Core House / AGA estudio is a 2016 social-housing project that treats a family home as both domestic space and a productive neighborhood hub. Developed for the Marchán family, the design brings cooking, cultivation, exchange and cooperation into the house instead of separating them from everyday living. AGA estudio also describes the building as a collaborative self-build, made with fourteen neighbors and three visitors working as a temporary cooperative. Its vertical, terrace-like layout creates usable ground in a constrained footprint and leaves room for future adaptation.
What Core House is
ArchDaily lists Core House / AGA estudio as a 2016 social-housing project by AGA estudio. The architects developed it for Aura, Wilder, Moisés and Ángela of the Marchán family. Their account frames the house as a response to two conditions that are often treated separately: the needs of domestic life and the productive activity that supports a household and its neighborhood.

The architects identify food, knowledge, manufacturing and social goods as examples of activity that can sustain community life. The house is therefore planned as more than a collection of bedrooms and service rooms. It is a place where family routines, shared meals, cultivation and exchanges with neighbors can overlap.
That interpretation belongs to this family and the community described by the architects. It should not be read as a claim that every informal settlement, peripheral neighborhood or household operates in the same way. Core House is a specific architectural response to the Marchán family’s circumstances and aspirations.

Why the house is organized around productive life
The kitchen as a social and economic center
The family kitchen is the clearest expression of the project’s idea. The architects describe it as a focal point for cooperation with neighbors. People shared meals there and exchanged goods that had been grown or acquired, creating a small neighborhood economy embedded in ordinary domestic routines.
This arrangement changes the role of the kitchen. It is not simply a back-of-house room reached after passing through the “important” spaces. Cooking becomes a way to host, trade, teach and coordinate. A meal can be both family time and a social resource; ingredients can move between household gardens and neighboring homes; knowledge can circulate while work is being done. The plan gives these activities a central place rather than treating them as incidental uses.

Domestic and productive uses are deliberately interwoven
Core House does not propose a separate building for every activity. Instead, it allows the same home to support resting, eating, cultivation, exchange and making. That overlap is especially important where a household’s resources, work and social relationships are closely tied to its dwelling.
The productive-center idea also explains why the architects discuss social goods alongside food and manufacturing. Production here includes forms of mutual support: preparing something for others, sharing what has been grown, passing on practical knowledge or creating a setting where neighbors can cooperate. These are architectural concerns because they affect where people gather, how materials move and which rooms remain accessible during the day.
A project-specific reading, not a universal model
The description does not provide a survey of other households or evidence that the same arrangement produces identical outcomes elsewhere. Core House should therefore be understood as a carefully situated case study. Its value lies in showing how a design team can translate a family’s existing social and productive patterns into space, not in offering a one-size-fits-all formula for informal housing.

How community participation shaped construction
A temporary work cooperative
AGA estudio says the house was collaboratively self-built by fourteen neighbors and three visitors. The group was organized as a temporary work cooperative rather than as an anonymous labor force. That distinction matters: the people who helped construct the building were connected to the household and its neighborhood, and their participation formed part of the project’s social structure.
Recommended Free Tools
The architects describe the process as an ongoing adjustment to several practical realities: construction and administrative conditions, available materials and finances, operational constraints, and the community’s needs and aspirations. In other words, the design was not treated as a fixed drawing that simply had to be executed. Decisions had to remain responsive to what could be obtained, afforded, approved and built by the participating group.
What the participation claim does—and does not—tell us
- The documented count is fourteen neighbors plus three visitors.
- The architects characterize the work as collaborative self-building within a temporary cooperative.
- The account indicates adaptation to material, financial, administrative and operational conditions.
- The description does not provide a construction schedule, labor-hour total, detailed cost breakdown or technical specification for the building system.
Participation should not be confused with a promise that every future resident can build in the same way. The project demonstrates one method of organizing labor and decision-making for this house; it does not establish a universal construction standard or a guaranteed reduction in cost.
Spatial strategies: making usable ground by building upward
Terrace logic across multiple levels
The project replaces a previous structure and reinterprets terrace logic across several levels. Rather than spreading every function across a single floor, the design develops vertically. This move creates usable “ground” within the available footprint: different levels can support planting, circulation, gathering and private rooms while remaining part of one compact home.
Vertical development is not presented as a stylistic gesture. It is a response to limited space and to the desire to bring outdoor and productive conditions into the dwelling. The terraces allow the house to contain more than one kind of ground without requiring a larger site.

