As an AI language model, I don't have the ability to specifically determine the interior or exterior design of a villa, thus here are some of the common types of blinds used in duplex villas:
1. Roller Blinds: These are simple and cost-effective blinds which are made up of a single piece of fabric rolled onto a tube and can be operated by a pull cord.
2. Venetian Blinds: These are horizontal slats typically made of aluminum, wood, or PVC and can be tilted to control light and privacy.
3. Roman Blinds: These are soft fabric blinds that fold upwards when raised and stack neatly when lowered.
4. Vertical Blinds: These are vertical slats typically made of fabric, PVC, or vinyl that can be rotated to control light and privacy.
5. Panel Blinds: These are large panels of fabric that slide along a track and can be used to cover large windows or as room dividers.
