LUMNIA Building | RISCO

The Lumnia Building is an office complex located in a new urban area, adjacent to Lisbon´s Oriente train station, designed from scratch by RISCO. Boasting a floor area of 30,000m2, the building comprises 20 autonomous office units, each with an average size of 1300 m2, which can be combined to meet the requirements of tenants. Additionally, there are two retail units at the ground level, with direct street access.

The building's unique morphology is defined by four volumes arranged around a central courtyard, with variable heights ranging from two to nine floors in a helical progression. Of these volumes, three are hollowed out at the ground level, creating a seamless relationship between the courtyard and surrounding urban spaces, including the gardens to the North and South, and the new Rua da Centieira to the East.

To maximize natural light in the workspace and minimize dependence on artificial lighting, the upper volumes have a fully glazed facade that is strategically shaded. A solution of vertical slats with a depth of 0.5m and a spacing of 1.5m was used to shade the building, and three-dimensional modelling tools were used to study shading at different times of the day and months of the year. The study led to variations in the geometry and rhythm of the slats, creating a building that presents different textures and tonalities depending on the observer's position and the incidence of sunlight.

The main atrium, a space of unusual proportions (13m in height by 9m in width by 41m in length), is the centerpiece of the building's interior, designed to welcome more than 2,000 daily visitors. It features a striking contrast between the metal and glass facade and the concrete wall designed by P06 studio.

The project includes two outdoor areas that complement the building's functional workspaces: the central courtyard, designed for meetings and socialization, and the third-floor roof terrace, facing south, with pergolas, climbers, and wooden benches designed for extended stays. Both spaces were designed by NPK landscape architects.

The Lumnia Building is certified with Gold level in the Leed and Well systems, complies with NZEB energy requirements, and captures over one million liters of rainwater annually for storage and use in watering the surrounding gardens.
