The best view yet of Apple's new 'Spaceship' campus that's beginning to take shape

Construction is well underway for Apple's new circular "Spaceship" campus, and a recent drone flyover courtesy of 9to5Mac gives us an excellent look at the project's progress in stunning 4K HD.

The futuristic Apple Campus 2 is designed by Norman Foster's firm, Foster + Partners, and will eventually feature curved glass panels, an underground parking lot, a private auditorium for keynotes and product launches, and a 360-degree view of nature.

Here's what it'll look like when it's complete.

Apple has been sharing photos of the construction from time to time, but 9to5Mac reader Brandon Elwood has gone one step further and stealthily flown a drone over the construction site to capture a video of the campus from multiple angles.

Apple has continued to make progress on the circular main "Spaceship" ring of the headquarters, with the new addition of concrete floor panels, and the video also shows some close up shots of the construction in progress.

Past drone videos have also revealed that significant progress has also been made on Apple's $161 million auditorium, an underground theater in which Apple will eventually unveil new products and hold press events.

Here you can also see the circular lobby of the auditorium taking shape.

The campus will also feature two above-ground parking structures, and the first parking structure is nearing completion and will soon see solar panels installed on the roof.

While there's still a ways to go before Apple's new campus starts to look like the concept rendering seen before, a fair amount of progress has been made since construction began, which you can see below.

Work on Apple's new headquarters is slated to conclude in 2016, and you can see a full timeline of its construction over at the official Cupertino website.
