What does the future of architecture hold? How will tomorrow’s buildings look, feel, and interact with the existing human-made environment? Which innovations are primed to help us reduce the footprint of construction, improve liveability, and redefine our idea of and relationship to space?
These are the questions Architizer’s Vision Awards look to answer (or, at least offer some suggestions in lieu of concrete answers). Dedicated to the planned and unbuilt, which may or may not ever be, nominations represent one of our most unique human traits — the ability to imagine possibilities and impossibilities, to dream big and think well into unchartered territory.
Unbuilt architecture, whether it is planned for construction or destined to remain on “paper,” should be more present in a newscycle of press releases for recently constructed or newly opened buildings. Indeed, many of the ideas presented in such projects directly respond to emerging crises exacerbated by our continued reliance on 20th-century practice’s approaches and materiality. Meanwhile, the evolution of architectural visualization allows architects to develop their wildest ideas and to communicate their boldest visions with more clarity and urgency than ever before.

Many studios are looking to re-write the script with high tech innovations that simply would not have been possible in the recent past, or emphasize the urgent need to get back to traditional building styles that utilize natural resources and passive principles in a bid to bring down carbon emissions and other outputs with negative environmental impact. The Kyathos Mass Timber Basketball Arena proposal does both.
It’s fitting that we should look at this concept in spring 2025. The Osaka Expo recently opened in Japan and features the largest free-standing wooden structure ever built. The Grand Ring encases the event site and a section of its coastal waters with a circumference of 61,035 square meters (656,975 square feet). To us, it reflects what is possible when modern engineering meets one of the world’s most sustainable materials. Likewise, realizing a size previously unthinkable with wood, Alexander Kitriniaris’ KAAF I Kitriniaris Associates Architecture Firm‘s plans for this Greek sports stadium offer a new vision for the athletic facility typology.

Employing a composite timber load bearing system, the project — commissioned by Galatsi Municipality — comprises a main court, spectator stands, internal mezzanine and gallery running the perimeter, changing rooms for athletes and referees, toilets, offices, and auxiliary spaces. Its total surface area is 4,000 square meters (43, 055 square feet), all of which complement the location. Designed for the site of an older, smaller wooden gymnasium, which fails to meet modern standards and is scheduled for demolition, the aesthetics reflect the surrounding Mediterranean flora grove.
The name Kyathos refers to a type of painted pottery cup popularized in ancient Greece. The design of this was based on the petals of a milkweed belonging to the Euphorbia genus of plants. The countryside in this region is home to around forty such species, making the entire building an ode to indigenous nature and culture that has been here for millennia. When realized, it will stand in sharp contrast to the stereotype of arenas and stadiums most fans across the world have grown accustomed to, which often seem to have landed in situ, from another district if not planet.

Above the main court level, the building’s structure is composed entirely of engineered wood, including glue-laminated timber, cross-laminated timber, and plywood. A timber support frame wraps the indoor gymnasium in a precise 45-by-30-meter (148-by-98 foot) rectangular grid. The roof is formed by ten identical isostatic frames. Symmetrical in design, these triple-arched assemblies combine beams and posts, reinforced where necessary by discreet metal connectors and stiffeners. Overhead, a lightweight polymer roof — waterproof, UV-resistant, recyclable, and printable — ensures durable protection while minimizing weight. In the renderings, an elegant lattice-like pattern, calls attention to these delicate considerations.
At the heart of the design, the firm’s plans and visualizations emphasize, lies a bioclimatic structural shell (pictured below), conceived to provide constant shade while optimizing natural ventilation, daylighting, and passive cooling. Meanwhile, rainwater collected from the roof and shaped surfaces is reused for on-site irrigation, supporting the lush Mediterranean flora of the existing grove.

This year, Saudi Arabia has begun working towards the World Cup 2034. Set to be held in November that year due to the incompatibility of regional climate and international football — or football at any level — the environmental price tag for this edition of the planet’s biggest soccer tournament is likely to be huge. While recent years have seen major strides taken to improve the impact of competitive sports, with last year’s Paris Olympics achieving more than 50% carbon reduction compared with the previous two Games, there are clear differences in what’s needed to host matches in cities like Jeddah and Riyadh. Not to mention the ultra-futurist urban experiment, NEOM — a metropolis that doesn’t exist yet.
Even during winter months, average temperatures across the desert state sit at a very hot 29°C. Humidity is high in coastal areas, while frost and snow are not uncommon overnight on higher ground. While it’s too early to tell the footprint of the vast mega-stadiums we’ve been promised for the competition, heating and cooling requirements are almost certainly going to be immense. We are, after all, experiencing a surge in global temperatures year-on-year and an increase in weather extremes of all kinds, and this will have significantly worsened in another ten years. More so, whether we’re powered with renewables or dinosaur fossils, high energy consumption of all types is not sustainable in the real sense.

Analyzing the legitimacy, authenticity and suitability of Saudi Arabia as a World Cup host nation is a conversation for another time. Perhaps another publication. But the fundamental point is we urgently need to rethink and reprioritize non-essential undertakings for the sake of the climate and our planet. When seen through this lens, the plans for Kyathos in Greece act as a symbol of progress and sets benchmarks for a future in which we acknowledge the need for our passions to be in balance with the Earth, rather imposing upon it. The fact this is achieved through an homage to a history in which we were more aligned to nature, and associated materials, but also utilizes modern engineering techniques and manufacturing methods of those materials, only accentuates the masterful vision behind this design.
Given the number of projects that will be designed between now and the stadium’s project 2028 construction date, and the ever-increasing concentration of carbon in our atmosphere, its urgent that we begin celebrating such plans now — while they’re still plans — rather than waiting for the design to become a physical building. After all, architecture starts before you put two bricks together (or, in this case, two pieces of timber).
