Here's the various hutches which have been built around here. It's not for the same climate nor the same level of predators you may have in your area, though.
https://hillsidefarmhawaii.com/pages/hutches/hutch.html Each time a new hutch is built, new things are learned.
In general, though, the first thing that will rot out will be the floor of the hutch. Having that easily replaceable will allow your hutches to be useful longer.
If you're breeding rabbits, then a rat proof nesting area is essential, IMHO. Depending on other predators in your area, you may need some more substantial housing. The biggest predator we have around here is the neighbor's dog and since the rabbits don't run or react to the dogs, so far the dogs haven't done anything to the rabbits if/when they get out of the neighbor's yard. If dogs were a possible problem, I'd run lines of barb wire across the bottom of the hutches, but so far that hasn't been necessary.
We have one hutch for bucks, it's divided into six 'holes' so we can keep up to six bucks. Since they're all in their own space and all bucks (except for the occasional visiting doe), they don't really spray much. Not exactly sure why, but I'm suspecting the lack of nearby females may have something to do with it. The females have a big community hutch and they get along pretty well. There's a bit of chasing now and then, but there's hidey holes and a ledge in the big space so they can chase and hide. Sometimes one doe will be pushed away from the food dish often enough that she loses condition, though, so when that happens the skinny doe is given her own separate space. Otherwise community space is an easier way to keep multiple buns.
It's about time to build a new hutch, though since it's been about ten years and the bunnies are being moved to where we're building a new house. I'm not sure if the new hutch will be double layer like the old one. Cleaning between the layers is most of the maintenance work on that style of hutch. Single layer hutches take up more space, but less work.
There's also a new door hinge system made of just two big nails. On the next hutch, it will be hinges made from a pair of big nails but with a washer between the lower hutch frame and the door. That will provide less friction between the door and the frame. The "2 nail" hinge system is a much less expensive "hinge" than actual hinges. Other than costing a whole lot more than two nails, the store bought hinges rust out after a few years.
Another nice thing with a hutch is to put in an automatic water system. Depending on how many rabbits you have, washing water bottles or filling water dishes can take up a lot of time. Not sure how it would work in cold places, though.
Sometimes they'll still spray, but at least it doesn't cover the other rabbits if there's a divider. They'll still know there's a doe on the other side. 
Solid dividers also prevent or at least reduce barbering, fighting, and/or nipping through the wire.
