Decoding Indigenous Intelligence
A|WA is an architectural research initiative investigating the construction histories, material systems, and environmental behavior of indigenous West African architecture.
Through archival research, field documentation, architectural reconstruction, material study, environmental analysis, and digital modeling, A|WA asks how historical buildings worked, how reliably their systems can be reconstructed, and what those findings might contribute to contemporary architectural research.
Research Phase 01 | 2026-2029
Nigeria serves as the initial field of investigation within a broader West African research program.
THE RESEARCH PROBLEM
THE RESEARCH PROBLEM
The Double Erasure
The Double Erasure
West African architectural knowledge is threatened by two related forms of loss.
The first is physical: buildings, materials, craft practices, and construction systems are altered, abandoned, or destroyed through urbanization, environmental change, changing economies, and the loss of skilled knowledge.
The second is intellectual: when buildings disappear, the knowledge embedded in their construction can disappear with them.
A|WA treats this second loss as a research problem.
Rather than approaching indigenous architecture only as historical form or cultural artifact, A|WA investigates it as a body of constructed knowledge—knowledge expressed through material, geometry, climate response, maintenance, labor, and spatial organization.
The objective is not to assume that historical systems were superior to contemporary ones.
The objective is to determine, through evidence, what can be documented, reconstructed, measured, modeled, and interpreted.
THE CENTRAL QUESTION
THE CENTRAL QUESTION
How can the environmental and construction knowledge embedded in historical West African architecture be reconstructed from incomplete surviving evidence?
A|WA approaches this question through four connected stages:
Evidence → Reconstruction → Analysis → Interpretation
Historical records and surviving buildings provide evidence.
Architectural reconstruction makes that evidence legible.
Environmental and material analysis tests possible performance.
Interpretation asks what the results can—and cannot—tell us.
THE FRAMEWORK
THE FRAMEWORK
From Evidence to Application
From Evidence to Application
01 — Evidence
A|WA gathers architectural, archival, material, environmental, and oral evidence from selected sites and building traditions.
02 — Reconstruction
Where buildings or systems are incomplete, A|WA distinguishes between what is documented, what is corroborated, what is inferred, and what remains unknown.
03 — Analysis
Reconstructed systems may be examined through environmental simulation, material characterization, spatial analysis, and comparative study.
04 — Interpretation
Results are evaluated against the limits of the evidence. Findings are separated from hypotheses, assumptions, and future research.
05 — Application
Where appropriate, research questions are translated into contemporary design experiments, material studies, and monitored prototypes.

Mapping Material Intelligence
Mapping Material Intelligence
A|WA uses Nigeria as an initial climatic and architectural transect within the broader West African Atlantic.
The Atlas organizes Phase 01 around three research nodes.
NODE 01 — THE NORTH
Sahel / Hot-Arid Conditions
Research Area: Zaria / Kano
Architectural Focus: Earth masonry and thermal mass
Questions:
How do wall thickness, material composition, geometry, solar exposure, and thermal properties influence the behavior of high-mass earthen construction under hot-arid conditions?
Potential Measurements:
Thermal lag, surface temperature, internal temperature, material properties, wall geometry, and structural configuration.
NODE 02 — THE SOUTHWEST
Tropical Wet-and-Dry Conditions
Research Area: Ife / Lagos / Benin
Architectural Focus: Courtyard and impluvium systems
Questions:
How did courtyard geometry, roof configuration, rainfall collection, shading, ventilation, and spatial organization interact within documented Yoruba architectural environments?
Potential Measurements:
Air movement, temperature, relative humidity, rainfall capture, solar exposure, geometry, and airflow pathways.
NODE 03 — THE SOUTHEAST
Humid / High-Rainfall Conditions
Research Area: Owerri / Nri / Enugu
Architectural Focus: Earth, timber, enclosure, and moisture management
Questions:
How did material permeability, roof geometry, spatial organization, construction detailing, and maintenance practices respond to high rainfall and humidity?
Potential Measurements:
Moisture conditions, material properties, thermal behavior, structural relationships, roof geometry, and envelope performance.
BEYOND THE PILOT
BEYOND THE PILOT
Nigeria is the entry point—not the boundary—of the research.
Future phases may trace construction traditions, material lineages, and architectural knowledge across other regions of West Africa and the wider Black Atlantic.
The purpose of that expansion is not to assume continuity.
It is to investigate how architectural knowledge changes as it moves across places, climates, political systems, material economies, and generations.

RESEARCH STATUS | A|WA distinguishes among:
RESEARCH STATUS | A|WA distinguishes among:
DOCUMENTED — supported by historical or archival evidence
OBSERVED — recorded directly in the field
MEASURED — supported by instrument-derived data
RECONSTRUCTED — developed from incomplete evidence
MODELED — produced computationally
HYPOTHESIS — proposed for testing
INTERPRETATION — analytical reading of available evidence
PROJECTED — planned future work
VALIDATED — supported through empirical or independent comparison
This distinction is central to the A|WA methodology.
