SHARE Bulgaria 2023 will provide attendees with access to knowledge and new opportunities for collaboration. National and international renowned speakers, and innovators in architecture and building technologies will provide the audience with insightful technical details of large-scale projects as well as inspirational visions.



MEET THE GUEST | Stefano Capranico,  Senior Associate Design Architect UNStudio

Stefano Capranico, a graduate of the Turin Polytechnic Faculty of Architecture in 2007, has amassed a remarkable career in the field of architecture and design. His journey led him to join UNStudio in 2015 after serving as the Head of Architecture and Interior Design at Pininfarina.

During his tenure at Pininfarina, Stefano played a pivotal role in leading the design of prestigious projects such as the Juventus Stadium in Turin, the Cyrela Tower in São Paulo, and Ferra in Singapore.

At UNStudio, he continued his professional flourishment by contributing to multiple winning teams for international competitions, including the Überseequartier in Hamburg, a confidential headquarters in San Francisco, and most notably, FOUR Frankfurt, a sprawling 220,000 sqm development at the heart of the city.

Frankfurt FOUR

At the very core of Frankfurt, on a site that has been inaccessible for the last 45 years, four new high-rise towers will change Frankfurt’s skyline from the air, while cultivating its liveliness on the ground. The development of these towers, reaching heights of 228 meters, will open up new streets to create a multi-use, vibrant inner-city quarter, bringing together a healthy mix of work, living, relaxation and recreation. The four towers are grouped in such a way that the central square is completely framed. The differentiation of the orientation and heights of the four high-rise buildings articulates variations within the skyline and optimizes daylight penetration.

At the same time, a sustainable, open, lively and socially balanced quarter is growing – with 600 apartments in various sizes, and partly as subsidized living space, with high-quality office space, hotels and urban flair. Gastronomy, retail, city squares, a public roof terrace and green islands enliven the quarter. New access routes connect it with the city center and the banking district. FOUR is the new face of the city – in direct proximity to sun, clouds, wind and weather.

From the outside, the site opens up towards the city center, creating a new urban quarter. New connecting routes, passages and squares will enliven the area and connect it to the pedestrian zones in the city centre. Publicly accessible spaces, such as a planned roof garden, a city square, multiple restaurants and retail outlets aim to improve the quality of time spent in the financial district. The consistent opening-up of the city quarter ensures a new network of the inner city routes between the banking district, the Rossmarkt, the Kaiserplatz and the shopping areas of the Goethestraße as far as the Old Opera House. Campus

One of the largest urban projects in Western Europe, the campus is a lively environment where people can meet, inspire, live, work and play. Through mixed-use facilities designed with a holistic approach to health and wellbeing, the campus creates a positive experience for all users: from the citizens of Amsterdam who use the public space and retail facilities, to the tenants who live in the residential building, to the young workforce.

The UNStudio’s all-inclusive approach to health encompassed 10 factors that address the differing needs of occupants while also achieving a BREEAM Excellent design certificate. These 10 factors include a considered approach to air circulation, water, nourishment, daylight, physical movement, thermal comfort, sound and materials, as well as a holistic approach to mental wellbeing, and strategies to give back to the Amsterdam community.



Throughout the building, the architecture nudges employees to move by fostering engaging environments and by encouraging physical movement across all levels. Underfloor air distribution is used to provide fresh air in close proximity to the users, while radiant ceilings allow for very comfortable heating and cooling. Special attention has also been given to the acoustics in both the office spaces and the atria, while alongside the generous daylight throughout the building, high-quality artificial light with very low glare enhances visual comfort.
