Enekén Studio Wraps an Ancient Stone Ruin in Pink Walls and Poolwater in Mérida

Some projects restore old buildings. Others build new ones that look old. Enekén Studio, led by architect Miguel Tapia, did something more interesting in Mérida: they found a decaying structure with a stone ruin of unknown age at its center, and rather than clearing the site, they built the entire house around it. The ruin now sits in a shallow reflecting pool, framed by pink stucco walls and arched timber doors, functioning as the emotional anchor of a 315-square-meter family residence called La Casa Rosa. The name is not metaphorical. The owners' daughters wanted to live in a pink house, and the original facade was already that color. Tapia kept it.

What makes La Casa Rosa worth studying is not the color or the sentimentality. It is the way the project uses traditional Yucatán construction materials and passive climate strategies without turning them into a museum exhibit. Chukum resin waterproofing, locally sourced hardwoods like tzalam and ciricote, elliptical arches that block direct sun, ventilation chimneys that pull hot air upward: these are not decorative gestures. They are the building. Every detail serves the tropical climate while maintaining visual cohesion with the surrounding neighborhood, where the pink facade reads as one more old house on the street, not a renovation announcement.

A Facade That Refuses to Announce Itself

From the street, La Casa Rosa is almost invisible as a design project. The pink stucco facade with its pair of timber louvered doors sits beneath overhead power lines like every other house on the block. This is deliberate. Enekén Studio retained the original facade language, preserving not just the color but the scale and rhythm of the street wall. The elevation drawing confirms the symmetry: two arched doorways, nothing more. In a city where new construction often disrupts the visual grain of colonial neighborhoods, this restraint is the project's first and most important move.

The Ruin as Centerpiece

The ancient stone masonry fragment at the heart of the property is the most striking element of the design. Its arched openings, weathered surfaces, and rough-cut limestone stand in direct contrast to the smooth pink plaster that surrounds it. Rather than compete with this texture, the architects let the ruin breathe by placing it beside a reflecting pool that doubles its visual presence. Looking through the ruined archway toward the interior courtyard, you see palms, arched timber windows, and layers of depth that make the house feel much larger than its footprint.

The decision to preserve rather than demolish required the entire floor plan to organize itself around an irregular historical artifact. That constraint produced the labyrinthine quality of the house, where rooms connect through varying ceiling heights and elliptical arches rather than straight corridors.

The Courtyard as Climate Machine

Mérida is hot. The courtyard pool is not a luxury amenity; it is a cooling device. Water absorbs heat during the day and radiates coolness at night, and the narrow proportions of the courtyard channel breezes between the pink walls. Dappled palm shadows fall across the surfaces, reducing solar gain on the stucco. At twilight, the narrow passage between plastered walls and the preserved stone archway becomes a thermal chimney, drawing warm air upward and pulling cooler air in at ground level.

The arched timber doors along the pool edge can be opened fully, collapsing the boundary between interior and exterior. This is bioclimatic design at its most practical: no mechanical systems, just geometry, water, and vegetation working together.

Passages and Vertical Moments

The circulation through La Casa Rosa is deliberately indirect. Preserved stone ruins, rendered walls, and arched openings create a sequence of courtyard passages that reveal the house gradually. You never see the whole property at once. This compression and release, tight passage followed by open courtyard, is a spatial strategy borrowed from traditional Yucatán haciendas, where thick limestone walls defined a series of outdoor rooms rather than a single open plan.

The staircase with its circular wall openings and mature tree overhead is one of the house's most compelling moments. The tree was not planted; it was preserved, and the facade was cut to accommodate it. A stacked timber sculpture by Tapia, created under his MATA brand, sits beside potted plants on the exterior stair, blurring the line between architecture and craft.

Interiors Built from Yucatán

The dining room captures the project's material logic in a single frame. Terracotta tile floors, a pink vaulted ceiling, and clerestory lighting that washes the walls without introducing direct glare. There is no imported marble, no polished concrete. Every surface is local: chukum resin plaster, which provides a smooth, moisture-resistant finish derived from the resin of the chukum tree mixed with lime and water; pasta tiles in the traditional Yucatán pattern; and locally sourced hardwoods shaped by regional artisans.

The bedroom continues this approach with earthen plaster walls, a timber-framed bed, and warm afternoon light filtered through deep-set openings. An arched niche with gridded timber shelving, set into a pink plastered wall, functions as both storage and display. The wabi-sabi aesthetic that Enekén Studio references in its design philosophy is visible here: surfaces that will age, darken, and patina over time rather than deteriorate.

Water, Stone, and the Private Rooms

The three bedrooms are located at the back of the house, each with private terraces and outdoor bathtubs. The bathroom interior, with its glazed shower door and terracotta vessel sink, reflects the same restraint found throughout the project. Natural light enters from above, illuminating the chukum-finished walls without the need for artificial lighting during the day. These private spaces are tucked behind the labyrinthine sequence of courtyards and passages, offering genuine separation from the social zones at the front of the house.

Plans and Drawings

The ground and upper level floor plans reveal the organizational logic: all living spaces, kitchen, dining, and living room, are arranged along the courtyard with pool at the front of the house, while bedrooms occupy the rear. The central courtyard is not centered; it is offset, following the footprint of the existing ruin and the mature trees that were preserved on site. The transverse and longitudinal sections show how the two-level structure steps down toward the courtyard, creating double-height volumes at the staircase and lower ceilings in the sleeping areas. The tree at the center of the section drawing is not ornamental; it is structural to the design concept, holding the entire composition together.

Why This Project Matters

La Casa Rosa matters because it demonstrates that sustainability in architecture does not require technological novelty. Chukum waterproofing, ventilation chimneys, deep-set openings, courtyard cooling, and locally sourced hardwoods are all pre-industrial techniques. Enekén Studio did not rediscover them; they simply refused to abandon them. In a region where new construction increasingly defaults to reinforced concrete and mechanical air conditioning, this house is a counter-argument made in limestone, resin, and pink plaster.

It also matters as a model for working with existing structures. The stone ruin at the center of the property could have been demolished in an afternoon. Instead, it became the organizing principle of the entire plan, the reason the circulation is labyrinthine, the reason the pool exists, the reason the house feels like it has been there for centuries even though much of it is new. That decision, to let an old broken thing define the shape of a new whole thing, is the kind of architectural thinking that produces buildings worth visiting decades from now.
