Welcome! I do have some ideas here; your structure is very nice!
Having a solid roof is the best, for shade, and protection. Wide roof overhangs are better, can you still add them? More shade in summer, and weather protection.
Lots of ventilation is really Important, so having a big hardware covered window, or an open side, on your 'coop' area, will be good.
Consider the whole thing a coop!!! If it's built predator proof, it will be. In cold weather, doubled rolled plastic over the north and west sides at least , and part of the east side, will make it cozy.
Consider 2"x4" woven wire over the hardware cloth on the lower three or four feet of the structure. Extra safe!
Will you be moving it? Protection from digging predators needs to be done somehow.
Insulating the roof helps with summer heat, and shade plantings matter too.
