It's a nice looking coop, and I'm sure it seems quite roomy to you. However, 42x42 is just over 12sf, and the three sections of run, at 36x32 each, total 24sf. Chickens need a minimum of 4sf in the coop, plus 10sf in the run, per chicken. As is, your setup is barely adequate for three chickens, and that's only if they get lots of free range time. You said you plan to free range them when you're home? Do you work typical 8-5 jobs? Get home around six? It gets dark around 9 or so, which is when the chickens will naturally put themselves to bed. Which means they will get barely three hours per day of free range time. I would recommend either only getting 3 chickens, or getting another coop and more run sections.
