The Esparina Condo offers dual keys, which are units with studio apartment attached. From the layout shown above, it is a 3BR dual-key unit. (2BR+1studio)
The main door leads to a common foyer, with another 2 doors. One of the door leads to the studio apartment (shaded in light-brown), while the other door leads to the 2 bedroom unit.
These dual-key units are designed for families to stay with their parents, without compromising privacy. The studio apartment will have its own living space and kitchen, and the 2 bedroom apartment will have its own living space and kitchen as well.
An additional benefit for dual keys is that, the studio apartment can be rented out, as it is considered as a “room” instead of a “unit”.
