Drone videographer Matthew Roberts has posted a new video on his YouTube channel this morning, covering the ongoing progress of construction at Apple's soon-to-open campus, Apple Park. A few weeks ago, Roberts posted what was expected to be the final update before Apple Park's grand opening, but the campus still hasn't opened its doors to employees with just a few days left in April.

Ever since Apple officially announced the name for Apple Park back in February, construction on the site has ramped up rapidly over the ensuing weeks. Today, solar panel installation on the roof of the central "Spaceship" building appears nearly complete, while the courtyard of the building is still seeing major construction related to the large pond and surrounding greenery.

Landscaping everywhere on the campus has been expanding over the past few weeks, so much so that Apple has caused tree shortages for other companies in the area. In Roberts' newest video, it's evident that there is still much time left for Apple's landscaping to be finished, which will eventually end with 9,000 native and drought-resistant trees spread across the site.

The continuation of landscaping, as well as construction on some of Apple Park's auxiliary buildings, will continue into the summer, well after Apple moves the first employees into the main building. While some of the side buildings are complete -- like the parking garage -- a few still have a ways to go, including the new campus auditorium, which has been named the "Steve Jobs Theater" in honor of the late CEO.

Once employees begin moving in, it's estimated to take Apple around six months to move in all the workers coming to Apple Park, which will number about 13,000. Earlier in April, another well-known drone videographer, Duncan Sinfield, shared off a video of what Apple Park looks like when it's lit up at night.
