Unless I'm misunderstanding you, what's wrong with :
def dom(x,y): return 1 if x>0 and y>0 and x+y<4 else 0
region_plot(dom, (-4,4), (-4, 4))
(See Sagecell)
(Note that, since you are working on two variables, you should plot in 2D : There's nothing to specify a third dimensin...).

EDIT : Rececyphering your code, I guessed you may mean : "plot z(x, y)=(x*y*(x+y-4))^2+(floor(x/4))^2
subject to x>0, y>0, x+y<4
", inwhich case, what you are looking for is :
plot3d(lambda x,y:(x*y*(x+y-4))^2+(floor(x/4))^2, (0, 4), (0, 4)).add_condition(lambda x, y, z:x+y<4)
(see Sagecell).
(Note that the "condition" function is a three-argument one...).
