Building Potential Areas in Cologne for Residential Construction

A geospatial dataset identifies housing development potentials within Cologne's urban area. The data, produced by the city administration using an in-house algorithm, categorizes areas as building gaps, replenishment, and restructuring potentials. It serves as a technical initial assessment for residential construction feasibility, published under § 200 (3) of the German Building Code.

Use Cases

• Identify potential building gaps for new housing developments based on the algorithm's assessment.
• Analyze replenishment potentials for densifying existing urban areas.
• Evaluate restructuring potentials for redevelopment projects.
• Map residential construction feasibility across Cologne's inner city sub-area.

Strengths

• The dataset is derived from an algorithm developed in-house by the Cologne administration, suggesting a methodical creation process.
• It categorizes potentials into three distinct types: building gaps, replenishment, and restructuring.
• The dataset has a defined legal basis for publication under § 200 (3) of the German Building Code.

Limitations

• The description states the data is a technical initial assessment 'without legal claim to correctness or completeness'.
• Owner information is excluded for data protection reasons, limiting property-level analysis.
• As of January 2026, coverage is limited to the Inner City sub-area, with outer city areas to be added later in the year.
