I have an almost identical run in the link (it's my small run). It differs by not having the 'house bit' but did have the option of part floor which I never use as it takes up grass area. Still use it when I haven't an extra person to help me move the big run.
My big run is carpenter made (ebay bargain old couple got equiped for guineas then ill health made them decide against the idea). Big run is at least 3 x 5 and includes a house. Lazy littles buggers do have regular naps in their house during the day.
Hi there, our run was identical to this, I painted it with cuprinol before the girls got inside it ( obviously!!) to give it some protection, it was pretty sturdy and the nice thing about the shape is that cats can't sit on the roof and intimidate the guineas when they are inside it! It might be once they get used to it they will venture out more and start exploring - you could also let them free range a bit inside the playhouse if it is not being used and is secure. These type of runs are not really safe enough to leave guineas in over night though, foxes and rats will always find a way in, and they can be tipped over with enough strength, - I was more than happy to leave mine in during the day and whilst I went out but brought them into the shed at night. Maybe a smaller night hutch inside the playhouse at night would help?
We had a big square run from pets at home, called the Rose Run. In that I put a small hutch that was a box basically with a ramp to the ground, which had a lid on hinges too so was very easy to clean out. I can't remember where I got that from from. I also put a big sheet of wood on top of the run to give them a bit of shelter and stop any would be predators from getting in.
My guineas loved it and would stay in that all summer long. They both lived until they were 8 and 9 so were happy with their lives.
I think it is nice for them to be out and about in the summer - and I am sure they could manage such a short wide ramp ninja its the steep one in double storey cages which is more problematic for them - mine used to kind of jump into the shed ( not high jump, but even so!).
My concerns about them being in a wooden cage in such a secure looking run would be the temperature and also if other small /large furries could get in at night- I used to have ours in a shed, but in a huge hutch and when ( if) it ever got too hot would have to kind of prop the door open so they didn't over heat at night. < we were in NW. I think this happened 5 times in 10 years!!!!>, but as Kahlua says, they can be happy outside if they are fox proofed, suitably 'ventilated' and regularly checked on ( 8 or 9- those are very impressive ages)!! , so I think your arrangement would work well. You could try freecycle or gumtree for the hutch to go in the run, and put chicken wire along the edges so furries with long tails couldn't get in....... good luck!
Ninja I've got the ramp in your link (IIRC it's about 84"x48") and as it's sold as a rabbit run, it's a good height. We use metal tent pegs to secure it (there's no base which is ok for gP but I don't know if rabbits could dig out).
The advantage is- it's huge, we put loads of tunnels and boxes inside (vary to keep the lardy boars interested) It folds flat, so easier to store. DH didn't want to be painting wood every couple of years. When we had a leaky Pighouse roof (at 9pm one Sunday night last year) we put the rabbit run in the garage (not the cars home but concrete floor) with a load of cardboard and a huge bag of hay and straw to cosset them.
The triangulr run would be easier to move in Summer when the soil gets hard, it's a blighter to get the pegs in.
When we bought ours they recommended NOT to use the little wooden houses at the side. So we wired the side doors up and use the other two. Shame because I liked the little housie but maybe there wasn't enough to protect them from foxes/cats/escape?
