What comes first in the interior design process — materials or layout?

Layout and section first, then materials. Materials serve the spatial logic — choosing finishes before the space is resolved produces mismatches that are expensive to fix.

How does MÉTODO select stone for an interior?

We start with performance requirements — moisture exposure, traffic, light conditions — then identify regional options that meet those requirements before evaluating appearance.

What is a material schedule and why does it matter?

A material schedule is a document that lists every finish in every room with supplier, reference, application method, and maintenance instructions. It prevents field substitutions that compromise the design.

How long does the material selection phase take?

In MÉTODO, material selection runs parallel to design development — 4 to 6 weeks. Waiting until construction drawings are done delays procurement and can stall the build.

What is the biggest mistake in specifying stone and wood together?

Choosing both for appearance without establishing which is primary. Without a material hierarchy, interiors read as competing rather than composed.

Interior Design Process: Specifying Stone and Wood Materials

The interior design process for stone and wood materials follows a specific sequence — substrate audit, material logic, detailing, then selection. How MÉTODO structures it.

The interior design process for stone and wood materials is a sequence, not a shopping trip. In MÉTODO, it runs from spatial logic to substrate audit to material performance to final selection — in that order. Reversing the sequence produces interiors that look assembled rather than designed.

Phase 1: Spatial Logic Before Material Decisions

Material selection cannot begin before the space is resolved. This means:

Section height and natural light conditions are fixed
Traffic patterns and use zones are established
Wet areas, dry areas, and transition zones are identified
The structural substrate — concrete slab, wood framing, masonry wall — is confirmed

A stone floor specified before the room's light conditions are studied may be the wrong color temperature. Wood cladding specified before moisture exposure is mapped may be the wrong species. These are not style errors — they are performance errors.

The process starts with a programmatic audit of what each surface will experience: foot traffic, water proximity, UV exposure, maintenance frequency. This audit drives the material brief, which then drives selection.

Phase 2: Substrate Audit

Stone and wood are demanding of their substrates. Both will reveal a bad base over time.

For stone:

The substrate must be rigid. Flexible or deflecting structures cause stone to crack at grout lines within the first two years.
Moisture must be managed. Stone is porous and will transmit moisture from a wet slab unless isolated.
The substrate must be level within tight tolerances — typically 3mm across 3 meters for rectified stone tiles.

For wood:

The slab moisture content must be below the threshold for the specified species and adhesive system.
The substrate must be flat, not just level. Low spots collect moisture under a glued floor.
Any mechanical systems — radiant heat, for example — must be coordinated before the floor goes in, not discovered after.

In MÉTODO, a substrate report precedes the material budget. There is no point specifying a material the substrate cannot support.

Phase 3: Building the Material Logic

The process we use is the matriz de opciones — a structured comparison of material options for each surface in the project. For each zone, we document:

Two to four candidate materials that meet the performance brief
Their cost per square meter installed
Their maintenance requirements at year 1, year 5, and year 15
Their availability (lead time, supplier, minimum order)
How they relate to the other materials in the palette

The client chooses from documented options, not from an open catalog. This is a design constraint, not a limitation. It makes the decision faster and the outcome more coherent.

The palette typically has one primary material per zone: stone in the kitchen, wood in the living and bedroom zones, concrete in bathrooms and service areas. The others appear as accent or transition elements.

Phase 4: Material Schedule and Supplier Coordination

Once materials are selected, a material schedule documents every finish in the project:

Room or zone
Surface (floor, wall, ceiling)
Material name and reference
Supplier and lead time
Installation method
Finish treatment (sealed, oiled, honed, polished)
Maintenance specification

This document is not a design deliverable — it is a construction management tool. It prevents the contractor from substituting a specified stone for one that is in stock, or using the wrong sealer on a wood floor because the specified product was unavailable.

Lead time management is critical for natural materials. Quality stone is often quarried and shipped over 8 to 12 weeks. Custom wood milling takes 4 to 6 weeks. If the material schedule is not finalized before construction starts, the critical path extends.

Phase 5: Detail Drawings for Material Junctions

The junction between stone and wood — at a stair, a threshold, a kitchen island — is where the quality of an interior is visible. These transitions require drawn details, not field decisions.

In MÉTODO, every material junction is documented at 1:5 or 1:10 scale. The detail shows:

The exact dimension of the joint
Whether a transition strip is used and what its profile is
How the two materials terminate without an open gap
The substrate condition at the transition

Contractors who have these drawings build the transitions correctly. Without them, field decisions produce junctions that are too wide, uneven, or visually arbitrary.

Próximos Pasos

If you are planning an interior project with stone and wood, the most valuable thing you can do before meeting an architect is document what your substrate is made of and whether any moisture issues exist. That information determines what is possible before aesthetics are discussed.

In MÉTODO, the material process is structured and documented at each phase. It produces interiors that read as designed rather than assembled. Conoce el método de MÉTODO to see how we work from brief to built.
