Radical Circularity in Architecture and Design: Materials, Digitization, and Key Cases

Applied Circular Economy: From Theory to Built Space

The construction and interior design sector is one of the main waste generators. However, the rise of the circular economy is shifting perspectives: it promotes closed loops of use, reuse, repair, and recycling of materials, enhanced by digitization and a new creative mindset. In this guide, we dive into practices, technologies, and examples that allow moving from talk to action, boosting the commercial and environmental value of your projects.

Why Bet on Circularity Today?

Currently, according to the UN, the built environment consumes over 40% of energy and generates one-third of global waste. Without circular models, we would continue with a linear economy: extract, use, and discard. Embracing the circle reduces environmental impact, increases efficiency, and creates inspiring, resilient spaces.

Pillars of Material and Digital Circularity

A comprehensive circular approach requires:

• Selecting materials with low carbon footprint, certified origin, and maximum durability.
• Designing for disassembly and reuse (design for disassembly).
• Integrating digital tracing and modeling systems: BIM, digital twins, AI, and life cycle analysis help manage resources and prevent waste.
• Promoting onsite reuse and selective collection of valuable elements.
• Using digitization to plan, audit, and document the full cycle from design to deconstruction. See study at ScienceDirect.

Digitization as an Accelerator for Circular Design

Technologies such as BIM, AI, and material databases enable planning an efficient and profitable circular economy. For example, digital modeling platforms make it possible to identify reusable elements in renovation projects before demolition, maximizing onsite reuse and economic feasibility.

Moreover, digitization facilitates cycles where waste is identified and managed as resources in new value chains, as summarized in the academic report from CityU (PDF).

Essential Criteria for Selecting Materials and Systems

To ensure genuine circularity —not greenwashing— we need to consider these practical and measurable points:

• Certification: Use materials with EPD (Environmental Product Declaration) or trusted labels (FSC, Cradle to Cradle, GRS, PEFC, etc.).
• Modular flexibility: Prioritize systems that can be easily disassembled and relocated by space or function.
• Recycled and recyclable materials: Favor finishes produced locally or with recycled components and ensure they are recyclable or compostable at the end of life.
• Durability, reparability, and low maintenance: Prefer solutions with extended warranties and local access to repair parts.

The key lies in measuring, comparing, and transparently justifying your material selection aligned with the project.

Current Practices and Examples: Real Circularity in Action

1. Onsite reuse: Landscaping and sustainable construction are progressing by prioritizing the use of existing materials (stone, tiles, wood, structures). A flagship example is the modular redesign of hole 16 at the WM Phoenix Open, where the structure is 100% reusable, disassemblable, and reconfigurable year after year to reduce waste and logistics.

2. Modular commercial spaces: Major brands and retailers are shifting to detachable stands and corners, with furniture and panels that move between fairs or change format per season. This approach, besides cutting costs and time, enables systematic material inventories in digital platforms to facilitate recovery and updates year after year.

3. Circular residential: In urban home renovations, the trend is to maximize existing assets by restoring doors, floors, and furniture which, with proper treatment, can have a second or third life. By adding digital resources —comparative 3D models, local material banks, and traceability criteria— it’s possible to demonstrate positive impact to clients and justify investments.

4. New materials: The world of eco-friendly textiles and recycled composite materials is expanding annually. Formaldehyde-free resins, certified recycled fibers, and disassemblable composites—in furniture, panels, and finishes—are now stars in international catalogs and only require awareness and information to apply in regional markets.

5. Landscaping and green infrastructure: Use of treated natural materials, recovered furniture, and recyclable pavements alongside cutting-edge drainage solutions (SUDS, rain gardens, etc.) create resilient environments. Check recent ASLA explorations at The Dirt.

Realistic Perspective: Current Challenges and Latent Opportunities

Many professionals fear that incorporating circularity will increase costs, delay deliveries, or require overly technical knowledge. My personal experience, both in architectural firms and alongside manufacturers, proves otherwise: the more transparent and digital the process is—material banks, documentation, digital checklists—the easier it is to engage the end client and offer tangible, “sellable” added value. The main barrier is cultural and commercial: there is a lack of applicable information and tools with user-friendly interfaces. That’s why initiatives like transparency catalogs or increasingly friendly collaborative selection platforms are key to speeding up adoption.

Concrete Actions for Your Next Circular Project

1. Integrate circularity criteria from the start in your design brief and budget. Include key questions about disassembly and reuse possibilities, and specify material sources with traceability. 2. Use collaborative digital tools to model not only aesthetics but also the useful life and circular management of each element. A quick test: do you already have a digital inventory of your existing materials? 3. Prioritize suppliers and products that allow easy renewal, repair, and remanufacturing (ask if the system already provides standard parts or modules for future changes). 4. Measure and report results: track how much material you avoided turning into waste, how much energy/water you saved, and how this affects the perceived asset value. 5. Rely on certificates, labels, and visual communication tools that tell the circular story to your client (infographics, QR codes, catalogs, interpretive 3D modeling).

Strengthen Your Differentiator with Intelligent Visual Technology

Use advanced visualization engines to show before/after circular scenarios, material variants, and disassembly routes. Digital visual tools, such as parametric modeling for modular layouts or virtual staging of reused furniture, not only help sell the concept better but also facilitate quick decisions, minimize error risks, and turn circularity into a commercial argument, not just an ethical gesture.

Dig deeper with other blog resources: learn about certifications, materials, advanced visualization, and how to argue your circular added value to developers, brands, and end clients. And if you want to speed up your idea visualization and layout process for circular projects, explore how the solutions from Deptho and Redesign enable you to visualize, convince, and document your sustainable proposal with maximum ease.

Conclusion: Turning Circular Challenges Into Innovation and Business Opportunities

Circularity is no longer just an ethical requirement. Today it is a unique source of value, savings, and resilience. Architects, interior designers, agents, and brands can transform their processes now by combining circular criteria and materials with powerful visual digitization. The key is to argue, measure, and communicate—with support and creativity. The next revolution in the sector will be circular or it won’t be.
