Buildner has revealed the winners of the Architect’s Stair competition, inviting a reimagining of one of architecture’s timeless forms. Participants explored adaptive stairs not merely as connectors, but as expressive structures that narrate architectural stories through design.
Creators were tasked with conceptualizing these steps as poetic artifacts rather than mere technical solutions, allowing designers to redefine them within sculptural and philosophical contexts. They embraced historical references, cultural symbolism, and bold new visions, with stairways becoming experimental spaces that blend function with fiction.
A jury of leading architects evaluated submissions based on concept clarity, originality, and spatial creativity. Esteemed judges included Beste Aykut from BKSK Architects and Pippa Nissen from Nissen Richards Studio, among others. Alongside this competition, Buildner is also hosting The Oak Moon Pavilion and Museum of Emotions #9, inviting innovative ideas in different architectural domains.
