At Goodbye2000, we view each new build project in Altea as an opportunity to create a home that combines design, functionality and the unique charm of this Mediterranean town. From the initial study of the plot and the definition of the architectural concept to the management of licences and construction supervision, we accompany our clients throughout the entire process with a friendly and professional approach.
We design contemporary homes that respect the essence of Altea, integrating Mediterranean style with innovative solutions. Our projects take advantage of natural light, open sea views and the uniqueness of the old town and its surroundings, seeking a balance between modernity, sustainability and tradition.
For Goodbye2000, architecture in Altea is not limited to building walls: it is about creating spaces with soul, designed to last, reflect the personality of each client and form part of the architectural identity of the Costa Blanca.
Renovations in Altea
At Goodbye2000, we view every renovation in Altea as an opportunity to reinterpret a home and adapt it to a contemporary lifestyle without losing its Mediterranean essence. We carefully study the existing structure, layout and materials to come up with solutions that bring harmony, comfort and added value.
Our projects take advantage of Altea’s characteristic light, its sea views and the surroundings of the old town, improving energy efficiency and modernising each space. We take care of the entire process in a comprehensive manner: from the initial design and selection of materials to the execution of the work, ensuring a result that is faithful to the project and respectful of the environment.
Shopping and experiences in Altea
At Goodbye2000, we work alongside companies and entrepreneurs in Altea to design commercial premises, offices and restaurant spaces that convey each brand’s identity and create memorable experiences. Our approach integrates architecture, interior design and brand strategy to create environments that connect with customers and reinforce the personality of the business.
Each project is tailor-made: from the renovation of a boutique in the streets of Altea’s old town to the creation of a gastronomic space overlooking the Mediterranean. We are committed to sustainable materials and innovative construction solutions that make each space modern, efficient and unique.


Javier Pérez Puchalt
Javier Pérez Puchalt, co-founder of Goodbye2000, is a committed and rigorous architect, creative and with great project management skills.
He graduated from the Swiss Federal Institute of Technology in Lausanne (Switzerland) in 2017 and holds a PhD in Architecture from the University of Bologna in Italy and the Catholic University of Louvain-La-Neuve in Belgium (2024).

Sergio Espinosa Pérez
Sergio Espinosa Pérez has a natural sensitivity for art, design, trends and details.
He graduated from the Valencia School of Art and Design (EASD) as an interior designer.
Since the beginning of his studies, design has been his way of expressing his passion for aesthetics. His greatest inspiration is everything around him, and through his observation, he approaches each project by thinking through and conceiving even the smallest details. After several years of working with different design teams, he decided to continue learning and broaden his creative horizons.
He studied a Master’s Degree in Art Direction: Film, TV and Performing Arts at Barreira Arte + Diseño, where he came into contact with the world of audiovisual production, thus broadening his vision. Together with Javier, he founded Goodbye2000 in 2023.

Study
Goodbye2000 was born from the collaboration between Sergio and Javier, two young creators who, through our work as a designer and architect, promote and share our own unique way of understanding life.
Our approach to work consists of addressing the needs presented to us with empathy and absolute honesty, with originality and freshness.
Over the years, we have jointly built a world of references that form the basis of the work we do at Goodbye2000.
We contribute our experience and artistic background, always reinterpreting what we already know and what already exists, thus offering solutions with maximum added value, where the functional and the artistic coexist.
Our success lies in improving our clients’ quality of life by offering projects that always stem from constant listening and dialogue with them.
