Site gates are great. Pure 'form follows function'. In fact, it's function where form didn't even bother to follow, it stayed in bed and watched The Jeremy Kyle Show (it doesn't get up for less than its day rate). These gates are the perfect emblem of budget constraints, and what can be achieved with a tiny bottom line.
Development in the natural world relies in taking the most from the least, by travelling the shortest distance, by expending the least energy. Behind these functional closed doors lies the heart of a project where the rest of the money's been spent, so these gates need to work to the same laws of nature and perform as the definition of a gate, nothing more, but also nothing less. To protect the rest of the project (both in the budgetary and security sense) and to work to best to their ability, they must be durable enough to withstand constant use and the elements, and secure enough to keep out the riff raff. Because they do the job so well, they command the respect that a rococo door just doesn't for this application. Therefore the viewer is asked to think about a new layer of aesthetics that goes beyond attractive by visual definition.
In your face ornate wrought iron gate. In. Your. Face.
