FLORIANÓPOLIS, BRAZIL — In an era where urban real estate is increasingly characterized by hyper-individualism, speculative density, and disconnected suburban sprawl, architectural innovation often emerges from the simplest of human desires: friendship and shared purpose. This is the foundational narrative behind the Campeche Houses (Casas Campeche), a striking residential project realized by the renowned São Paulo-based practice Terra e Tuma Arquitetos Associados.
Curated for public view by Susanna Moreira, the project captures the imagination of contemporary architects and urban planners alike. Situated on a single shared plot of land in Praia do Campeche—a vibrant, rapidly evolving coastal neighborhood on the southern coast of Florianópolis, Santa Catarina—the project addresses a deeply modern architectural puzzle: How can two independent households occupy the exact same footprint without sacrificing personal autonomy, while simultaneously fostering a sense of community, mutual support, and shared landscape?
Photographed masterfully by Débora Jank, the Campeche Houses stand as a testament to material honesty, spatial intelligence, and a nuanced understanding of tropical coastal living. Through a careful orchestration of concrete forms, private courtyards, and communal thresholds, Terra e Tuma has delivered a masterclass in co-housing that transcends standard multi-family typologies.
Main Facts: Architecture Born from Friendship and Pragmatism
The inception of the Campeche Houses was driven as much by personal connection as it was by financial and spatial pragmatism. Two close friends approached Terra e Tuma Arquitetos Associados with a unified vision: to relocate from their respective routines, build their dream homes, and establish a permanent foothold in the idyllic island setting of Florianópolis.
However, acquiring separate parcels of land in the highly sought-after Campeche district presented both economic and logistical hurdles. The solution was as pragmatic as it was symbolic: purchase a single, unified plot of land and co-develop it. This decision immediately set the parameters for the architectural challenge. The resulting design had to satisfy two distinct briefs—accommodating the individual lifestyles, aesthetic preferences, and spatial requirements of two separate households—while maintaining a cohesive architectural language that would not overwhelm the site or alienate the neighbors.

+-------------------------------------------------------------+Rather than splitting the lot down the middle with a harsh physical barrier or designing a monolithic duplex that forced the friends into an artificial proximity, the architects chose a more fluid approach. The design establishes a delicate equilibrium between separation and connection. Each residence operates as a fully autonomous entity, complete with its own living spaces, private zones, and operational independence. Yet, through clever site planning, the two structures converse with one another across shared courtyards, visual corridors, and transitional thresholds.
Chronology of the Project: From Concept to Coastal Reality
While architectural projects often move swiftly through digital rendering phases, the realization of the Campeche Houses required a meticulous, step-by-step evolution that respected both the local climate and the social dynamics of the two clients.
Phase 1: Conceptualization and Site Analysis
The project began with an extensive analysis of Praia do Campeche. Known for its strong winds, sandy soils, and humid subtropical climate, the coastal environment demanded a robust structural approach. Terra e Tuma evaluated how sunlight, prevailing ocean breezes, and seasonal rainfall would impact the site. More importantly, the architects spent considerable time interviewing the two friends to map out their overlapping daily routines, divergence in privacy needs, and shared aspirations for outdoor living.
Phase 2: Spatial Partitioning and Zoning
Instead of treating the plot as a standard subdivided urban lot, the design team viewed the property as a unified ecological and social landscape. The footprint was meticulously mapped to ensure that both houses received optimal natural lighting and cross-ventilation. Public-facing areas were designed to blend seamlessly into the surrounding neighborhood context, while private living quarters and interior courtyards were carefully shielded to create intimate sanctuaries.
Phase 3: Construction and Material Selection
True to Terra e Tuma’s signature architectural ethos—recognized globally for its mastery of raw concrete, structural clarity, and economy of means—the Campeche Houses rely heavily on expressive, unadorned materials. Exposed concrete, durable masonry, and large expanses of glass form the primary vocabulary. This palette was chosen not only for its aesthetic timelessness but also for its resilience against the salty, humid sea air of southern Brazil.
