The blocks for the top floor, bearing less load, are made of 100% lime concrete, while the rest of the floors combine lime with cement. These blocks, approximately 135 cm long, 42 cm high, and with variable widths for each floor (64, 54, 44, and 34 cm), were prefabricated once the demolition was completed, before commencing the construction of the new building. This approach significantly reduced the construction duration. The blocks were stacked to build load-bearing walls perpendicular to the street, supporting cross-laminated timber ceilings. On each floor, the walls reduce in thickness by 10 cm, allowing direct support of the timber panels, facilitating the speed of execution of the entire structure.

Perpendicular to the main walls, 13 cm thick partition walls, constructed with the same cyclopean concrete and resulting from cutting a 60 cm wide block into four 13 cm sections, tie the structure of the entire building, together with the stair and elevator core.

The entire spatial and programmatic organization of the building responds to the described structural system; the floor plan is organized with a stair core in the corner, providing access to a walkway in the interior garden, from where each apartment is accessed—all are through apartments except those on the semi-basement floor, which, like those on the attic floor, have half the depth of the typical floors and utilize two structural spans for each apartment. The top-floor apartments have large terraces. Each floor also has a communal area (laundry room, lounges, etc.). The façade starkly displays the structural system: the end walls (vertical) of the prefabricated block walls, which decrease in height on each floor and support the timber (horizontal) ceilings, and, as the façade of each apartment, floor-to-ceiling wooden balconies with a lateral opaque strip and Venetian blinds to protect from the eastern and western sun.

A politically committed and militant project!

The nucleus is resolved by using a wall of compacted earth blocks (CEB). The block is distributed through 3 large units adapted to the program; it generates open spaces for storage or facilities, enclosed spaces with their own program, and passage spaces that interconnect or separate areas. At the same time, in order not to alter the original stone walls, the block concentrates all the installations of the cohousing.

In terms of comfort, this large earth block provides a high hygroscopic property, which compensates the low capacity of existing stone walls to humidity regulation. In addition, it compensates part of the thermal inertia that is lost through the thermal insulation of the existing façades on its interior side.

The compact volume, conceived through a passive design strategy to reduce the building’s energy demand, organizes the overall layout. On the access side, it defines a public square; on the other sides, it encloses the more private areas that make up the nursery school spaces: the south-facing classroom patios, the shared patio to the east, and the service strip located on the northern side.
A central courtyard promotes cross ventilation and the entry of natural light. This void creates a new educational space that, while outdoors, is protected from the wind. Its visibility from all interior spaces facilitates supervision and control of the children.
Solar control is optimized through the classroom porch and the incorporation of vegetation within the courtyard. Cross ventilation is planned both in plan and section, enhanced by large openings on the south-facing façades and smaller, higher openings on the northern façade.
The construction adopts a sequence of vaults that evoke the primal sense of shelter through their concave form. The structural system is organized through the repetition, in each bay, of a curved profile made of laminated timber beams. The building is modulated into six bays, each seven meters wide. These beams naturally resolve the slope of the roof. The ceramic roof highlights the path of rainwater. Just as the façade guides the entry of light, the roof shapes the itinerary of water, so that rain ceases to be a mere residue.
This spatial configuration gives rise to a warm and sheltered interior, generating a welcoming atmosphere for early childhood—a place that embraces, protects, and conveys calm.
The building is organized into three longitudinal strips. A central courtyard acts as the heart of the building, arranging the rooms around a continuous circulation. This space not only hosts children but also educates them. Constructive honesty, based on exposing structures, textures, and natural materials—without superfluous finishes or additive layers—turns the space into a didactic support. Matter becomes legible and tangible: what children see and touch explains how the building is constructed.
The impact on natural resources is reduced through the use of materials with a low environmental footprint, both during construction and throughout the building’s life cycle, prioritizing efficient construction systems, materials with controlled life cycles, and passive strategies.
Thermal mass is concentrated in elements in contact with the ground, such as concrete slabs, stone walls, and brick masonry. The roof, more exposed to solar radiation, is resolved as a lightweight, ventilated system with low thermal inertia, whose light-coloured ceramic tiles reduces solar absorption in summer.
The building is supported by a set of active systems that enhance its efficient performance and reduce its environmental impact.
The architecture is based on four principles: a climatic response tailored to the context, high energy efficiency through passive strategies, the use of natural, local, low-impact materials, and efficient technology that supports the building without imposing itself.
The result is a kind and welcoming building, where form, construction, and use combine naturally, giving rise to a comprehensible and habitable space that seeks to integrate respectfully into the landscape.

