Gamperstrasse extension . Zurich

A harmonious blend of modernity and history

The Gamperstrasse extension in Zurich, designed by Baukombinat, represents a thoughtful evolution of a historic row building originally constructed in 1894. The northernmost section of the original structure has long been compromised by the encroaching railway tracks, and now, with the extension of Lagerstrasse, the middle section will follow suit. This transformation ensures that the newly extended building remains a significant urban landmark within the perimeter block quarter.

The design approach for the extension intertwines the new volume with the existing structure, creating a seamless architectural dialogue across the eave line. This careful balance of symmetries enhances the main facade's prominence on the street side while allowing for a more liberated arrangement of openings towards the courtyard. This design strategy not only enriches the building's aesthetics but also enhances the quality of the outdoor spaces.

The project introduces two compact five-room maisonette apartments, tailored for shared living and families, complementing the classic three-room apartments typical of the Wilhelminian style found in the existing building. Remarkably, the extension was completed while the building remained fully occupied, showcasing a commitment to maintaining residents' comfort throughout the construction process.

Floor plans leverage the structural possibilities of the original building, revealing surprising vertical and diagonal spatial relationships despite their apparent simplicity. The flow from entrance to kitchen, dining, and living areas culminates in more private bedrooms, enhanced by a versatile room whose double-leaf door opens into the living space, creating a dynamic interaction between areas.

Residents benefit from outdoor spaces across three levels, which not only foster internal connections but also frame views of the surrounding urban landscape and distant horizons. The wooden construction, characterized by solid panels and ceilings, is meticulously designed, ensuring durability and repairability while harmonizing with the precise spatial roles of elements such as doors and kitchens.
