Have you looked into Rex rabbits? Many people who have allergies do better with Rex, due to their low shedding. Regular cleaning and an air purifier may also help. I'm allergic to both rabbits and hay, but I've noticed the simple difference of hay type helps a lot. Timothy hay what most are allergic to. However, not only is orchard grass less dusty, but an allergy safe alternative.
Rabbits can tolerate cold, but as @Weeg and @HappyClucker7 have said, rabbits do not do well with heat and can suffer from heatstroke. For this reason, if outdoor housing is the only option, an AC unit or other cooling methods may be needed for those warmer months of the year.
Though that still leaves the issue of predators. Rabbits can die of shock, so even an animal trying to get into the hutch could kill your bunny. Hawks, coyotes, raccoons, weasels, stray cats, and dogs could potentially become a threat to your bunny. Any hutch you can buy from the pet shop, farm supply store, or online is going to be much too small and will not protect your bunny from these predators. They're like prefab chicken coops, they simply are not suitable.
The space is really the biggest issue. Rabbits are a lot like cats and dogs when it comes to care and space requirements. A large indoor play pen and space to free roam is the ideal setup. It's much safer, cheaper, easier, and of course closer to you.
A premade hutch is often not going to have the room for a large enough litter box, hay, toys, hidey houses, food and water, while still leaving play space and room for the rabbit on top of that. It would quickly become crowded and the rabbit won't have space to exercise.
These are the hutches I'm talking about
Rabbits can also become lonely out in a hutch. You could adopt a bonded pair, but in a small hutch they certainly would not have enough space. And you likely will not have the relationship you want with a pet rabbit. Rabbits are full of personality and some can be very affectionate. But when kept in a hutch, away from you and your family, you probably will not get to see that. Rabbits that are not socialized with people can become fearful, and a fearful rabbit can become aggressive. Not all rabbits are like this of course, and a fixed rabbit is more likely to be friendly. But in my opinion, keeping them outside and away from you somewhat defeats the purpose of having a pet.
All that being said, there are some outdoor enclosures that can be safe and provide everything needed for a healthy and happy bun. Like with chicken coops, they need plenty of space and predator proofing, which you can't get with prefabs.
Shed conversions are perfect for rabbit houses though. These ones in particular have a run attached where the rabbit can get some fresh air.
Being able to walk into it going to make it much easier to clean up after and bond with your rabbit.
There are lots of ideas on Pinterest, and if you'd like I can share my board with you where I have lots saved.
But of course, something like this is more expensive than the other options. Which is why the easiest and most affordable option is to house your rabbit indoors. Playpens can be purchased on
Amazon for around $40, whereas a prefab hutch or cage is going to be much more. Rabbits can be easily litter trained, and with a bit of bunny proofing, they can free roam the house just like a dog or cat.
Honestly, I would look into fostering first. There are lots of rescues with rabbits in need of homes, and fostering is a great way to help and find out if a rabbit is right for you.
If you have any questions about supplies or care, feel free to ask or PM me. I hope this helped give you a bit of insight on indoor vs outdoor enclosures