Most of these industrial spaces are located on the ground floors of residential buildings, extending beyond the building’s footprint into interior courtyards. In a cityscape now dominated by residential and commercial uses, these large-volume spaces are no longer needed. Urban planning policies prioritize reclaiming these courtyards, often through the demolition of industrial structures, supported by zoning changes that convert industrial properties into residential use. The most drastic transformation involves limiting the depth of new construction, making residential redevelopment of these industrial buildings unfeasible unless they are partially demolished. The financial incentive for these changes lies in the real estate market, where land values can triple or quadruple when converted into residential properties—largely driven by Madrid’s inflated rental market.

The key to preserving these spaces lies in hybrid uses. These industrial buildings cannot be understood rigidly; they require a more fluid approach to occupancy that takes advantage of their spatial qualities while balancing the costs of adaptation. Elements for Industrial Recovery explores urban and architectural tools to retain these structures in a context that otherwise incentivizes their disappearance.
CNM was originally a storage space characterized by a large, continuous pitched roof and nearly opaque lateral walls. The redesign opens this space up, reflecting the vision of its new owner—an artist whose work explores perceptual distortion through technology and digital media. Based on that, the project creates a distorted spatial experience using layered materials, shifting transparencies that transform into reflections, and interior spaces that seem to dissolve into exteriors.

The design materializes in a monumental outer wall composed of a large colonnade with a textured plaster finish. Regularly spaced openings combine fixed glass panels with overlapping sliding doors, creating a seamless interplay of transparency and reflection. The roof’s continuity is preserved as a defining element, visible from any point in the space and strategically perforated to bring natural light into key areas. The interplay between the uninterrupted roofline and the grand colonnade generates a series of overlapping spaces where interior and exterior boundaries blur, creating a dynamic depth of field.

Two distinct material volumes provide intentional contrast and serve as spatial anchors, marking the beginning and end of the journey through the space. The first is a bold yellow volume near the entrance, containing restrooms, storage, and mechanical systems. The second is a wooden structure at the far end of the building, housing additional functional elements and concluding the interior narrative.
The furnishing strategy reinforces the theme of spatial indeterminacy through a collection of movable objects. These pieces are designed to flow between zones, enabling different uses to migrate across the space. Each object is proportioned to pass through the arches, facilitating movement and interaction between areas.

By embracing flexibility, preserving architectural heritage, and integrating hybrid functions, CNM offers a forward-thinking model for the adaptive reuse of industrial spaces in a rapidly evolving urban context.

The building is strategically designed to maximise solar gain in winter and reduce cooling demand in summer, incorporating cross ventilation, solar shading, and high thermal inertia in floors and walls with humidity-regulating hygroscopy and breathability. The ‘Trombe’ type roof is a key element that captures heat in winter and is ventilated in summer, regulating the temperature and thus eliminating active systems. The private patios function as user control and filtering elements for the ventilation of the dwellings.

With near-zero energy consumption (1.7 kWh/m²-year, NZEB), the project reduces CO₂ emissions by 50%, while circularity considerations mean a waste reduction of 60%. In addition, the project has been consciously designed with building systems where materials can be separated for reuse in the event of demolition. The Life Cycle Analysis demonstrates a low CO2 cost in construction (230 Kg Co2/m2), a 50% reduction compared to conventional constructions.

The result is a housing complex that reduces its environmental impact while strengthening the local economy and promoting territorial regeneration. By incorporating vernacular materials and techniques, Ses Veles Puigpunyent proposes an architecture in dialogue with the island’s culture, combining technical innovation and environmental responsibility.

The modules’ flexibility and multiple connections enable the house to function as a single open space or separate areas. The staggered layout enhances visual relationships in all directions, creating a sense of spaciousness and a strong connection to the garden. At the heart of the house, the central module rises above the rest to increase solar gain in winter and improve cross-ventilation in summer.

The construction is simple, with load-bearing brick walls, concrete flooring, and vaulted ceilings. Our goal was to create a building with high thermal mass, which, combined with ample solar gain in winter and effective ventilation in summer, ensures optimal thermal comfort throughout the year.

The house is connected to the garden through planted pergolas that mirror the structural grid, forming outdoor spaces that act as climatic shelters and encourage interaction with the surrounding natural environment.

The plot, located in a suburban neighborhood, has a rectangular area of 923.34 m2 bordered on the north-east by industrial buildings, on the northwest by Anselm Clavé street and on the south-east and south-west by green spaces and communal areas of a neighboring apartment building. The ground floor defines an interior passage that communicates the street and the park providing connectivity and integration between the two urban areas all the while dividing the space into two enclosed spaces for commercial and public use. Its shape follows the nature of its surroundings for better integration and its hard-based finishes facilitate accessibility and maintenance. In turn, the façades are defined by balconies that occupy the maximum surface allowed by local regulations, which limit their presence to the 50% of the façade.

By strictly following a fan-like shape, the project extends the exterior surface of the apartments to the maximum allowed, defining large outdoor spaces.
