Flooring for raised patio - opinions wanted

[John D.]

Hi All-

     I am in process of building a raised patio at my primary residence.  The kitchen and family rooms will open out onto a 30'x15' patio that is the same level as the house floors, but about 2' higher then ground outside.

    I'm trying to figure out what to do with flooring.  I don't want a rough finish pavers would give -- I'd like to be able to step out in bare feet comfortably.  I would also like to find something that won't be really cold to the touch ideally.

  Any recommendations on something that would give the polished finished feel of an indoor floor, stand up to the snow and freezing weather, and ideally not be super cold to the touch?
