Retail Co-location Methodology
Retail development capital is usually committed on comparables and analyst sentiment. Whether independent demand actually converges at a site — the reason it should succeed — is assumed rather than measured.
The Woodfine co-location methodology measures it. It ranks development sites by the objective convergence of independent, capital-intensive retail operators, not by market sentiment or analyst forecasts. The framework is operationalised by the deterministic ranking system and exposed to platform users via the co-location intelligence overview.
A node qualifies when a hypermarket, a warehouse club, and a home-improvement superstore have each independently committed capital within 1.0 to 3.0 km of one another. Each operator runs its own site-selection process; convergence is independent corroboration, not a single forecast. The qualification logic, cluster formation, and the anchor adjacency requirement are the three structural inputs to the index.
For a capital allocator the index is a defensive filter: it prioritises the sites where several parties have independently validated the trade area. This article covers the Named-Anchor Model, the three operator tiers, and the five quality tiers; sibling articles describe the O-D catchment methodology, the trade-area data sources, and the catchment ranking methodology.
The Named-Anchor Model
Large-format retailers apply rigorous, data-driven site-selection criteria before committing capital to a market. When several independent operators converge on the same geographic node, that convergence signals a validated commercial corridor — a location where multiple parties have independently confirmed the trade area's strength.
The methodology sorts these operators into three tiers, by commercial function and foot-traffic contribution.
Primary Targets — the anchor
The foundational requirement for any evaluated node; the core traffic driver.
- North America: Walmart Supercentre.
- Europe: IKEA, as the operational baseline.
Secondary Targets — commercial support
Complementary large-format operators that validate the trade area's commercial depth. They are evaluated within a strict 1.0 km to 3.0 km catchment radius of the Primary Target.
- Secondary-1 (hardware): Home Depot, Lowe's, Leroy Merlin.
- Secondary-2 (warehouse club): Costco, Sam's Club, Makro.
Tertiary Targets — institutional support
Civic and institutional infrastructure that provides a non-cyclical, stable demographic baseline. Evaluated within a 5.0 km catchment radius.
- Tertiary-A (healthcare): major hospitals and medical centres.
- Tertiary-B (higher education): universities and colleges.
Quality tiers and site validation
Sites are evaluated on a 12-rank matrix that maps to five quality tiers, separating commodity retail nodes from the rare locations where critical commercial elements converge. The map-facing labels — Regional, District, Local, Fringe — follow the ICSC retail property hierarchy described in tier nomenclature.
| Tier | Description | Commercial validation |
|---|---|---|
| ★★★★★ | Tier 5 — Full co-location | All four categories present: hardware, warehouse club, healthcare, higher education |
| ★★★★ | Tier 4 — Strong co-location | Both commercial secondaries plus one tertiary; one institutional dimension absent |
| ★★★ | Tier 3 — Partial co-location | Two categories present: a full secondary pairing, or one secondary with at least one tertiary |
| ★★ | Tier 2 — Limited co-location | One category present: hardware only, or warehouse club with a single tertiary |
| ★ | Tier 1 — Anchor only | Commercial secondaries largely absent: tertiary-only convergence, or warehouse club only |
See co-location-ranking-system for the complete 12-rank specification, the rank-to-tier mapping, and site counts by tier.
Strategy and application
The co-location index acts as a defensive filter for capital deployment. By focusing on Tier 4 and Tier 5 nodes, an investor prioritises sites with the highest level of independent capital validation and the strongest multi-format demographic anchors.
The methodology applies consistently across global markets by mapping regional operators to these canonical roles. A planned expansion integrates logistics and transport data to add a fourth dimension to the matrix; that expansion is forward-looking and framed per [ni-51-102] and [osc-sn-51-721].
