The best way to add warmth in minimalist interiors like Troye Sivan’s is through layering organic textures and warm neutral tones. Incorporate tactile materials such as linen curtains, plaster walls, natural stone ledges, and wooden furniture to introduce subtle sensory richness. Use a disciplined palette of warm beiges and soft greys that complement natural light rather than stark whites or cool tones. Strategic lighting with warm bulbs and hidden sources enhances coziness without clutter. This layered approach adds depth and personality while maintaining minimalist restraint, ensuring the space feels lived-in and inviting rather than cold or sparse. It balances modern glamour with intimate comfort perfectly.
