The Tri State Skyline World Tower is Danville's one and only best landmark, which is located at the near-to-the-MOAT edges Landmark Danville area. This building is a 840 high story vacation resort tower that resembles the building that's under construction, the Tri State Tower, the Burj Dubai, the Tokyo Sky Tree and the already built tower, the CN Tower. It is confirmed by Phineas and Ferb as the sibling to the Tri State Tower. The entire area of the tower is 4/7 indoors. There are many outdoor entertainments there, so do the indoor entertainment. It is also named "Tower Everest" because it's hight is tallest then Mt. Everest. Despite being very tall and high, it's also really safe, and was nicknamed "Doomsvault The Second". It is the highest building until, Landmark Danville Tower, which is still growing today. Unknown to Phineas, Ferb, and their friends, a very similar structure was built in ancient Danville known as the Sky Tower, a dungeon that Swordsman Jeremy had to go through and complete to continue his quest. The Sky Tower was built at the exact same spot this tower is today. (The Legend of Candace: The Sky's Blade) In InkPen's Battle for Danville, it's alternate-dimension self is blocked from the outside, while it's interior is used as a base for the Resistance.

The Orb Penthouse

Phineas, Ferb, and their friends suite. It's situated on the very top of the tower (as in like, the sharp point at the end of a needle). It can be only accessed by Phineas, Ferb, Isabella, Baljeet, Buford, Django, the Fireside Girls, Dill, Perry, and another agent, Perry Jr. by three secret ultra high speed elevators and one prototype "Monovator", a newest line of elevator that uses the same technology as Monorail trains use. It's only one floor. Access to the Penthouse is also granted into all Fanon characters.

Security of the Penthouses

As security is their top priority, Phineas and Ferb agreed to install the only best elevator for this purpose, an elevator proved to guard Dill in the neighboring tower, The Tri State Tower. The elevators only service the three VVVVVIP penthouses, in the center of the Grand Tri State Park Resort. No one else unregistered can gain access to the penthouses, because the security system uses three confirmation steps. First, ID cards, second, the newest Phineas and Ferb invention. The Three-Finger-Swipe trackpad, which tracks fingerprints from three fingers. And third, password. No one can ever perform a security breach, even to the exit doors, which lead to the rooftop Helo hangar. The Helo hangar is a hangar for helicopters when not in use, and it opens when a helo took off or land. Only 4 elevators service the three areas of the Penthouses.

Everyone except other "visitors" can gain access to both The Lab and The Orb. Dill rarely stays here. He stays next door, in the Tri State Tower.

The Lab

The lab is a lab below the Skyline Penthouse, where only people from The Orb Penthouse and selected people can gain access to.
