Wallpaper - Treehouse Neighborhood Cool

Our Treehouse Neighborhood Cool wallpaper, created by Mairin Kareli, brings together an imaginative fantasy cityscape set high among towering trees. Ornate architectural elements with pointed rooftops and arched windows connect through winding bridges and pathways, surrounded by lush green foliage and swirling, mist-like layers. Rendered in a cool palette of sky blue, soft gray, and gentle green tones, the illustration balances fine ink-like linework with soft washes of color. Produced made-to-measure on PVC-free paper with a subtle paper texture, this wall mural introduces a world of storybook wonder while keeping the visual atmosphere light and composed.

In the room

We see this design working particularly well in spaces where storytelling and imagination feel at home, such as a children's bedroom, playroom, nursery, or teenage room. The vertical movement of the trees and towering buildings draws the eye upward, making it a great match for a feature wall behind a bed or low play furniture. Because the motif is rich with intricate bridges, roofs, and foliage, giving the design an uninterrupted wall allows the full fantasy landscape to unfold without key architectural details being hidden behind tall storage. In a home library or study, the cooler blue and gray background creates a quiet backdrop that feels thoughtful without overwhelming the room.

Styling it

To let the detailed linework of our mural wallpapers stand out, we suggest pairing the design with furniture that has clean, uncomplicated profiles. Simple painted furniture in off-white or muted slate harmonizes naturally with the cooler tones in the illustration. If you prefer natural wood, pale timbers like birch or light ash introduce warmth without competing with the soft green canopy. Keeping larger soft furnishings in solid, texture-rich fabrics rather than competing prints will give the detailed cityscape the visual space it deserves.

Colour combinations

The wallpaper is built on a foundation of sky blue, misty gray, and fresh leafy greens, grounded by fine darker architectural lines. When painting adjacent walls or woodwork, soft cloud grays, pale chalky whites, or gentle powder blues will create a seamless, cohesive look around the room. For an accent color in cushions, throws, or decorative details, deeper forest green or a quiet navy blue echoes the darker shadows in the foliage and structural details.
