Commercial Infrastructure And Training


Balsells Group is a group of companies that provides an end-to-end service for the real estate industry.

We have been closely linked to this industry for more than forty years, always working with passion and professionalism.

The speciality of each one of the Grupo Balsells companies and their constant synergies give us in-depth knowledge of the market and of business opportunities, while keeping us abreast of the latest legislative and fiscal developments. We provide services ranging from the purchase, sale or rental of properties, including tourist apartments, to insurance or building management.

In 1980, Ramon Balsells and Marià Zaragoza channelled their experience into a single business and founded Balsells Zaragoza Gestió, an insurance broker and building management firm. The offices were located on Calle Cartagena in Barcelona.

Little by little, responding to the needs of their clients, they went into the business of renting apartments, rental management and real estate sales.

In 2009, Ramon Balsells Sagrera joined the company and realised that boosting the estate agency side would modernise the company and make it grow even further.
To expand this line of business, he studied all the possibilities and chose the best option: to open a franchise of Century 21, an American sales and rentals company present in 80 countries and with more than 80,000 offices, which boasts a proven and very successful work system that ensures excellence in service and customer care through a sales network of independent estate agents.

This gave birth to Century 21 BZ Gestió, the sales and purchase branch of Grupo Balsells Zaragoza, which currently has twenty-one agents.

Century 21 BZ Gestió then bought Century 21 Xarxa, another office located on Calle Girona, which was and still is the number one for sales in the whole of Catalonia. And so the Balsells Group Zaragoza kept on growing.

In the past few years, the course of the industry and our privileged location in Barcelona’s Eixample district encouraged us to expand our vision, so we decided to open another line of business within Balsells Zaragoza Gestió, BBarcelona apartments, to manage licensed tourist apartments.
