So, Patricia, how did Matterpieces begin?
‘We - meaning me and co-founder, Luís Lima - were living in Vienna, working as architects on social housing projects, among others. We were already deeply aware of the industry’s impact and passionate about reshaping construction for the better. Then came a project to design a vegan restaurant. The client was all about sustainability, constantly pushing us to find the most eco-friendly solutions and materials for renovating the space.
During demolition, we watched walls come down, piles of waste forming - and at the same time, we were searching for sustainable materials. It felt like a complete contradiction: we needed materials, yet we were surrounded by them. But back then, we didn’t have a strategy to reuse them.
That moment planted a seed. Shortly after, just before the pandemic, we moved back to Portugal, where we were both born. Suddenly, in between houses, jobs, and lockdowns, we had time to experiment. Could we make waste beautiful and turn debris into something desirable?
We started making samples of new building materials - in garages, in our parents’ gardens, and alongside friends in material engineering. It was really hardcore, doing everything manually, but the results were amazing. One of our first breakthroughs was repurposing cement, old ceramic and roof tiles into sleek, terrazzo-like surfaces. But then came the big question: How do we scale this up from the kilos we were now doing by hand to the tons required when constructing or renovating buildings? We needed to up our game: talk with the demolition and waste management companies.
