Shoot the upper-right cyan rail and top corner so the right wall starts peeling away.
Break the next right-side brace to expose the top orange lintel and loosen the roof.

Remove the slanted orange roof piece and the loosened right column while the facade is leaning.
Clear the middle belt and the short upper remnants, leaving only the lower doorframe and side posts.
Shoot through the lower right column, then the left lower column, so the remaining base loses both legs.
Finish the last cyan cubes and small orange pieces on the wheeled stand; leave 3 balls.

Board notes 5 details

Layout: An orange-and-cyan gatehouse stands on a wheeled base with side rails, a top lintel, a silver-disc middle belt, and two lower door columns.
Goal: Break the right frame and roofline first, then tear down the lower doorway until the wheeled stand is empty.
Opening: Shoot the upper-right cyan rail and top corner to peel the outer frame and loosen the roof slab.
Danger Zone: The center belt looks tempting, but the side rails and lower columns keep the facade standing until one outer wall is gone.
Mechanics: A hollow framed facade that collapses once the roof lintel and side braces lose alignment.
