"An overhead view of a colorful outdoor installation featuring a central white seating area with a tree in the middle, surrounded by geometric patterned flooring in vibrant shades of purple, pink, blue, and orange. The structure is enclosed by wooden frames with colorful translucent panels and intricate designs. A person is sitting on the seating area, and another is walking nearby, adding a sense of interaction and scale."
A large pile of discarded wooden materials, including broken pallets, planks, and furniture, scattered in an open area under a cloudy sky. The debris appears to be a mix of construction waste and other wood scraps, with some colored panels and scattered items visible amidst the pile. Trees can be seen in the background

Why create an interior that is destined to be waste? 

"For years, I built interiors, only to see their temporary nature turn them into waste. My mission now is to ensure that interiors no longer are wasted."

Empowering you to make a sustainable choice through color.

Our clients say

‘Marije Remigius joined us in an inspiring and relevant campfire session to exchange ideas about the sustainability of materials in the interior design industry. Involved us in the complex exercise of a life Cycle Assessment (LCA).She introduce dus to her method for labelling the sustainability of these materials and discussed broader issues around circularity with us.”

“In opdracht van het Scheepvaartmuseum ontwikkelden we voor Kadir van Lohuizens tentoonstelling 'Food for Thought' een toolkit die musea wereldwijd helpt deze tentoonstelling lokaal en duurzaam op te bouwen. Dankzij Inter Matters tool biedt de toolkit helder advies over duurzame materialen, zodat musea eenvoudig verantwoorde keuzes kunnen maken.”

Maaike Kleijn, Projectmanager, Lmnop.works

“Marije Remigius inspireert met een tastbare en leervolle lezing. Concrete voorstellen over meetbaarheid van LCA en de impact van materialen op ons milieu. Met de meegebrachte stalen gaf ze een visueel en tatsbaar beeld van de mogelijkheden van biobased materialen. En we zullen niet snel vergeten: “Een ronde vorm is niet circulair.”
