Circular Daycare Centre near Copenhagen

 - Peter Popp

The Svanen daycare centre in Gladsaxe north of Copenhagen is exemplary in terms of its radically sustainable approach to contemporary educational architecture. The designers from Lendager transformed an abandoned school building into a childproof and visually manifold ensemble – based on the maximum degree of reuse of on-site construction materials.

Instead of simply demolishing the school complex that had been vacant for a number of years and replacing it with a conventional new structure, the decision was made for a circular and process-oriented approach. A feasibility study authored cooperatively by the municipality and the planners concluded that the dilapidated building fabric from the 1930s and 1960s wasn’t suitable for conversion – however, it was adequate for nearly complete upcycling on the same site. The principle of “form follows availability” guided Lendager in their design for the new facility. It employs the existing materials as its structural, functional, and atmospheric design basis. Roughly 6000 tons of concrete, 12 000 roof tiles, 80 000 masonry bricks, as well as numerous steel and timber elements were reclaimed, catalogued, and processed. This meticulous approach led to a logistical challenge, yet also evolved into the core of the design method. Materials were, in part, stored on site on the former school sports field. This allowed avoiding long transport routes and became a factor that significantly influenced the ecobalance.

The daycare centre is situated in a former industrial zone that was eventually transformed into a mixed use district. The additive geometry is a response to the heterogeneous context. The U-shape of the floor plan is oriented on the children’s everyday life in terms of its dimensions and scale. Single storey building volumes with pitched roofs and parallel gables surround a protected interior courtyard. The facade materials alternate, comprising masonry brick, corrugated sheet metal, horizontal wood siding, and red roofing tile. The resulting impression echoes the image of an unplanned, idyllic village – a spatial collage that enables both comprehension and sensual experience. On the inside, the houses are interconnected. The central meeting point of the integrative facility for altogether 148 children is a glazed orangery. Its construction refers directly to the previous building. The six original wood trusses that support the glazed roof were sourced from the former gymnasium. They were structurally retrofit by use of additional timber elements, steel plates, and tension rods. The orangery also serves as entrance and foyer. From here, the daycare centre branches out into the two lateral wings comprising four group rooms each, in addition to shared zones and sanitary spaces. The gymnastics area across from the orangery was designed for children with disabilities. The entire facility is barrier-free.

The daycare centre interiors predominantly feature bright coloured, natural materials. The open spaces reach up to the underside of the pitched roofs, where lightweight wood wool panels balance the interior acoustics. Solid timber surfaces establish a warm and cozy atmosphere. All materials used on the inside of the building are emission-free and C2C certified. This supported saving resources during construction as well as creating a healthy indoor climate. As a result, the daycare centre was awarded the Nordic Swan Ecolabel.

  • Paul Van Ostaijen Culture Campus in Leuven

    Lava architecten transformed an old mission building in Leuven into a place where circus arts, music, theatre, and dance coexist under one shared roof. Effective soundproofing is the precondition for the shared use of the facility.

  • The Lost Shtetl Museum in Lithuania

    The Jewish Museum in Šeduva commemorates the culture of Eastern European towns before World War II. With their building, Lahdelma & Mahlamäki Architects from Finland reimagine the small-scale structure of one such village. Its residents were murdered in 1941 by Nazis and their local collaborators.

  • Resembling a bridge, the scaly armour of the UCCA Clay Museum spans across the passageways to the neighbouring buildings. Where this structure touches the ground, Kengo Kuma & Associates arranged shallow water basins.

    Museum of Ceramic Art in Yixing

    The new UCCA Clay Museum advances the millennia-old tradition of artisanal ceramics the Chinese metropolis Yixing is renowned for. An armour of red clay tile encloses the exhibition spaces and the open timber roof constructions above them – an expressive space for the presentation of modern ceramic art.

  • The fly tower of the Glasshouse Theatre consists of textured prefabricated concrete elements, while the ­existing QPAC displays smooth in-situ concrete. The continuity of colouration, however, is clearly visible.

    Glasshouse Theatre in Brisbane

    The Glasshouse Theatre adds a fifth venue to the heritage-listed Queensland Performing Arts Centre. It can be flexibly used for concerts, operas, and dance and theatre performances. The glass facades of the deeply cantilevered foyer visualise the theatrical art of illusion on the exterior.

  • The monastery originally comprised four wings and a cloister. In the south, a squat church with a single nave connects to the complex. The head building with its three apses, a bell tower, and a transept were added in the 13th century.

    Monastery of Santa María of Sijena

    In their restoration of the Monastery of Santa María of Sijena, Pemán y Franco and Sebastián preserve traces of destruction, rebuilding, and decay spanning 800 years. Recently, they remodelled the east and north wings into an exhibition space for the convent’s valuable artworks.

  • The medical facility features a separate entrance in the east. A pergola made of prefabricated concrete elements welcomes the clients.

    Overnight Shelter and Medical Facility in Munich

    Housing for the homeless often consists of stacked contain ers. While the overnight shelter designed by Hild und K utilises prefabrication, thoughtful details adorn the robust building through which the Munich-based office conveys impres sions of warmth and home.
