# Modern Seattle Floating Home Blends Coastal Style with Waterborne Engineering A custom-built residence in Eastlake redefines waterfront living through precise structural design. - **Source:** [Design MilkArchitecture, Architectural Designs, and House Designs | Design Milk](https://brifing.si/source/5d8362a6-0dbb-41cc-9b0e-4e8cac0c9318) - **Published:** 2026-11-04 - **Topic:** [culture](https://brifing.si/c/culture) - **Original article:** - **On Brifing:** https://brifing.si/s/85c56e52-b7d6-455f-8afb-f7fe154428f5 ## Unique Waterborne Construction Process The residence was built entirely on a concrete float at the Dyna Builders docks in Ballard. Following completion, the structure was towed across the lake to its permanent slip in the Eastlake community. This specialized construction method allowed for better access to equipment while minimizing disruption to the neighboring floating-home residents. ## Design Influences and Aesthetic Goals Designed by Hoshide Wanzer Architects, the 2,123-square-foot home merges Nantucket coastal charm with Pacific Northwest architectural lines. Ren Chandler, president of Dyna Builders, noted that the design avoids overt nautical clichés. Instead, it utilizes a palette of blues, greens, and warm neutrals, paired with weathered wood and tactile finishes throughout. ## Structural Engineering for Floating Foundations Building on water requires a distinct approach compared to solid ground construction. The concrete float serves as a stable foundation while housing necessary utilities. Engineers had to prioritize weight distribution and structural integrity from the start, as these factors directly influenced decisions regarding interior finishes and the overall structural system used. ## Open Living and Waterfront Connectivity The main level features an open floor plan oriented toward Lake Union, anchored by a central chimney spine. Fleetwood glass doors slide into wall pockets, allowing the kitchen, dining, and living areas to extend seamlessly onto the waterfront deck. This layout creates a direct, unobstructed connection between the interior and the lake. ## Durability in Damp Climates The home utilizes resilient materials to withstand the Pacific Northwest's moisture. Features include yakisugi siding, cork-rubber flooring, and stain-resistant cabinetry. A dedicated mudroom with both interior and exterior showers provides a practical transition space for residents returning from the water, ensuring the home remains protected against wet gear and frequent daily use. ## Custom Craftsmanship and Interior Details The interior showcases bespoke elements, such as a sculptural wood partition in the dressing area with undulating slats. Custom built-in bunks in the secondary bedrooms feature internal steel framing fabricated in Dyna’s own metal shop. Additionally, illuminated resin panels line the stairwell, providing a subtle nautical reference while casting soft, ambient light. ## Privacy Within Dense Communities Living in the closely spaced Eastlake floating-home community necessitates careful attention to privacy. The architects utilized strategically positioned ribbon windows and layered window treatments to shield the interior from neighbors. These design choices ensure that the residents maintain a sense of seclusion without sacrificing the abundance of natural light throughout the home. ## Balancing Engineering and Comfort The project represents a successful marriage of technical precision and everyday comfort. While the home relies on complex engineering for stability and moisture control, these systems remain largely invisible to the occupants. Ultimately, the residence demonstrates how unconventional, water-based living can feel entirely natural through thoughtful design and high-quality material selection. ## Sources covering this story - https://design-milk.com/seattle-floating-home-hoshide-wanzer/ — --- _Summary written by Brifing from the original reporting.
