ProDave Posted Friday at 18:40 Share Posted Friday at 18:40 A part of my build that is still awaiting to be built. And a good job as the parameters have changed as I hinted in another thread a few days ago. It now needs to be built a bit higher than originally planned to accommodate the latest addition to the fleet. It's almost 3.2 metres to the highest point so we need comfortable clearance under for that. The size remains the same, 6 metres by 6 metres. The original plan would have been sloping down from the front to the back, but that would make the front insanely high now, so it will now slope from the garage wall down towards the left. It will be roofed with box profile roofing as originally planned. I will sketch a proposed joist plan in due course to bounce ideas around. But one thing that has become obvious, the car port roof where it attaches to the garage is going to be above the MVHR vents. I am not sure if that is going to pose a problem or not?

Iceverge Posted Friday at 18:50 Share Posted Friday at 18:50 I would be worried about some future owner running a car in there on a cold morning to warm it up and the fumes getting drawn into the MVHR. Could a stand alone structure work? Or you could always extend the MVHR inlets out to the fresh air above the new roof . Link to comment Share on other sites More sharing options...
ProDave Posted Friday at 18:58 Author Share Posted Friday at 18:58 I could extend them (externally) one to the front and one to the back so they were not actually under the canopy. The front one visible is the exhaust, the rear one, hidden in this picture is symetrical so the same distance is the inlet. There will be a small gap anyway, to avoid trying to form any sort if flashing from the wall to the roof. Link to comment Share on other sites More sharing options...
Russell griffiths Posted Friday at 20:04 Share Posted Friday at 20:04 You will need next to sod all fall if using box profile sheets. Link to comment Share on other sites More sharing options...
Oz07 Posted yesterday at 09:41 Share Posted yesterday at 09:41 Just been in Australia and nowadays for their patios they are using all these insulated roofing sheets. They seem to be able to get massive spans without intermediate joists or purlins. Possibly worth looking into very simple construction. Saying that you do get big snow loading presumably so prob a no go Link to comment Share on other sites More sharing options...
JohnMo Posted yesterday at 12:49 Share Posted yesterday at 12:49 Stick big 500W plus solar panels on the roof? Link to comment Share on other sites More sharing options...

Russdl Posted yesterday at 14:27 Share Posted yesterday at 14:27 How about a freestanding carport, half a meter or so away from the house so the MVHR isn't affected. Park the truck the other way round and have a slight fall front to back. Link to comment Share on other sites More sharing options...

Park the truck the other way round and have a slight fall front to back. There will likely be a gap but it can't / won't be that much, the supporting poles will be attached to the garage wall for stability. The whole point of buying this particular type of truck is you can wind he legs down and demount the camper unit from the truck, and use the truck on it's own as a normal vehicle. So parking the other way would mean driving out onto the grass to demount which would not end well in winter when it is wet and soggy. 1 Link to comment Share on other sites More sharing options...
ProDave Posted 20 minutes ago Author Share Posted 20 minutes ago First stab at joist plan for the car port roof There will be 6 posts "P" 3 each side, probably 150mm square all supported on post feet. The 3 at the garage ends will also be bracketed to the wall, to locate them, not to take any weight on the garage wall. The 3 at the left hand free standing end will require some diagonal bracing. Box profile roofing from the garage high end to the free low end. Probably with a small gap at the garage end to avoid having to flash it to the wall. Total size 6M by 6M. Box profile roof needs supporting on joists running across it, so in this case front to back joists. Assumed at the moment 600mm centre to centre spacing they are Joists B in this plan and each need to span 3 metres. I don't think these are going to be difficult. The problem ones I think will be the 4 "Joists A" that have to span 6 metres and support the smaller joists. This is the one I need some design input to see if this proposal is viable. I would rather they were not too deep, say no more than 8" / 200mm. But I do expect to double or even tripple these, and there is the possibility of a steel plate between them to make it a flitch beam? Ideas please?
