Modular Shelving System

Project Context

This project was developed as part of the Product and Form I & II coursework at Aalto University. The brief required using one casted material and one solid material to design a modular shelving system. As further restrictions, materials were limited to concrete, aluminum glass, and wood, prompting exploration of innovative approaches. I chose concrete as the cast material, but I aimed to experiment with a bio-based mix to align the project with sustainable design goals.

Material Exploration & Innovation

To address the environmental impact of traditional concrete, I developed a sustainable mix by incorporating spent coffee grounds and fibers from used coffee filters as filler materials. This not only reduced the weight and carbon footprint of the concrete. The coffee-based fillers reduced the CO2 emissions of the concrete required per unit from 4.17 kg to 2.9 kg—a significant improvement in sustainability.

The second material used in the shelving system was two-way airplane veneer, which added durability and a refined aesthetic finish. This material combination emphasized lightweight, modularity, and eco-conscious design.

Refining the Design Through Experimentation

Initial experiments with eco-concrete led to adjustments in the mix to achieve optimal hardening and structural performance. Hand- and CNC-crafted molds were refined to ensure a seamless fit, showcasing adaptability and problem-solving throughout the process.

The modular shelving system consists of veneer-lined eco-concrete panels that can be stacked and secured with a tourniquet strap. The veneer provides a smooth, elegant finish that contrasts with the raw texture of the ecoconcrete. An optional wooden shelf insert was added to enhance usability by supporting square objects, further demonstrating the system’s versatility.
