Inside, the functions of the new JRC building are organized with public program and amenities such as dining, a conference center and social spaces on the ground floor, while the offices and research units occupy the upper floors for privacy and security. The collaborative workplaces face the plaza, while the deep-focus workspaces face the garden. The proposed layout is designed to be entirely flexible and adaptable according to any future needs of the JRC.

When asked to design an apartment block next to a parking garage, BIG saw an opportunity to explore a new form of symbiotic urbanism. Rather than placing a traditional slab of apartments next to a block of cars, BIG proposed mixing the two and exploiting their differences as a strength rather than a weakness: cars need large floor plates and good proximity to the street, while houses want sunlight and views. As a result, the parking is turned into a podium for the building&#;s homes that form a stepping landscape of houses with gardens.

The building’s tallest corner is lifted up to m in order to maximize the inflow of natural daylight as well as views towards Gärdet and the Frihamnen port for most of its units. The modules cascade down to the building’s lowest profile at just m, gradually extending the wooden development into the park. &Park appears like a gentle hillside, seamlessly blending into the nature around it.

The building includes flexible workspaces with a full-height perimeter glazed-façade – maximizing daylight and offering panoramic views towards historic landmarks such as World Heritage St Paul’s Cathedral, Old Bailey, St Brides and the Royal Courts of Justice. Fleet Street embeds strong environmental credentials geared to meet the benchmarks set out by Whole Life Carbon and Circular Economy principles to reduce the embodied carbon of the development.

The building comprised of timber in its upper structures, bridges and slabs features a long and slim footprint covering an area of ca. , m. SBC makes full use of the allowed maximum building height of . m across seven floors, and is based on an ideal office bar typology measuring m in width. Instead of one single zig-zag volume, as envisioned in the masterplan, BIG’s design consists of two stacked and rotated zig-zagging bars.
