The development consists of 86 apartments in four low-rise blocks set within spacious landscaped grounds with their own swimming pools and leisure areas. It is comprised mainly of two-bedroom apartments, all with two bathrooms and large terraces, although there are also several three-bedroom duplexes which overlook the golf course below as well as penthouses with large terraces on the upper floor. The ground-floor apartments all have their own garden, more than 100 square metres in one case, and all apartments have an individual parking space in the underground garages as well as a store room. The underground garages can be reached by soundproofed automatic lifts.

Colinas de la Duquesa is being built just above La Duquesa Golf and Country Club on the brow of Loma del Hacho, or Beacon Hill, a high point ensuring marvellous views over the golf course, the surrounding countryside and the mountains beyond.
