  • In 2021, a remarkable milestone in our story unfolded through a Joint Venture with a Stockholm-based real estate agency, forming Bremberg International. This strategic alliance led to the inauguration of a splendid new office in Marbella, further enhancing our presence and reach in the ever-thriving property landscape.
  • True to our spirit of expansion and commitment to exceptional service, the year 2023 marked the birth of G-Estates. Our vision extended beyond conventional horizons, encompassing comprehensive property investment advisory services. This includes bespoke holiday rental management, legal expertise, and top-notch interior design services, tailored to cater to the diverse needs of our clientele.
  • At the core of our operations, we embrace cutting-edge AI tools to bolster our capabilities. Collaborating closely with our esteemed international partners across Europe and Asia, we epitomize the role of a local expert when it comes to astute property investment.
  • However, our journey into the future extends beyond mere technological advancements. We envision a harmonious blend of the digital realm with the human touch. As we forge ahead in the proptech direction, we pride ourselves on maintaining a highly digitalized workflow, all while cherishing the essential human aspect that underpins the art of investing in Spanish coastal properties.
  • At every step of the way, we are committed to ensuring that our clients' aspirations find their perfect match in the realm of real estate, on the sun-kissed shores of Spain.
