A duplex is essentially a single unit, with two residences that share a common wall. Townhouses, on the other hand, are a row of homes, with each unit sharing a wall with their neighbour. A duplex can also be a building with two separate apartments with one above the other, each having its own entrance. While duplex units are usually sold to a single owner, a row of townhouses can have individual owners for each unit. Both types of units come with their own advantages, but in the UAE, the inventory of townhouses is higher than that of duplex units. Check the best areas to rent a townhouse in Dubai.
