Özet

Construction-oriented economic growth

strategies driven by neoliberal policies create

serious conflicts with sustainability principles. In

this context, it is important to examine the

relationship between the minimalist design

approach in housing production processes and

the United Nations Sustainable Development

Goals (SDGs). This study aims to identify the role

of minimalist design principles in sustainable

mass housing production and analyze their

contribution to the SDGs. The research is

structured through a multi-stage modeling

process based on a systematic literature review

and expert opinions. According to the findings,

“Functional Simplicity and Efficiency”, “Process

and Production Optimization” and “Human-

Centered Design” stand out as the most effective

criteria. The model showed particularly strong

relationships with SDG 11 (Sustainable Cities

and Communities) and SDG 12 (Responsible

Production and Consumption). This study

presents a strategic decision support model for

policy makers and practitioners by demonstrating

the multidimensional contributions of minimalist

approaches to sustainable international housing

design.

Introduction

In recent years, many countries have adopted

construction-oriented economic growth strategies

within the framework of neoliberal policies,

creating serious tensions with core sustainability

principles. Within this context, exploring the

structural relationship between minimalist design

principles and the United Nations Sustainable

Development Goals (SDGs) in housing

production processes is of critical importance for

advancing sustainable architectural practices.

The aim of this study is to determine the role of

minimalist design principles in the production of

sustainable mass housing, to measure their level

of contribution to the relevant SDG targets and to

put forward a multi-layered evaluation model.

Materials and Methods

The research was designed using a mixed-

methods strategy and conducted in five stages:

(1) a systematic literature review, (2)

development of a conceptual framework, (3) a

two-round Delphi process involving expert

opinions (n = 56), (4) criterion weighting using

Likert-Based Fuzzy AHP, and (5) validation of the

proposed model through Structural Equation

Modeling (SEM). The literature review enabled

the identification of 13 minimalist design

principles, which were then matched in detail with

all 17 SDGs and their 169 sub-targets to

construct a conceptual structure.

Results and Discussion

Data from the Delphi process demonstrated high

internal consistency (Cronbach's α = 0.968) and

strong factor structure (KMO = 0.849; variance

explained = 79.2%).

The FAHP results indicated that “Functional

Simplicity and Efficiency” (0.223), “Process and

Production Optimization” (0.197), and “Human-

Centered Design” (0.182) were the most heavily

weighted and impactful criteria. SEM analysis

confirmed the structural validity of the proposed

model, identifying significant and direct

relationships between minimalist design

principles and SDG 11 (Sustainable Cities and

Communities) as well as SDG 12 (Responsible

Consumption and Production) (m9.1–m9.3: r =

0.89, p < 0.001). The model’s fit indices were

found to be within acceptable ranges (CFI =

0.865, RMSEA = 0.132, SRMR ≈ 0.08).

Conclusion

This study systematically reveals the

multidimensional impacts of minimalist

approaches on sustainability-oriented housing

design and offers an original decision-support

model. The findings are a strategic reference

source for designers, policy makers and

practitioners who prioritise the principle of

sustainability in the international housing

production process.
