Horava gravity theory possesses global Lifshitz space as a solution and hasbeen conjectured to provide a natural framework for Lifshitz holography. Wederive the conditions on the two derivative Horava gravity Lagrangian that arenecessary for static, asymptotically Lifshitz spacetimes with flat transversedimensions to contain a universal horizon, which plays a similar thermodynamicrole as the Killing horizon in general relativity. Specializing to z=2 in 1+2dimensions, we then numerically construct such regular solutions over the wholespacetime. We calculate the mass for these solutions and show that, unlike theasymptotically anti-de Sitter case, the first law applied to the universalhorizon is straightforwardly compatible with a thermodynamic interpretation.
