It's either jusqu'à or jusque chez. You can't have both. Which preposition is the correct one is determined by context, e.g.:

Vous allez jusqu'au bout de la rue. -- You walk up to the end of the street.
Martine est allée à pied jusque chez Julien. -- Martine walked by foot to Julien.

Note that using jusque adds a sense of "right up to" or "all the way to".
