DAVIDSON RAFAILIDIS

NICOLAS DORVAL-BORY

Stephanie Davidson and Georg Rafailidis work together as DAVIDSON RAFAILIDIS, a collaborative focused on the complex relationships between architectural intent and lived reality.

Nicolas Dorval-Bory (1980) graduated from the ENSA Paris Val de Seine in 2007 and founded his practice in Paris in 2008.

After collaborations in Chile and Argentina (2009-2010), the office NICOLAS DORVALBORY ARCHITECTES operates today in a wide range of scales in France and abroad.

He has taught since 2011, notably alongside Philippe Rahm at ENSA Versailles, became a tenured Associate Professor in 2022, and served as Director of this school from January 2025 to March 2026. In 2016, he received the French AJAP award.

In 2022, he co-curated BAP!2 - Visible Invisible, the second Île-de-France Architecture and Landscape Biennial.

The duo met at the Architectural Association in London and now work across observation, documentation, and design.

Work of DAVIDSON RAFAILIDIS has been published and exhibited internationally, and both have taught in Canada, in the US, Germany, and Greece.

RAYMUND RYAN Raymund Ryan is Curatorat-Large at the Heinz Architectural Center, Carnegie Museum of Art, Pittsburgh.

Recent exhibitions in Pittsburgh include Building Optimism: Public Space in South America (2016), The Fabricated Landscape (2021), and Tatiana Bilbao Estudio: City of Rooms (2024).

A THREE-BODY PROBLEM It’s a simple house, almost astonishingly simple considering the conceptual strength it exudes. I discovered it somewhat by chance about ten years ago, most likely on an architecture blog. It was the first thing I encountered by Davidson Rafailidis, a fascinating duo whose work I would continue to follow closely – always precise, always questioning uses and ways of living, with a disarming simplicity and construction culture.

In this project, the first impression is a of a wide yet low window opening topped by a large, uniform roof, reminiscent of Kazuo Shinohara’s Tanikawa House. A curious, strangely familiar encounter in this suburban setting of Buffalo, in the far west of New York State. As the exterior unfolds: exposed timber framing in the awnings and skylights, still covered in that very neutral corrugated metal sheeting, but also galvanized steel structural elements clad in transparent polycarbonate, or black-painted wood siding.

Inside: plywood on floor, walls, ceiling, then large expanses of immaculate plasterboard, like an art gallery, alongside glazing and concrete floors. The materials and construction techniques are ordinary, yet there remains something unsettling in the way they are assembled. Looking through this photographic documentary, one quickly grasps a diversity and principles of spatial assemblage. This becomes clear when considering the plan and the project’s title, He, She, & It: a house as an aggregation of three worlds, each with its own needs, qualities, and materiality. Two identical rectangular volumes in plan, and a third square one distributing the other two. Three volumes of equivalent size, each with a shed roof, leaning against one another like a pinwheel. But beyond these three distinct spaces, each encounter with another part gives rise to unique spatial situations, adding to the intrinsic architectural qualities of each volume. New situations, multiplied through the interaction of these three inhabitants.

I often showed this house to my students in ÉNSA-Versailles, as part of my teaching on individual housing. Initially, for the aforementioned specific qualities of the project, but also to illustrate and explore the transmission of ideas in architecture and their evolution.

I liked presenting diptychs across time – approaches that respond to one another – such as Kazuo Shinohara with Pascal Flammer, or OM Ungers and Office KGDVS, Kiyonori Kikutake and Pezo von Ellrichshausen, Jan Szpacowicz and SANAA. I would then pair this Davidson Rafailidis project with Lacaton & Vassal. No value judgment here, no attempt to demonstrate lineage, which may be real but often exists only in my own interpretation. Rather, the persistence across eras of certain forms of space, certain ways of constructing rooms or assemblages, and qualities of emptiness seems to say a great deal about what architecture fundamentally is. Here, specifically, there is the simplicity of spaces, the search for neutrality – or rather the withdrawal of a symbolic meaning from architecture – a quest for a lower, weaker, and more fundamental level of construction. And there is the articulation of spaces that do, as radically as possible, what they are supposed to do. In the work of Lacaton & Vassal, this latter principle has often been explored in a particularly explicit way, through duality. From the paillotte in Niamey (a closed circular volume juxtaposed with a light square roof) to the FRAC Nord-Pas-de-Calais, and of course including the Latapie house (the house and its double – the greenhouse), Lacaton & Vassal frequently rely on a dialectical principle to construct space. Like a philosophical method founded on radical oppositions – a Hegelian, but also very French approach to thought – Lacaton & Vassal’s symmetry produces strongly defined spaces (thesis and antithesis), contrasts that bring forth – in the user’s movement between them – other unexpected architectural riches (synthesis).

Davidson Rafailidis take up these strategies, but carry them further, where Lacaton & Vassal could not have gone.

Indeed, while He, She & It adopts Lacaton & Vassal’s neutral vocabulary, combined with the simplicity and ordinariness of a timber-frame construction, the project is not binary, or a diptych, but rather a triptych, in which the three situations respond to one another. We thus move beyond dialectics, based on opposition, to a relational subtlety grounded in complementarity and difference. This may seem trivial, but shifting from two to three, from symmetry to diversity, produces a fundamentally different movement in what the project reveals about its contemporaneity.

In astrophysics, there is a particularly relevant analogy for understanding this issue.

The “two-body problem” describes the way the interaction between two stars or celestial bodies can be calculated (typically the Earth orbiting the Sun). It was solved in the 18th century by Isaac Newton through Kepler’s equations, and is commonly used in physical science. By contrast, the mere addition of at least one more body – the “three-body problem” (or “N-body problem”) – introduces a form of chaos into the equations, something fundamentally irresolvable. This impossibility continues to provoke profound questioning among mathematicians and physicists, and teaches us that the relationship between three objects is infinitely richer and more complex than the frontal opposition of two. In He, She & It, this triptych composition, through its openness to a third user – vegetal, moreover – allows us to imagine this infinity of interactions, and the resulting symbiosis between occupants. Materialized in architecture, the threebody problem of Davidson Rafailidis does not seek a solution, but embraces the infinity of possibilities between humans and their environment.
