Answer
Non-aromatic
Work Step by Step
For compounds to be aromatic they have to pass three tests:
1) Planar- if not planar then they are non-aromatic
2) Hybridization- should be sp/ $sp^2$
3) Huckle's rule- for aromatic 4n+2= # pi electrons (should be a whole number when solved)
and for Anti-aromatic 4n = # pi electrons (should be a whole number when solved)
This compound is non-aromatic because there is a $sp^3$ carbon, so it fails the test 2.
