[IDEM libro secundo de omnibus tribunalibus. ] §50.16.198.pr'Urbana praedia' omnia aedificia accipimus, non solum ea quae sunt in oppidis, sed et si forte stabula sunt uel alia meritoria in uillis et in uicis, uel si praetoria uoluptati tantum deseruientia: quia urbanum praedium non locus facit, sed materia.
[THE SAME in the second book on All Tribunals.] By 'urban estates' we understand all buildings, not only those which are in towns, but also if by chance there are stables or other buildings let for hire in villas and villages, or if there are manor houses serving pleasure only: because it is not the location that makes an urban estate, but its character.
proinde hortos quoque, si qui sunt in aedificiis constituti, dicendum est urbanorum appellatione contineri.
Accordingly, it must be said that gardens also, if there are any established within the buildings, are included under the designation of urban estates.
plane si plurimum horti in reditu sunt, uinearii forte uel etiam holitorii, magis haec non sunt urbana.
Clearly, if gardens are mostly for revenue, perhaps as vineyards or even vegetable gardens, these are rather not urban.
