With surrounding airspace closed for COVID-19 we are working a higher than normal volume.  The situation was made far more complex when we got an aircraft FL360 non RVSM who needed direct ZZZ during the peak of the complexity.  I should have probably forced the aircraft down sooner than I did.  I think throughout; with the help of a trusty X side; we were able to maintain separation on everyone; but the volume level and complexity were super high.  The needing of the X side when we are being told to distance; but being so inundated with volume is tough too.  We must work to figure out a plan to utilize since other facilities will likely face similar fates.Recommendation: Work on trying to make some preplanned contingency plans since this crisis doesn't seem like it'll be over soon.
