That's 2 Castle Gate pieces next to each other. Its a 1x6x18(Plates), also note that bricks in Bedroom are hovering just above the ground, the gate on a flat ground would have the spikes hidden.
At the moment I need to/someone to make a proper Special brick of it, its coughing out that there's something in its way but I think they'll be fixed with a proper special brick. Also I didn't want to add detail to a nearly 200 poly brick, that'd just be stupid D:
Though not a car gate, still a gate :3
