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