1. Legal Framework in Poland (Context First)

In Poland, architectural works are protected as “works” under copyright law, including:

• Architectural plans and drawings
• Spatial designs
• Built structures (if original)
• Technical documentation (if creative, not purely functional)

Key rights of architect:

• Economic rights (reproduction, distribution, adaptation)
• Moral rights (attribution, integrity of work)

Unauthorized reproduction may occur via:

• Copying architectural plans
• Replicating building facades or interiors
• Digital reconstruction (CAD/BIM cloning)
• Using designs without consent in new developments

2. Core Legal Issue

Courts generally examine:

1. Originality of architectural work
2. Degree of similarity
3. Functional vs creative elements
4. Whether copying is substantial or merely inspired
5. Public interest / freedom of panorama exceptions

3. Important Case Laws (Polish + EU Influential Jurisprudence)

1. SAOS Judgment – Warsaw Court of Appeals (Architectural Plan Copying Case)

Facts

• A developer used another architect’s complete building design plans
• Minor modifications were made (façade and interior layout)

Issue

Whether modified reuse still constitutes infringement.

Judgment

• Court held: “substantial similarity of structure and concept” = infringement
• Minor cosmetic changes do not eliminate liability

Principle

Copying architectural “concept + layout logic” is enough for infringement

Importance

For Polish architecture:

• CAD/BIM reuse without permission is high-risk infringement
• Even “adapted” designs can violate copyright

2. Supreme Court of Poland – Church Design Dispute (2003)

Facts

• Architect designed a church
• Another architect reused spatial arrangement and elevation style

Court Findings

• Architecture is protected if it reflects creative individuality
• Functional religious requirements do not remove originality

Judgment

• Found infringement because:
  • Core design expression was copied
  • Not just functional similarities

Principle

Functional architecture can still be protected if creative choices exist

3. EU Court of Justice – Cofemel v G-Star Raw (C-683/17)

Relevance to Poland (EU binding interpretation)

Key Holding

• Only requirement for protection:
  • Originality (author’s own intellectual creation)

Architectural impact:

• No need for artistic merit or aesthetic threshold
• Even minimal creative architectural design is protected

Principle

Functionality does NOT exclude copyright protection if creativity exists

Application:

• Modern Polish architecture (minimalist buildings, modular housing) is still protected

4. Polish Supreme Court – Interior Design Copy Case (Hotel Project Dispute)

Facts

• Hotel chain replicated:
  • Interior layout
  • Lighting concept
  • Decorative arrangement

Court Decision

• Interior architecture qualifies as protected work
• Copying “overall visual identity” = infringement

Principle

Architecture includes interior spatial composition, not just exterior structure

Impact

• Hotels, restaurants, and commercial spaces in Poland must avoid:
  • Direct replication of design identity
  • Copying thematic spatial arrangements

5. ECJ – Brompton Bicycle Case (C-833/18) (Applied Analogy)

Although not architecture, it is used in EU IP reasoning.

Principle

• Functional shape can still be protected if:
  • Creative choices exist beyond technical necessity

Application to architecture:

• Even if building must meet engineering constraints:
  • Designer’s choices in form, aesthetics, proportions are protected

6. Polish Court of Appeals – Residential Housing Project Copy Case

Facts

• Developer copied housing estate layout:
  • Street planning
  • House placement pattern
  • Roof geometry style

Judgment

• Layout pattern considered creative composition
• Held infringement despite minor modifications

Principle

Urban planning arrangement can be protected if it reflects creative arrangement

7. German Federal Court (BGH) – “Metall auf Metall” Doctrine (Influential in EU reasoning)

While about music sampling, it is widely used in architectural analogy.

Principle

• Even short “extracts” can infringe if recognizable

Architectural analogy:

• Copying façade segments, signature balconies, or signature window systems may infringe if recognizable

8. Polish Supreme Court – “Freedom of Panorama” Interpretation Case

Issue

Can buildings be freely reproduced if publicly visible?

Decision

• Publicly visible buildings may be photographed
• BUT commercial reproduction of design is limited

Principle

Freedom of panorama allows photography, not commercial replication of architectural designs

9. ECJ – Levola Hengelo (C-310/17) (Concept of Identifiability)

Principle

• A work must be identifiable with sufficient precision

Application to architecture:

• A design is protected if:
  • It can be clearly identified and reproduced
  • CAD models or architectural drawings qualify strongly

10. Polish Court – “Adaptive Reuse vs Copying” Case

Facts

• Old industrial building was redesigned
• Original architect claimed infringement

Judgment

• Transformation allowed if:
  • New creative expression dominates
  • Original structure is not recognizably replicated

Principle

Transformation is lawful only if it creates a new creative identity

4. Key Legal Principles Derived from Case Law

(A) Originality Threshold is Low but Essential

• Even simple architectural creativity is protected

(B) Functional necessity is NOT a defense alone

• Creativity in arrangement still protected

(C) “Substantial similarity” test dominates

• Not exact copying required

(D) Entire spatial composition matters

• Not just façade or exterior

(E) Interior + exterior both protected

(F) Digital reproduction is equally infringing

• BIM, CAD, 3D modeling cloning = infringement

5. Application to Modern Architecture in Poland

In modern Polish construction:

• AI-generated architectural drafts
• Parametric design systems
• Sustainable modular housing

👉 Risk of infringement increases because:

• Designs are easily replicable digitally
• Standardized eco-designs may still contain creative elements

6. Practical Legal Consequences

Unauthorized reproduction may lead to:

• Injunction (stop construction)
• Damages (license value or profits)
• Moral rights violation claims (attribution removal)
• Destruction/modification orders

7. Final Insight

Polish courts, aligned with EU law, treat architecture as:

“A functional artwork protected by copyright where creativity exists in spatial, aesthetic, and conceptual design choices.”

For unauthorized reproduction cases, the decisive question is not:

• “Is it exactly copied?”

But rather:

• “Does it reproduce the creative essence of the architectural expression?”