Phase 4: Finalization and Documentation
Following the completion of construction, architectural photographer Débora Jank documented the project. Her images highlight the interplay of heavy concrete structural elements with soft, tropical vegetation and shifting patterns of natural sunlight. The project was officially released to the public on October 7, 2026, instantly drawing widespread acclaim across international architectural platforms like ArchDaily.

Materiality and Climate Response
The choice of exposed concrete is a defining characteristic of Terra e Tuma’s portfolio, and it serves a dual purpose in the Campeche Houses. Structurally, it provides the immense rigidity required to withstand coastal weather patterns. Environmentally, the thermal mass of the concrete absorbs heat during peak tropical afternoons and releases it slowly as temperatures drop at night, contributing to a more stable indoor climate.
Furthermore, the integration of courtyards acts as an environmental lung for the architecture. These open-air voids draw cool ocean breezes deep into the floor plans, minimizing the reliance on mechanical air conditioning and aligning the project with contemporary sustainable design principles.
Official Insights and Architectural Philosophy
According to the design statement provided by Terra e Tuma Arquitetos Associados, the core philosophy of the project centers on the negotiation of boundaries. In traditional real estate developments, property lines are rigid legal constructs that isolate neighbors from one another. In contrast, the Campeche Houses treat the boundary as an active, negotiable space.
"Two friends and a shared plan: to build their homes in Florianópolis. Choosing a shared plot of land in Praia do Campeche was not only pragmatic but also symbolic. Thus arose the challenge of designing two independent residences on a single lot, keeping in mind the autonomy of each—as well as the potential for closer, almost communal, interaction."
— Terra e Tuma Arquitetos Associados
This official stance underscores a growing cultural shift in contemporary architecture. As land costs rise and urban environments become increasingly fragmented, architects are being asked to rethink how people can live together without sacrificing personal sanctuary. By prioritizing shared spatial experiences—such as communal gardens, shared entry sequences, and interstitial outdoor rooms—the architects have proven that modern density does not have to come at the expense of human connection.
Implications for Modern Coastal and Urban Housing
The completion and critical reception of the Campeche Houses carry significant implications for the future of residential design, particularly in high-demand coastal regions like Florianópolis.
1. Reimagining Co-Housing and Shared Land Models
As coastal property values skyrocket across the globe, traditional single-family homeownership is becoming increasingly out of reach for many middle-class and professional buyers. The model demonstrated by Terra e Tuma offers a viable alternative: cooperative land acquisition combined with bespoke, architect-designed density. By pooling resources, friends or extended family members can secure prime locations without falling victim to speculative real estate developers who mass-produce generic, alienating housing blocks.
2. Tropical Modernism and Climate Resilience
The project also reinforces the enduring relevance of Brazilian tropical modernism. By utilizing durable, low-maintenance materials like exposed concrete and designing specifically for passive cooling and natural ventilation, the Campeche Houses offer a sustainable blueprint for coastal development. In an era marked by climate change and rising energy costs, architectural solutions that work with the local environment rather than fighting against it are more critical than ever.
3. The Balance of Autonomy and Community
Perhaps the most profound takeaway from the Campeche Houses is their psychological success. Urban sociologists frequently warn against the psychological toll of isolation in modern cities, yet people simultaneously guard their privacy fiercely. Terra e Tuma has demonstrated that architecture can successfully bridge this divide. By carefully calibrating sightlines, private entries, and shared courtyards, the design allows the two friends to share a property line while maintaining the absolute peace of mind that comes with a private home.
Conclusion
The Campeche Houses by Terra e Tuma Arquitetos Associados are far more than just two buildings on a single plot of sand in Florianópolis. They represent a thoughtful, beautifully executed meditation on friendship, shared resources, and modern coastal living. Through masterful handling of concrete, light, and space, the architects have crafted a timeless retreat that honors both individual autonomy and collective harmony—securing its place as one of the most compelling residential projects of the decade.
