Here’s a look at the mix of materials we carefully curated for the resident’s lounge in one of our recent client projects.

The range includes soft light stucco and stone tiles, complemented by natural travertine flooring that flows seamlessly throughout the entire space. The accent feature wall in the pantry combines a ceramic tile backsplash with a textured patinized (oxidized) copper finish, adding depth and character.

Each material was chosen not only for its aesthetic appeal but also to evoke a calm, timeless atmosphere that feels both welcoming and sophisticated.

What’s your favorite material from this palette?

Now halfway through 2025, we’re seeing a clear shift in interior design—toward warmth, texture, and nature-inspired tones. This year’s key colors are Terracotta, Sand, Olive, and Dust.

They’re warm, textural, and deeply connected to how we want to feel in our spaces—calm, comfortable, and rooted.

Four standout hues define this movement: Terracotta, Sand, Olive, and Dust. Each brings a distinct personality and material story, yet all share a quiet elegance that allows them to work beautifully together—creating interiors that feel both current and timeless..
