# Bio-based PLA+ Switch Covers Redefine Interior Aesthetics Kovr Studio's modular covers seamlessly blend switches into designed interiors. - **Source:** [design archives | designboom | architecture & design magazine](https://brifing.si/source/11868f8d-1e20-41ac-bc2d-8c5af32d721b) - **Published:** 2026-09-04 - **Topic:** [Design & UX](https://brifing.si/c/design) - **Original article:** - **On Brifing:** https://brifing.si/s/f8d24257-43fd-40cd-a602-a84ab9a6eb1d ## The Problem with Standard Switches Traditional white switch plates create visual interruptions in carefully designed interiors, often clashing with painted or wallpapered surfaces. These overlooked elements disrupt the harmony of interior spaces. Kovr Studio identified this design gap where functional necessities compromise aesthetic integrity. The studio's solution maintains functionality while elevating switch plates to design elements. ## Modular Design Solution Kovr's innovative covers transform existing switches without tools or adhesives, installing in seconds. The modular system allows homeowners to update switch aesthetics as interior styles evolve. This approach combines practicality with design flexibility, offering temporary or permanent solutions. The covers work with standard switch configurations while providing customization options. ## Sustainable Material Choice The covers use PLA+, a corn starch-based bioplastic selected for strength and flexibility. This material withstands repeated installation/removal without losing integrity, making it ideal for temporary design solutions. The bio-based plastic aligns with sustainable design principles, reducing reliance on petroleum-based materials. Kovr's material choice reflects growing demand for eco-conscious interior products. ## Precision Digital Fabrication Each cover undergoes digital fabrication in Kovr's Lille workshop, combining technology with hand-finishing. This hybrid production ensures consistency while allowing individual refinement. Digital tools enable precise geometries that fit standard switches perfectly. The process balances scalability with artisanal quality, typical of contemporary design manufacturing. ## Design Integration The covers introduce a new visual layer that integrates switches into surrounding surfaces. Rather than hiding switches, they transform them into intentional design features. This approach treats small architectural details as elements of interior composition. The solution demonstrates how functional necessities can enhance rather than compromise design. ## User Experience The installation process requires no technical skills - users simply snap covers on existing switches. This accessibility makes design upgrades available to renters and homeowners alike. The reversible solution empowers non-permanent interior customization. Kovr's design thinking extends beyond aesthetics to practical usability considerations. ## Market Position Positioned at the intersection of interior design and functional hardware, Kovr fills a niche market gap. The product appeals to design-conscious consumers and professionals seeking cohesive interiors. With growing interest in customizable living spaces, such solutions gain commercial relevance. The studio's focus on overlooked elements demonstrates innovative product thinking. ## Design Industry Impact Kovr's approach exemplifies how small details can transform interior experiences. The project challenges conventional perceptions of functional elements in design spaces. As attention to detail becomes increasingly valued, such innovations gain significance. This case study shows how product design can elevate everyday interactions with our environments. ## Sources covering this story - https://www.designboom.com/design/playful-covers-bio-based-pla-conventional-light-switch-kovr-studio/ — --- _Summary written by Brifing from the original reporting.
