"Puis-je venir chez toi ?"
This is a polite and direct way to ask.
Here are some other options:
* "Est-ce que je peux venir chez toi ?" (Is it okay if I come to your house?)
* "Tu veux que je vienne chez toi ?" (Do you want me to come to your house?)
* "On pourrait se retrouver chez toi ?" (Could we meet at your house?)
The best choice will depend on the context and your relationship with the person you're asking.
