At American University of Sharjah (AUS), our research has been investigating this. Using computational modelling, we have studied how dune sand naturally accumulates, erodes and self-organises under wind and gravity, and how those same patterns can be translated, through digital fabrication and 3D printing, into new architectural systems. Other AUS projects have explored locally sourced materials and “material ecologies” designed to cut waste and strengthen the relationship between buildings and the environments that surround them.

This is not an argument for trading concrete towers for mud-brick ones, nor for romanticising the architecture of the past. Traditional Gulf building, with its  thick walls, shaded courtyards, thermal mass and carefully oriented openings, emerged from a deep understanding of climate and material constraints long before mechanical cooling existed. That knowledge still matters. But simply reviving historical earthen techniques is not a realistic answer for a region where sand is abundant but suitable clay is comparatively scarce. The opportunity instead lies in asking a different question: what new forms of architecture can emerge when we start with the materials that are actually abundant here?

Discussions about the future of cities tend to focus on artificial intelligence, smart infrastructure and digital systems. These matter. But resilience is also a material question. A genuinely intelligent city has to consider not only how buildings operate, but what they are made from and how those materials relate to local conditions. Dune formations, erosion patterns and sedimentary processes are not random; they are physical records of an ongoing negotiation between wind, gravity, climate and time. Reading and applying that intelligence, rather than treating sand as merely a problem to stabilise, is the real design challenge.

This thinking is gaining ground. The recent TURAB Prize, a regional award recognising innovation in earth-based construction, highlighted projects examining sustainability and material stewardship. Two first-place entries came from AUS, both reinterpreting regional material knowledge through digital fabrication rather than looking backward. This reflects a broader shift in the profession: the most promising solutions are emerging not from choosing between tradition and technology, but from combining them.

Critics sometimes dismiss earth-based materials as nostalgic or impractical for contemporary cities. They are right that sand and earth alone will not build the future of Dubai, Abu Dhabi or Sharjah. But that misses the point. The question is not whether alternative materials can fully replace concrete and steel. They can’t, not yet and perhaps not ever at scale. It is whether building material systems that are better adapted to local conditions, and sourced locally, can reduce dependence on carbon-intensive construction. Even incremental shifts in sourcing, fabrication and deployment add up across a rapidly urbanising region.

Realizing that will take more than research papers and prize shortlists. It will take developers willing to pilot sand-based components at building scale, and regulators and funders willing to back that experimentation alongside the smart-infrastructure investment the UAE already prioritises. The technical groundwork, computational modelling, robotic fabrication and additive manufacturing, already exists. What is needed next is to treat material innovation with the same urgency as digital innovation.

The UAE is well placed to lead this. Few places combine such demanding environmental conditions with such ambitious investment in technological innovation, or such a rich legacy of climate-responsive design. Architecture’s role here extends beyond energy efficiency or certification. It is an opportunity to rethink the relationship between the built and the natural, so that buildings emerge from an understanding of the desert’s materials and processes rather than being imposed upon them.

The Gulf should not merely adapt to the desert. It should learn from it,not as heritage, but as foundation.

The future of Gulf architecture could be written in sand, not concrete.
