First and foremost, think about what you plan on doing with your new shed. This factor will determine whether you'll need windows, electricity, plumbing, and so on. A shed with loads of windows is preferable if you're using your shed as a living space, reading nook, a mini home office, etc. Windows let natural light in, increase airflow, and create a bright and fresh interior that provides feelings of comfort and serenity. On the other hand, a windowless shed feels more like a dark and stuffy room with poor air quality. That is totally fine if you're only going to utilize your shed as a storage space but, if you plan on staying in there for more than a couple of minutes at a time, you'll certainly need windows. You can even create an extremely relaxed space by installing a skylight window. Moreover, those who want to live in their shed full-time should include electricity and indoor plumbing for a more functional living space.
