How does a duplex differ from a penthouse in terms of ownership?

A duplex is a two-floor apartment connected internally by a staircase, which can exist on any level of a building, while a penthouse is specifically located on the topmost floor and often includes exclusive terrace or rooftop access. Ownership structures for both are similar but pricing and exclusivity differ significantly.

Key Structural Differences

• Duplexes can be positioned on any two consecutive floors within a tower.
• Penthouses are exclusively located at the top of the building.
• Penthouses usually include private terrace or rooftop area as part of ownership.

Ownership and Documentation Aspects

• Both are typically registered as a single unit despite spanning multiple levels.
• Terrace rights in penthouses should be explicitly mentioned in the sale deed.
• Common area contribution may differ if exclusive terrace use is granted.

Pricing and Resale Considerations

• Penthouses typically command a higher price per square foot than duplexes.
• Duplexes offer more configuration flexibility across mid-rise floors.
• Resale demand for penthouses is often driven by exclusivity and views.

while both are multi-level living spaces, a penthouse's rooftop exclusivity and location typically make it a premium category, whereas duplexes offer similar living style at a comparatively accessible price point.
