Renovating a colonial house in Mexico City means working with two timelines at once: the original construction logic of the 17th or 18th century and the present-day program the owners need. Introducing new wood into that conversation — carefully, with clear material honesty — is one of the most effective ways to make the intervention legible without erasing the original.
What Makes Colonial Houses in CDMX Different
Colonial residential construction in Mexico City relied on thick masonry walls — cantera, tezontle, adobe — and timber structural systems. The walls have thermal mass. The proportions are generous. The patios organize the program around light and air. These are not problems to solve; they are the building's logic, and any renovation that ignores them produces a house that fights its own structure.
What does need updating: mechanical systems, waterproofing, structural reinforcement in zones affected by differential settlement, and the interior finishes that have been patched and repainted over decades until the original material is buried.
Reading the Building Before Designing
The first step in any colonial house renovation at MÉTODO is a material survey. We map what is original, what is later intervention, and what is irreversible deterioration. This is not a heritage formality — it is how we decide where to spend the renovation budget.
Original stone floors that can be cleaned and relaid: we keep them. Original wood lintels that are structurally sound: we expose and treat them. Gypsum board applied over original masonry in a 1980s renovation: we remove it. The survey drives the design, not the other way around.
La sección como relato — the section drawing as the story of the building — is how we communicate these decisions to the client. A vertical cut through the house shows exactly where original fabric ends and new intervention begins.
Introducing New Wood: Principles
New wood in a colonial context has to be honest about being new. A white oak staircase in a house with a 300-year-old stone staircase landing does not pretend to be colonial — it is clearly contemporary, and the contrast is its value.
The principles we apply:
- Wood species with dimensional stability in CDMX's climate (white oak, native pine, cedar in humid zones)
- Natural oil or wax finishes that age with the wood rather than sealing it from its environment
- Joint details that are visible and resolved, not hidden behind trim
- Proportions derived from the existing column grid and room dimensions, so new millwork is in conversation with the original building module
What we avoid is the opposite tendency: staining new wood dark to match aged colonial timber. It never matches, and in 10 years the difference is more visible, not less.
The Patio as Organizer
Colonial houses in Mexico City are organized around the patio — an open-air void that provides light and ventilation to rooms on all four sides. In a renovation, the patio is the first decision: do you cover it, add a second level, or preserve it as is?
In MÉTODO we almost always vote for preserving the patio as a void. Covering it gains square meters but loses the building's climatic logic. Rooms adjacent to an open patio are cooler in the afternoon, lighter in the morning, and better ventilated year-round than rooms in a sealed envelope. This is the respuesta climática the original builders understood and encoded in the plan.
New wood elements — pergolas at the patio edge, wood screens between interior and exterior, a wood ceiling at the colonnade — can modernize the space while reinforcing the original organizational logic.
Heritage Permits and the INAH Process
Properties catalogued by INAH (Instituto Nacional de Antropología e Historia) or listed in Mexico City's heritage registry require a permit before any intervention. The permit process involves presenting design documents for review by the relevant authority, a waiting period, and sometimes revisions.
We coordinate the permit process as part of the pre-design phase. This means the client knows the regulatory constraints before design begins, not after. Permit timelines in CDMX range from three to nine months depending on the level of cataloguing and the scope of the intervention.
Not all colonial houses in CDMX are catalogued. If the property is not listed, standard urban development permits apply, which are faster. We confirm the property's status in the first meeting.
Materialidad Honesta in a Historic Context
Materialidad honesta — material honesty — means using materials in a way that reveals what they are and how they were made. In a colonial renovation, this applies to both the original fabric and the new intervention.
Exposing original cantera that was painted over. Leaving visible the joint between a new concrete slab and the original stone floor. Installing new wood with clearly modern connections that do not pretend to be hand-carved colonial joinery. These decisions produce an interior that reads as a layered history — which is what the building actually is.
Próximos pasos
A colonial house renovation in Mexico City is a long engagement — typically 18 months or more. The first conversation is about the building's current condition, the program you need, and what you want to preserve. From there we scope the project and give you a realistic picture of what a careful renovation involves.
