeds the 5sqm limit of coverage.

I actually saw one of these in front of a villa on Tinakori road in Thorndon last week.

They'd used a half length one, and buried the columns so low that you could only park a small hatchback under it, and it curved down so low over the boot you couldn't actually open the boot once parked.

Didn't really work for me.

I think I've seen the same one with a porsche parked under it. It looked like it fitted quite well but I can see the problem with a higher car.

Quite ok, has four portals and probably all structural steel has a 20mm webb, so very stable, and able to withstand huge wind BU's.

I can see the bonus of it without having legs one side.

very common in japan, someone must be importing the kits. some have removable extra posts for winter when they catch snow
