Bob Tower Jr.

Bob Tower Jr. is a housing project located in La Paz, Bolivia. It consists of a total of 16 apartments with an average floor space of 61 square meters. Bob Tower Jr. was developed by Bob Constructores, a local real estate development company with a focus on creating innovative, sustainable construction projects.

By incorporating modern construction technologies such as reflective paint and insulation on roofs and external walls, low-E coated glass, the use of energy-saving appliances such as refrigerators and washing machines and LED lightbulbs as well as water-efficient plumbing features, the project was able to significantly reduce its energy and water consumption, resulting in a more sustainable construction project and a reduced carbon footprint.
