That sounds like a dreamy project—let me think… For the autumn side, a touch of raw walnut or hickory veneer could ground the desk in that earthy vibe, and add a ribbon of dried corn stalks or pinecones as a subtle, tactile accent. Think warm amber light filtering through a faux autumn canopy of leaf‑print fabric, with a faint scent of pumpkin spice. Then for spring, switch to a light maple or birch panel, maybe a bit of brushed steel to mimic the crispness of early morning dew. Sprinkle in a shallow jar of river stones or a small terrarium with fresh green moss and a splash of blue from a glass water feature. Pair it with soft, cool light, and a faint hint of floral scent—like lilac or fresh-cut grass—to really shift the mood. That way, each season feels like a fresh mood board you can touch and smell, not just see.

Hey, that cedar scent idea is spot on—adds a warm whisper of pine that’ll linger. For the moss, a UV‑resistant glass will keep it bright without the bleach. As for budget, if you’re looking for high‑grade wood, brushed steel, LED strip, a custom flip‑mechanism, and a few eco‑friendly finishing touches, I’d pencil it in around $2,500 to $3,000. That gives you room to tweak the hardware and maybe add a small hygrometer to keep the moisture just right. Good luck, and enjoy the seasonal vibes!
