Is it possible to attach an annotation to a new object?

Let's say we have a simple house object, House house = new House () and annotations @Large and @Spooky.

My idea was to have a switch statement so a house marked as @Spooky does something different than a house marked as @Large.

@Spooky
House house = new House();

System.out.println(house.getClass().getAnnotations().length);

Apparently there is no annotation on my new house object as length == 0.

Why is that?
