As an AI language model, I don't have a specific knowledge of every duplex villa complex on the planet and their barbecue pit offerings. However, based on common barbecue pit types, these are some of the several available options that may be found in a duplex villa complex:
1. Charcoal grills
2. Gas grills
3. Wood pellet grills
4. Electric grills
5. Smokers
6. Hybrid grills (combination of gas, charcoal, and smoker)
7. Fire pits with grill grates
8. Built-in barbecue pits.
