What the Object Knows

The debut of Salone Raritas and the collectible design market's arrival at the centre of luxury living.

The Fair Rewrites Itself

For 63 years, the world's greatest furniture fair organized itself around a logic of industrial scale: the vast pavilions of Fiera Milano Rho, the brand stands, the product launches, the commercial machinery of a market that shapes how interiors are furnished across every price point and continent. The collectible object, the one-off, the limited edition piece from a gallery in Brussels or a studio in Cape Town, existed mostly in the surrounding city. It was the counterprogram. It was Fuorisalone.

That boundary dissolved on November 11, 2025, when Salone del Mobile announced Salone Raritas: the first dedicated exhibition within the fair for unique and limited-edition design, collectible objects, design antiques, and what the organizers call, with precision, 'outsider pieces.' The exhibition will occupy Pavilions 9-11 at Fiera Milano Rho, April 21-26, 2026. It will be curated by Annalisa Rosso, the Salone's editorial director, and its scenography is designed by Andrea Trimarchi and Simone Farresin of Formafantasma.

This is not a side room. It is a structural argument about where value now lives in the design world.

 

Formafantasma: The Architecture of Rarity

The choice of Formafantasma to design the exhibition space is not incidental. The Milan and Rotterdam-based studio, founded in 2009 by Trimarchi and Farresin, has spent fifteen years building a body of work that treats material culture as a form of critical thought. Their exhibitions for the Vitra Design Museum, their Prada Frames symposia, their Staging Modernity performance for Cassina during Milan Design Week 2025 where they staged a theatrical encounter between modernism and ecology, all of these have positioned Formafantasma as a studio that understands the politics and poetics of how objects are presented.

For Salone Raritas, they have conceived what they describe as a 'legible and permeable architectural landscape, a lantern that puts light and rhythm at the service of the pieces.' The space is organized not as traditional stands but as modular islands, each customizable within a defined palette of colors and materials. A central lounge anchors the commercial logic: it is designed for meetings, negotiations, and the kind of conversation that happens when a developer, an interior architect, and a gallery director are finally in the same room.

'They will not be booths,' said Simone Farresin at the London launch. 'The modular, respectful design allows each gallery to express its own identity while maintaining a choral narrative, designed for both visitor memorability and for market effectiveness.' This is exhibition design as cultural diplomacy.

The Market Signal

To understand why Salone Raritas matters beyond the programming, it is worth looking at the market conditions that made it necessary. The global luxury interior design market is on a trajectory that makes the early 2010s feel like a warm-up. Multiple research bodies currently project the market growing from approximately $136.7 billion in 2025 to between $155 billion and $190 billion by the early 2030s, at compound growth rates of between 5% and 7% per year.

Within that larger market, collectible design has become a distinct and accelerating segment. The evidence is not abstract: auction houses are reporting sustained growth in design results; galleries such as Carpenters Workshop, Galerie Kreo, Friedman Benda, and Southern Guild have expanded their programs and fairs significantly; and new platforms for collectible design have multiplied across cities, from Collectible in Brussels (with its 2024 New York debut) to Salon Art and Design expanding from New York to Dallas and beyond. Design Miami extended to Paris in 2023 and has since grown into Seoul and Los Angeles.

What all of these movements share is a recognition that the one-off object, the piece with authorial intent, research backing, and material intelligence, is no longer the province of a small collector community. It has entered the commercial vocabulary of luxury hospitality, branded residential development, and high-end retail. The question for developers, hoteliers, and their design teams is no longer whether to incorporate collectible design. It is how to source it, curate it, and build coherent narratives around it.

Salone Raritas exists because the professional design market, the B2B world of architects, interior designers, developers, and contractors, has arrived at precisely that question.

 

What Changes and What It Means for Spaces

The integration of collectible objects into luxury residential and hospitality interiors is not new. What is new is its systematization. Maria Porro, president of Salone del Mobile, described Raritas as a 'direct interface between collectible design, antiques, and high-end craftsmanship on the one hand, and the contemporary B2B market on the other.' The language is revealing: she is not describing a cultural enrichment program. She is describing a supply chain.

For the architects and interior designers who specify objects for high-net-worth clients, this represents a significant shift in procurement logic. Collectible design, until now accessed primarily through gallery relationships, fair circuits, and personal networks, gains a new institutional channel. For the developers who want to position a residential building or boutique hotel around a coherent design identity, it offers the possibility of sourcing the rare objects that anchor such an identity through a platform they already attend.

