La matriz de opciones — the matrix of options — is the tool we use to make design decisions transparent. The principle is simple: present two or more alternatives against the same criteria, derived from the project brief, so the client decides by comparing, not by guessing. The process before the style.
Why Comparison Is the Honest Design Method
Most architectural presentations show one scheme. The architect selects what they consider the best option and presents it with conviction. The client either accepts it or asks for changes.
This model puts the client in a passive position. They cannot evaluate the recommendation against alternatives because no alternatives are shown. They must trust that the architect's judgment aligns with their priorities.
The matrix of options inverts this. It assumes that two or three intelligent responses to the same brief are possible, each with a different set of tradeoffs. The client's role is to choose which tradeoff set fits their priorities — not to ratify the architect's preference.
This is not relativism. The architect still has a position. The matrix includes the architect's recommendation, and the criteria are structured to make that recommendation legible. But the client sees why.
How to Build a Design Matrix
The matrix has two axes: options and criteria.
Options (columns) are two to four distinct design schemes. In a residential project, these might be: a linear scheme organized along a single circulation spine; a courtyard scheme where the patio is the organizer; a stacked scheme where public and private programs are vertically separated.
Criteria (rows) are drawn directly from the program brief. Typical residential criteria:
- Fit to program: does the scheme accommodate all the required spaces?
- Climate response: how well does the orientation and section manage solar gain and natural ventilation?
- Construction cost: rough order of magnitude, not a bid
- Material compatibility: does the structural system allow the specified materials?
- Circulation logic: how many steps from entry to any room?
- Privacy gradients: are the private spaces adequately separated from the social spaces?
- Extendibility: can the building be modified or expanded in the future?
Each cell gets a rating — not a number, but a judgment: optimal, acceptable, constrained. The cells where options diverge are where the client makes the decision.
What the Matrix Reveals That a Single Presentation Does Not
When a client sees two options side by side, patterns emerge that are invisible in a single-option presentation:
- Option A has a better climate response but a less efficient circulation path. That tradeoff is real. The client can decide whether climate performance or circulation efficiency matters more in their daily life.
- Option B costs less to build but requires a structural system that limits future modifications. If the client plans to expand in 10 years, Option B's cost advantage disappears over time.
- Option C addresses the view but sacrifices the garden connection. For a client who gardens, that is disqualifying. For a client who does not, it is not.
None of these judgments can be made without comparison. The matrix makes comparison possible.
When the Matrix Is Used Beyond Schematic Design
The matrix logic applies beyond design options. In MÉTODO, we use comparison structures for:
- Material selection: three stone options, three finish options, scored against cost, maintenance, and light behavior
- Contractor bidding: bids compared not only on price but on proposed schedule, exclusions, and references
- Window type selection: options compared on thermal performance, cost, lead time, and operability
- Landscape strategy: planting approaches compared on water use, maintenance frequency, and seasonal behavior
The underlying principle is the same: decide by comparing, not by default.

If you have worked with architects before and felt uncertain about why a particular design was recommended, it is worth asking for a comparison in your next project. A matrix presentation takes the architect more time to prepare — and it should. That preparation is part of the service.
