Elevating Your Seattle Home
From the historic, tree-lined streets of Queen Anne and Capitol Hill to the vibrant, walkable neighborhoods of Ballard and the sweeping coastal views of West Seattle, this city offers an unmatched urban lifestyle. Whether you own a century-old Craftsman, a mid-century hillside property, or a classic Seattle box home, your house should serve as a luxurious, comfortable sanctuary that maximizes every square inch of its urban footprint.
​
However, the historic homes that give Seattle its incredible architectural soul often feature highly segmented, closed-off floor plans, outdated plumbing, and cramped spaces that no longer fit the way modern families live and entertain. At Fusion Builders LLC, we specialize in high-end, transformative renovations for discerning urban homeowners. By safely tearing down restrictive walls, upgrading outdated systems, and designing smart, open-concept layouts, we transform dated houses into spectacular, modern estates—all while preserving the historic charm you fell in love with. From the first design sketch to the final SDCI inspection, we manage the heavy lifting so you can simply enjoy the transformation.
Our Custom Remodeling Services in Seattle, WA
Historic & Craftsman Modernizations
Seattle boasts some of the finest historic architecture in the state, but century-old Craftsman, Tudor, and Foursquare homes require highly engineered, sensitive updates. We specialize in modernizing your home's layout, electrical, and plumbing while perfectly preserving its iconic architectural character. We integrate original millwork and historic charm with top-tier modern, open-concept luxury.
Open-Concept Kitchens
In a city where square footage is at a premium, efficient space planning is everything. We specialize in removing restrictive load-bearing walls in older Seattle floor plans to create sprawling, open-concept layouts that connect your cooking, dining, and living spaces. Our team installs expansive custom islands, beautiful quartz countertops, and premium cabinetry built to maximize storage and elevate your daily routine.
Custom DADUs & Backyard Cottages
To combat urban density, the City of Seattle has heavily relaxed its zoning laws to encourage Detached Accessory Dwelling Units (DADUs). Building a backyard cottage or finishing a basement apartment is an incredibly lucrative way to generate high-value rental income or create a multi-generational suite. We safely and seamlessly handle the entire build, maximizing your lot's potential.
View Decks & Outdoor Living
Whether you are looking out over the Puget Sound, Lake Union, or the downtown skyline, your Seattle view is your property's greatest asset. We design and build premium outdoor living spaces tailored specifically to tight urban lots and steep hillsides. From multi-level composite decking with frameless glass railings to rooftop decks and covered patios, we create the ultimate environment for year-round entertaining.
Navigating Seattle Permitting (SDCI) & Steep Slopes (ECA)
Major renovations in Seattle require a local contractor who knows exactly how to navigate the Seattle Department of Construction and Inspections (SDCI) to prevent months of costly delays.
​
Whether we are securing structural permits to safely remove load-bearing walls in a 1910s Ballard home, managing complex geotechnical engineering for a new view deck in a steep-slope Environmentally Critical Area (ECA) in Magnolia, or navigating the latest DADU zoning codes in West Seattle, Fusion Builders LLC handles the entire process. We manage all architectural drafting, permit submissions, and local inspections, ensuring your luxury project is fully compliant and stays on schedule.

Frequently Asked Questions: Seattle Remodeling
Can you safely open up the floor plan in a century-old Seattle home?
Absolutely. Older homes in neighborhoods like Capitol Hill, Queen Anne, and Ballard were built with highly segmented, closed-off rooms that block natural light. We work closely with licensed structural engineers to safely remove these load-bearing walls, address old lath-and-plaster, and install hidden support beams (flush beams). This transforms your historic home into a sweeping, modern, open-concept living area while preserving its original architectural soul.
Is it easy to build a Detached ADU (DADU) in Seattle?
Yes! The City of Seattle has implemented some of the most progressive and accommodating ADU laws in the country. Minimum lot size requirements have been reduced, parking requirements have been removed, and you can now build both an attached ADU and a detached DADU on the same lot. We will assess your specific lot's zoning and utility connections to ensure a DADU is viable before designing the perfect custom guest house or rental property.
Do I need special engineering to build a deck or addition on a steep slope?
If your property is located on a hillside in West Seattle, Magnolia, or Queen Anne, there is a high probability it falls within an Environmentally Critical Area (ECA). Any structural additions or decks in an ECA require specialized geotechnical engineering to ensure soil stability and prevent landslides. We handle this entire specialized engineering and permitting process for you, ensuring your new build is safe, stunning, and fully SDCI-compliant.
