One Hat One Hand

We had the opportunity to contribute to a true centrepiece, a feature designed to anchor the experience of arrival. From the chandelier design by @officeofthings and @onehatonehand , we were commissioned to 3D print the diffusion rings for the Hyatt Regency in Greenwich, Connecticut, working in close collaboration with the wider team. The result is an immersive, hospitality-driven installation, eight complex tubular rings forming a 4.6m diameter composition, suspended within the atrium. More than lighting, it acts as a spatial device, softening the scale, guiding the eye, and setting a calm, ambient tone for guests as they move through the space. Our role focused on developing the 3D printed diffusion components, including extensive design and engineering in collaboration with the team to ensure tight-fitting connections, precise assembly, and the desired quality of light diffusion. Using a 6-axis robotic printer, we introduced a custom algorithm that adapts layer heights to curvature, allowing for controlled, cantilevered geometries with both structural integrity and visual lightness. Material played a key role in the atmosphere. We developed a bespoke, fire-retardant translucent PLA in-house, tuned to diffuse light evenly and warmly, enhancing comfort while meeting strict hospitality and safety requirements. This is where architecture becomes experience, where material, light, and technology come together to shape how a space is felt, not just seen. If you are looking to create a distinctive feature for a hospitality environment, something that defines identity and elevates the guest experience, get in touch. #HospitalityDesign #HotelDesign #GuestExperience #FeatureLighting #StatementPiece #AtriumDesign #SpatialDesign #AtmosphereDesign #InteriorArchitecture #LuxuryInteriors #ArchitecturalLighting #LightingDesign #ParametricDesign #ComputationalDesign #3DPrintingArchitecture #RoboticFabrication #DigitalCraft #AdvancedManufacturing #CircularDesign #InnovativeMaterials #PLA #SustainableDesign #DesignInnovation #ExperientialDesign #DesignForHospitality

Mareas is a permanent public artwork situated at the pedestrian entrance of the James R. Herman Cruise Terminal Plaza at Pier 27. As the inaugural permanent archway along San Francisco’s Embarcadero waterfront, the sculpture was commissioned by the San Francisco Arts Commission in collaboration with the Port of San Francisco. @sf_port Upon receiving the invitation to propose a design for the waterfront, I observed a significant historical absence of the arch form within the public art discourse on the Embarcadero. The three primary existing permanent works in the vicinity are characterized by a specific phallic and red aesthetic and were exclusively created by male artists. As the first Mexican woman artist to be included in the permanent public art collection, I am honored to Diversify the conceptual and structural landscape and Include the OCEAN within the critical environmental dialogue. From a structural perspective, Mareas represents a significant fabrication achievement by @onehatonehand . The “wave” composition consists of three arches engineered with nine distinct radii; specifically, each arch transitions between three different radii. The project required machine-curving and subsequent hand-welding to achieve the intended design, as it lacked a singular reference point for guidance. To facilitate drilling into the curved, circular pipes, a ten-foot support structure was engineered to stabilize the machinery. Following the initial puncture, 231 holes were drilled, each accommodating a unique flat rectangular tile shifting in shape along the pipe to create an illusion of curvature using precise spacing. The three connecting pipes, while appearing perpendicular, are positioned at an 85-degree using a CNC five-axis laser to ensure a precise coup joint fit. If I lost you, you are not alone. All to say, arches are among the hardest structures to implement and require mathematical wizards. The apparent simplicity of the Mareas is technically deceptive, with zero tolerance for imperfections, any misalignment would be immediately discernible.

Help us support a vital Oakland community need. This will take just a few minutes of your time! Since 2013, Friends of Hoover Durant Public Library @fohdpl has been organizing to bring a library back to the Hoover-Durant, McClymonds, Pill Hill, Mosswood, Western Longfellow, and Clawson neighborhoods. This grassroots, volunteer-run nonprofit is vital to the culture, education, and welfare of our diverse communities. On April 14, 2026, the City of Oakland will hold a special meeting to review the purchase of the Community Market site for the Hoover Durant Branch Library. That is just seven days away. Visit our Linktree, grab the template, and send your letter today! Oakland's neighborhoods deserve this library, and your voice can help make it happen.