Cultivable ground and an internal courtyard
AGA estudio’s description says the proposal brings cultivable ground and a courtyard into the home. These elements give the family places for growing and for being outdoors while remaining within the building’s spatial system. A courtyard can also provide orientation, daylight and a shared point between levels, although the source does not publish measured environmental performance or technical drawings that would quantify those effects.
The important point is organizational: planting and open space are not left outside the architectural brief. They are treated as parts of domestic infrastructure, alongside the kitchen and sleeping areas.
Sleeping and resting above the kitchen-dining area
Sleeping and resting spaces are located above the kitchen-dining area. This vertical arrangement places the most socially active part of the house below the quieter rooms. During the day, the lower level can support cooking, eating and exchange; above it, the family has areas for retreat and rest.
The arrangement also makes the house legible as a sequence of degrees of privacy. The kitchen-dining level can connect to neighbors and shared activity, while the upper rooms provide separation without requiring a completely separate building wing.
Modules intended for progressive expansion
The design uses modules intended to allow progressive future expansion. The architects describe the proposal as open-ended and say it can generate more than ten variations. That figure refers to the range of configurations the modular system is capable of producing; it is not evidence that more than ten additions have actually been built.
Rank #4
A progressive model can be useful when a family’s resources, household size or working practices change over time. Initial construction can establish a functioning home, while later work may add or rearrange spaces as needs develop. The source does not specify the module dimensions, structural limits, approval process or sequence for adding each variation, so those decisions would require project-specific engineering and local permitting.
How the main ideas work together
From kitchen to courtyard
The kitchen-dining area, courtyard and cultivable ground form a connected social and productive core. Food can be prepared where people gather, cultivation can remain visible and accessible, and the courtyard can help connect activities on different levels. This is a spatial interpretation of the neighborhood relationships the architects describe, not an assertion that every activity occurs simultaneously.
From cooperative building to adaptable form
The participatory construction process and the modular plan address different phases of the house’s life. Cooperative self-building responds to how the initial structure can be made under real constraints. Modular expansion responds to what may happen after occupation. Together they suggest a house that is expected to change, rather than a finished object whose form and use are permanently fixed on the day construction ends.
From peripheral conditions to a positive spatial strategy
The architects associate the project with conditions of informal peripheral development. Core House does not simply reproduce those constraints; it turns them into design questions. Limited ground becomes a reason to build vertically. The need for productive activity becomes a reason to centralize the kitchen and include cultivation. Changing resources become a reason to plan for progressive growth. The result is a strategy for working with constraints while preserving opportunities for collective life.

A careful reading of the project page keeps the known facts separate from details that are not supplied. The following points are not established in the available account:
Best Value
- The exact geographic location of the house.
- Site area, floor area, room dimensions or total height.
- Structural system, construction layers, insulation values or building-services specifications.
- Budget, financing terms, construction duration or labor-hour totals.
- Current occupancy, present condition or the number of expansions completed since the original project.
- A measured evaluation of energy use, water management, crop yield or economic impact.
Those omissions do not weaken the architectural concept; they define what can responsibly be said about it. Core House can be discussed as a documented design and construction approach, but not as a verified performance study or a complete technical specification.
How to understand the project as a housing precedent
For architects and students
The project offers a useful set of questions for housing design: What household activities are actually productive? Which room should anchor cooperation? How can a compact footprint provide outdoor or cultivable ground? Where should private rooms sit in relation to a socially active core? What parts of the plan can remain open to future change?

Its modular strategy is particularly instructive because it links flexibility to a real household rather than presenting flexibility as an abstract diagram. The stated capacity for more than ten variations shows an intention to accommodate change, while the absence of documented built variations is a reminder to distinguish design potential from post-occupancy evidence.
For community-led housing groups
The described cooperative process highlights preparation as much as construction. A group considering a similar approach would need to define responsibilities, access to tools and materials, safety procedures, decision-making authority and how administrative requirements will be handled. The architects’ account confirms that these conditions influenced the project, but it does not provide a transferable rulebook.
For readers interested in social housing
Core House broadens the definition of housing quality. Adequate shelter remains essential, but the project also asks whether a home can support food production, knowledge exchange, mutual aid and small-scale making. Its answer is spatial: place the kitchen and shared life at the center, bring cultivation into the plan, and allow the building to evolve as the family evolves.
Why Core House matters
Core House matters because it connects three decisions that are often separated in housing discussions. First, it recognizes the home as part of a neighborhood economy rather than an isolated private container. Second, it treats construction as a collective process shaped by available resources and local relationships. Third, it gives physical form to future change through vertical terraces, a courtyard, cultivable ground and modular expansion.
The project’s strongest lesson is not a particular material or a purchasable building component. It is the idea that social, productive and domestic life can be planned together. In the Marchán family’s case, that meant a kitchen-dining center linked to cooperation, upper-level resting spaces, and a compact but expandable arrangement of terraces and courtyards. The architects present those moves as a response to one family and its community; their significance comes from how clearly the design makes that relationship visible.
