Buildner has announced the results of its international architecture ideas competition, Architect's Stair, and the launch of its third edition.

The event invited designers to reflect on one of architecture's oldest and most symbolic elements: the stair. Beyond its functional role as a connector of levels, the stair was positioned here as a medium of architectural storytelling—an invitation to explore ideas of procession, sequence, space, and form.

For this first edition, participants were asked to conceptualize a stair not as a technical solution but as an expressive artifact—an embodiment of their design sensibility and architectural values. There were no constraints on site, scale, material, or program. Instead, designers were challenged to reimagine the stair as a sculptural, poetic, and even philosophical construct—one that could provoke, question, or elevate our understanding of vertical space.

Buildings must change faster than they were built to. Shifting tenant needs, tightening climate policies, and rising office vacancies expose the cost of static stock: waste, noise, downtime, and—in the worst case—stranded assets. The consequence is clear: buildings across typologies must be designed to adapt over time. The inaugural Adaptable Building Conference (ABC), taking place on January 22, 2026, at the Nieuwe Instituut in Rotterdam, brings the industry together to turn adaptability from principle into practice.

The VELUX Group is launching the next step in its Action Leadership agenda as an experiment to explore how existing buildings can better serve both people and planet. The experiment builds on decades of demonstration projects and research into healthy buildings, including Living Places, which achieved an ultra-low carbon footprint and first-class indoor climate in an affordable and accessible way. The next step shifts focus towards existing buildings, from new build to renovation—named Re:Living.

Re:Living is a forward-thinking experiment to reimagine renovation to be more than a technical upgrade, and instead as a holistic opportunity to improve human well-being, support biodiversity, and reduce environmental impact. It's part of VELUX's long-term commitment to lead the building industry toward healthier, more sustainable practices, driven by a belief that simply reducing harm is no longer enough.

Buildner has announced the results of its Kinderspace Edition #2 Competition and launched the third annual Kinderspace Edition #3 with an upcoming registration deadline of 26 November 2025. Following its inaugural launch, this annual international competition once again invited architects, designers, and educators to explore new possibilities for early childhood learning environments.

Participants were tasked with envisioning spaces that inspire discovery, foster imagination, and support the emotional and cognitive development of young children. The aim was to move beyond standardized classroom design and propose innovative, flexible, and nature-connected spaces that reflect a deeper understanding of how children interact with their surroundings.

In the pursuit of cleaner, safer public restrooms, hand dryers have long faced a unique challenge: how to effectively kill germs in fast-moving air. Traditional germicidal technologies—like UV lights and ionizers— struggle to deliver meaningful impact because they only have milliseconds to interact with airborne microbes. Cold plasma technology is emerging as a new contender that could redefine hygiene standards.
