In that case why not just a small specimen tree in the middle?
Make a ring of gravel round it having underplanted it with bulbs perhaps. Not daffs cos they just look messy when finished but crocus would be nice and you don't have to do anything to them. You could have spring and autumn flowering ones to extend the interest.
Either go for a small tree that is amazing at one particular point in the year or one that gives you something to look at all year round. I planted a Cornus mas varieagata in a similiar sized space. It has blossom in the late winter early spring, beautiful white and green leaves follow that and in the autumn has cherry like red fruits. Only bare for 2/3 months of the year. The tree reaches about 15ft but takes an age to get there and maintenance? Zero.
Once you've done that you could get artistic with more gravel or pebbles or boulders...maybe some of those rocks in the corner...Some kind of ornamental feature perhaps, birdbath, sculpture, whatever. And always keep the hedge neat and trimmed...makes such a difference.
Heres a few ideas to play around with...
Maybe no tree and just a bit of topiary. Scroll down to the one with the box balls...bit of maintenance but not much
Bit more edgey perhaps...
