An open concept kitchen in a Mexico City residence creates one of the most complex spatial design problems in residential architecture: how to connect the kitchen to living and dining areas without the walls that contain cooking smells, manage noise, and create the visual separation that makes a kitchen functional as a workspace. At MÉTODO, open plan kitchens in CDMX are resolved in section and plan simultaneously — because the spatial quality depends on decisions in both dimensions at once.
The Seismic Constraint in CDMX Open Plans
Before any open concept kitchen design begins in Mexico City, the structural reality must be documented. Mexico City sits in one of the world's most seismically active zones, and the lacustrine zone — the former lakebed that underlies much of the central districts — amplifies seismic motion significantly. Masonry structural walls in CDMX apartments and houses carry loads that are also lateral bracing elements against seismic forces.
An open plan kitchen that requires removing a wall must begin with an existing conditions survey that identifies every wall's structural role. In MÉTODO, this survey includes a structural engineer review before any schematic design that involves wall removal. An infill masonry partition can typically be removed with minimal structural intervention. A structural wall removal requires a new lateral resisting element — a beam, a column, a moment frame — that becomes part of the design rather than a problem to be solved by the contractor.
This is not a risk management step — it is a design step. The structure that replaces a removed wall is a compositional element.
Spatial Definition Without Walls
An open concept kitchen that reads only as a large undifferentiated room is not a well-designed open plan — it is an undifferentiated room. At MÉTODO, open kitchen design uses four tools to define kitchen territory without physical separation:
Floor material change. A stone or concrete floor in the kitchen continuing as wood or a different stone in the living area defines the zone boundary at the ground plane. This works when the floor plane is the primary spatial datum — ground-level reading, not ceiling level.
Ceiling height variation. A dropped ceiling over the kitchen work zone — 20 to 30 cm lower than the main living ceiling — creates a spatial enclosure without walls. This also improves kitchen acoustics by reducing the volume of kitchen air that connects directly to the living space.
Island as boundary. The kitchen island, positioned perpendicular to the kitchen-living connection, creates a physical and visual threshold. Standing at the island, you are in the kitchen; sitting at the island's bar counter, you are in the dining-kitchen transition zone. The island's material — concrete, stone countertop, wood base — makes it read as a kitchen element rather than living room furniture.
Lighting zones. Task lighting over the kitchen work plane (pendants, under-cabinet linear LEDs) creates a distinct light zone that separates from the ambient lighting of the living area. In an open plan, lighting design is a spatial zoning tool.
Ventilation in Open Plan Kitchens
The single greatest technical challenge of open concept kitchen design is ventilation. An open kitchen connects its cooking zone to a much larger air volume — the living and dining areas — which means cooking odors and steam disperse into that volume rather than being contained in a kitchen box that can be ventilated directly.
The response is a high-capture-efficiency hood sized for the enlarged connected volume, not only the kitchen footprint. In a CDMX open plan kitchen with a combined kitchen-living-dining area of 80 square meters, the effective volume the hood must clear is far larger than in an equivalent closed kitchen. Hood CFM requirements scale with the connected volume.
In MÉTODO open kitchen projects, the mechanical engineer specifies the hood for the combined volume and designs the makeup air strategy for the open plan. A hood that creates negative pressure in a sealed closed kitchen can create noticeable pressure differentials in an open plan, affecting how doors close and how the building envelope performs. This is a mechanical coordination problem that must be solved in design, not in construction.
Acoustic Management in Open Plans
Cooking is not quiet — range ventilation, food preparation, appliances, and conversation at the kitchen island all contribute to a noise environment that in a closed kitchen stays in the kitchen. In an open plan, this noise enters the living and dining areas directly.
Acoustic management strategies in MÉTODO open plan kitchens:
- Mass concrete island: Dense materials absorb and attenuate sound better than light ones. A concrete island at the boundary between kitchen and living acts as a partial acoustic barrier.
- Ceiling treatment over kitchen: Acoustic panels or sound-absorbing material at the kitchen ceiling plane reduces reverberation within the kitchen zone and the volume of sound that transmits to the living area.
- Appliance selection: Dishwashers, refrigerators, and range hoods all have published noise levels. For an open plan kitchen, selecting lower-decibel appliances is a practical decision, not a luxury.
- Hood placement: A ceiling-integrated concealed hood is quieter than a surface-mounted chimney hood at equivalent CFM. In an open plan where the hood noise travels freely, this difference is audible.
Material Continuity and Contrast Across the Open Plan
In an open concept kitchen in Mexico City, the material palette must work across the combined kitchen-living-dining zone, not only within the kitchen. At MÉTODO, open plan material strategies take one of two positions:
Continuity: The same stone floor, the same plaster wall finish, and the same ceiling plane run from kitchen to living without interruption. The kitchen is defined by its furniture (island, appliances) and lighting zones, not by material change. This produces a spatially generous result but requires careful kitchen furniture design to read as a kitchen and not as living room.
Contrast: The kitchen has a distinct material — stone floor where the living area has wood, or a concrete ceiling over the kitchen where the living ceiling is plaster — that marks the zone boundary. This is more spatially complex but clearer in its organization.
The choice between continuity and contrast is made in response to the plan's proportions and the client's way of living. A client who entertains and cooks simultaneously benefits from material continuity that reads as one space. A client who wants the kitchen as a dedicated workspace benefits from material contrast that defines the zone.

Open concept kitchen design in Mexico City is not simply about removing a wall — it is a structural, acoustic, mechanical, and spatial design problem that requires complete resolution before demolition begins. The quality of the result lives in the decisions made before construction starts.
