I really like the roof of the structure, with the slight amount of rust. My only suggestion is that the building seems to be sitting dead center, kind of an inanimate object with a lot of mass for the frame.
I think maybe an application of the rule of thirds could help here - breakup the centering and place some of the elements in an off-center arrangement to make the composition a little more lively.
Another idea is to use strong perspective to focus on something near, middle, and far revealing details to get a sense of place and space. I think you are shooting high and hitting the stucture dead flat in the front. Front shots are good for close cropping and geometric repetition, but here you might take advantage of getting low with a wide angle and hit the building at a 45 degree angle, so you can see the detail in the ground, the grit in the stucco front, and maybe leading to the water and towering trees in the distance.
You are shooting at the right time of day; I can see the warm yellow cast to everything. I can see some really neat and strong shapes against those bright red doors: have you ever tried just a composition with the red doors and the interplay of shadows as a black and red abstract?
