Situated in the center of Bricktopia Park, the Tree House Cafe is constructed in a massive oak tree that has been hollowed out and reinforced to hold the restaurant on top.
From an engineering point of view, the Tree House Cafe is the most complex building in Bricktopia.
It is constructed in a non-orthogonal, octagonal shape. Each wall panel is fastened to its siblings by a single stud on each edge. Additionally, several beams stick out to connect with centrally located, internal structural members in the ceiling and floor. The green columns hide the seams in between each panel.
Each window is framed by arches. The bottom arch is mounted upside down and is attached to the rest of the structure with technic pins.
To make matters more complex, the bottom of the restaurant sticks out in a skirt-like structure. This is made up of a separate set of panels attached to the main unit. Each of these separate panels has a beam sticking into the central structure. This beam has tiles on the top and is held at the correct angle by brick pressure. Although no studs connect, these skirt panels are held tightly.
One can see the spiral staircase leading from the park to the restaurant dining room.
