Wallpaper - Diablo Dam

Our Diablo Dam wallpaper brings together the striking scale of civil engineering and the quiet atmosphere of the Pacific Northwest. Photographed by Alan Majchrowicz, the composition captures the sweeping concrete curve of the dam as it arches across calm green water, framed by misty evergreen hills and vintage lampposts along the crest. Tonal charcoal greys, soft misty whites, and muted forest greens create a cool, contemplative character across the wall. Printed made-to-measure on our PVC-free paper with a subtle surface texture, this architectural photograph brings depth and calm to an interior.

In the room

Because the motif relies on a strong horizontal sweep and a soft, misty background, we see this working particularly well on a wide, uninterrupted wall where the full curve of the dam can unfold. In a living room or a dedicated home study, placing this design behind a low sofa or a work desk lets the atmospheric tree line and rising fog remain completely visible. The cooler palette also suits a quiet bedroom setting, where the subdued contrast between the concrete structure and the surrounding pine forest creates a balanced, grounding backdrop. For a home library or reading den, the architectural rhythm brings an element of visual focus without feeling overly busy.

Styling it

To balance the cool, structural character of the photograph, we like pairing this wallpaper with elements that echo its period feel or introduce warm contrast:

• Bring in warm timber pieces, such as medium-toned walnut or teak, to soften the cool concrete greys and deep greens of the scenery.
• Incorporate vintage or mid-century lighting, especially fixtures featuring aged brass or matte black iron, which echo the historical street lamps along the crest of the dam.
• Keep large upholstery simple and structured in textured charcoal, slate grey, or deep forest green fabrics to anchor the room naturally.

Colour combinations

The palette within our design centres on charcoal grey, cool concrete stone, deep evergreen, and pale misty off-white. When choosing paint for adjacent walls, skirting, and ceilings, we suggest working with soft neutral greys or chalky off-whites that pull out the lighter tones in the fog. If you prefer a moodier, more enveloping space, a deep charcoal or a blackened pine green on surrounding joinery creates a handsome, cohesive frame around the wallpaper.
