Domicile: The Italian Skybox (low prim)

If prim count is an issue for you, if you want something cheap, stylish and classical, then you need the Italian Skybox from Domicile up in your sky.

It's 20m x 20m, just 6 (yup, six) prims, and features lush textures both inside and out. Best of all, it's out for just 25L$ (and it'll stay at that price).

So if you want a classy addition above your home for a romantic tryst, an elegant changing room, or a ballroom capable of holding a swathe of be-frocked and tuxedo-ed avatars, order your footman to purchase The Italian Skybox ;-)