The implications for spatial quality are real. A room where one or two objects carry genuine authorial weight, where something was made by a known hand, limited in number, and chosen with intelligence, reads differently from a room where everything has been specified from a catalogue, however beautiful that catalogue may be. Rarity, when it is earned by craft and research rather than manufactured by artificial scarcity, functions as a form of spatial argument. It tells the person standing in the room that someone thought hard about what belongs here, and why.

This is the distinction that EFC Group has always understood. It is the distinction that Salone Raritas is now making structural.

The Collectible as Identity Infrastructure

What Salone Raritas ultimately articulates is a concept that the most sophisticated design clients have long intuited but that the market is only now formalizing: the collectible object is not a finishing touch applied to an otherwise complete interior. It is identity infrastructure. It is the material evidence of a point of view.

For a residence, it is the difference between a space that looks expensive and a space that looks educated. For a hotel, it is the difference between a property that has been decorated and one that has been curated. For a developer, it is the difference between a luxury offering and a cultural proposition. These distinctions are not subtle to the people who inhabit and experience these spaces. They are the primary language through which the built environment communicates its values.

The roughly 25 galleries of excellence that will participate in Salone Raritas's inaugural edition bring with them the breadth and depth of the international collectible design world: contemporary makers alongside rare design antiques, limited series alongside one-of-a-kind prototypes, high-end creative craftsmanship alongside the outsider pieces that exist at the boundary between design and art. What Formafantasma's architectural lantern does is hold all of this within a single coherent field, legible to the professional visitor who may be encountering much of it for the first time.

The collectible has entered the fair. The object has claimed its place at the centre of the conversation. The question for those who build, curate, and inhabit exceptional spaces is what they intend to do about it.

For the first time, unique and research pieces, limited editions, and high-end creative craftsmanship fully enter the heart of the Salone. Welcoming and enhancing these pieces means recognizing the value of design conceived to last over time." Maria Porro, President, Salone del Mobile.Milano.

What We Believe About This Moment

What Not A Hotel Setouchi demonstrates, with unusual clarity, is that the decision about material is a philosophical decision before it is an aesthetic one. When Bjarke Ingels and his team chose to make the load-bearing walls of these villas from the island's own soil, they committed to a position: that the building's integrity would come from its relationship to its place, not from its relationship to any catalogue of approved finishes. That commitment changes everything that follows. The proportions, the views, the quality of light on the curved earthen wall -- all of it is made possible by the first decision, the one about where the material comes from. EFC Group has always believed this is how exceptional spaces are built: not from the outside in, with materials and objects added to a completed frame, but from the ground up, with every element earning its place through an argument about what belongs here.

The Not A Hotel model adds a dimension to this that is worth understanding carefully. The fractional ownership structure means that the architectural proposition must be strong enough to justify return -- to bring its owners back not out of obligation but out of genuine desire for the specific experience the place offers. That is an extraordinarily high standard for a building to meet. It means the architecture cannot be merely impressive; it must be irreplaceable. The rammed earth walls of Setouchi are irreplaceable by definition: they are made from the soil of a specific island, at a specific time, in a specific climate. No other property in the network will ever share their material identity. That singularity is the ownership model's deepest asset, and the architecture's finest achievement.

For EFC Group and the clients we work with, this is the question every significant design decision should be answerable to: does this belong here, or is it merely excellent? The two categories are not the same. Excellence can be sourced from anywhere. Belonging requires knowledge -- of the site, of the material, of the cultural and physical context that makes this place different from every other. When Ella Fontanals-Cisneros built the spaces she built and assembled the collection she assembled, the consistency was never stylistic. It was curatorial: a point of view exercised over time, in specific places, with material and objects that carry genuine history. That is the standard Not A Hotel Setouchi holds itself to, and the standard this moment in architecture is demanding.

EXECUTIVE SUMMARY

Not A Hotel Setouchi, designed by Bjarke Ingels Group and opened to fractional owners on April 1, 2026, marks BIG's first completed buildings in Japan -- three rammed-earth villas on the remote island of Sagishima in the Seto Inland Sea, organized around panoramic views of 360, 270, and 180 degrees. The walls are made from soil excavated on-site, making each building structurally inseparable from its landscape. The project arrives during a decisive revival of earthen construction across luxury, cultural, and residential architecture globally, with rammed earth demonstrating a tenfold reduction in embodied carbon versus concrete while producing a spatial quality that no industrial material replicates. Not A Hotel's fractional ownership model -- which allows owners to trade nights across a network of architect-designed properties including projects by Jean Nouvel and Zaha Hadid Architects -- adds a commercial dimension to the architectural argument: a property must be irreplaceable, not merely excellent, to sustain its proposition. For EFC Group and its clients, Not A Hotel Setouchi is the clearest current example of what it looks like when material conviction, site intelligence, and ownership logic converge into a single architectural position.
