The Vilharia

In June 2026, Vilharia, a commercial building located in Ljubljana, Slovenia, achieved a significant milestone by obtaining its use permit. This marks a crucial phase in the project's development and underscores its importance as a landmark structure in the country. Recognized as the most sustainable business building in Slovenia, Vilharia has already attracted attention from both local and international organizations seeking modern, environmentally friendly workspaces.

The building’s success is reflected in its current occupancy rate, which stands at 85 percent following the signing of recent lease agreements. The remaining 15 percent of office space remains available for potential tenants. Investors have noted that these partnerships go beyond mere office rental arrangements—they serve as evidence that international institutions and companies are actively seeking spaces that combine energy efficiency, high environmental standards, and adaptability to contemporary working styles.

Michal Maco, director of Corwin for Slovenia, emphasized the significance of this achievement. He highlighted how modern businesses compete not just on salary but also on employee comfort and flexibility. Vilharia, being unique in Slovenia, supports this need by offering adaptable work environments that promote well-being and productivity among employees. The building's LEED Platinum certification further reinforces its status as a model for future-oriented and sustainable work environments.

New tenants have joined Vilharia, contributing to its reputation and reflecting the quality it brings to the city. Among them is the European Agency for Cooperation of Energy Regulators (ACER), based in Ljubljana. As the sole EU agency in Slovenia, ACER plays a pivotal role in integrating energy markets across Europe. It promotes a unified electricity and gas market, ensures safe supply, sustainability, and strives for affordable prices, thereby enhancing the competitiveness and energy independence of the EU.

Another notable tenant is SAP, a leading global company in business applications and artificial intelligence. With advanced cloud solutions, SAP enables businesses to respond more effectively to dynamic market conditions while promoting innovation and sustainable growth. Its mission is to help companies achieve their full potential through responsible business practices and solutions that support sustainable business operations.

Additionally, Adriaplin, a subsidiary of the global energy group Plenitude and part of the Eni Group, has chosen Vilharia for its new offices. Adriaplin is one of the leading providers of natural gas on the Slovenian market, specializing in sales and distribution. Known for its professional and user-focused approach, Adriaplin has been providing safe and reliable energy solutions since 1994 for households, businesses, and industry.

Vilharia represents a vision for the future of urban development in Ljubljana. Corwin, a leading real estate developer in Central Europe, has brought a new definition of a high-quality work environment with Vilharia. The building integrates cutting-edge technology and sustainable responsibility, setting new standards for office spaces in Slovenia. Designed by the renowned Scandinavian architectural firm Schmidt Hammer Lassen, the building emphasizes light, access to outdoor areas, and everyday human experiences. Rather than isolating itself, Vilharia encourages social interaction and healthy lifestyles through its accessibility, sustainable design, and high level of comfort.

The building's design highlights the importance of creating environments that foster vitality within the city and set new benchmarks for office spaces in Slovenia. By focusing on sustainability, energy efficiency, and user experience, Vilharia aims to become a central hub for innovative and forward-thinking businesses.

Previously, Vilharia had faced some scrutiny regarding its handling of construction waste during inspections, prompting environmental checks. However, officials clarified that these issues were not severe enough to delay the issuance of the use permit. Despite these challenges, the project has moved forward successfully, demonstrating resilience and commitment to high standards.

As Vilharia continues to attract new tenants and solidify its position as a premier business destination, it serves as a beacon for sustainable development in Ljubljana. The building's achievements reflect broader trends towards eco-friendly infrastructure and the growing demand for flexible, health-conscious work environments. Looking ahead, the continued success of Vilharia could influence future developments in urban planning and corporate real estate strategies in Slovenia and beyond.
