In a city home to global tech giants, a workspace should be more than just a desk in a corner. We design home office additions in Redmond featuring sound-insulated walls, integrated fiber-optic wiring, and "smart glass" that adjusts for glare during video calls. By creating a dedicated, high-performance workspace, we help you draw a clear line between professional productivity and your personal sanctuary.
Redmond's 2026 zoning updates have opened new doors for property owners. We specialize in navigating the updated Neighborhood Residential (NR) codes, which now offer increased flexibility for adding square footage and even multiple dwelling units on a single lot. We help you maximize your property's potential while ensuring compliance with Redmond’s latest affordability and density requirements, turning your backyard or existing footprint into a high-value asset.
Redmond residents value their connection to the outdoors. Our sunroom and "four-season" additions utilize high-efficiency glazing and natural materials like slate and white oak to create a grounding, restorative space. These additions are designed to capture the limited winter light while staying cool in the summer, providing a year-round retreat that feels like a daily escape into nature without leaving your home.
Transform your primary bedroom into a private spa retreat. Our luxury additions often include "wellness wings" equipped with infrared saunas, steam showers, and aromatherapy-integrated ventilation. In 2026, Redmond homeowners are prioritizing health; we build these spaces using non-toxic, organic materials and advanced HEPA filtration, ensuring your new suite supports both your comfort and your long-term well-being.
As family dynamics shift, "Gensuites" and Accessory Dwelling Units (ADUs) have become a hallmark of Redmond home expansion. We design detached or attached additions that provide complete independence—including private kitchenettes and entrances—while maintaining architectural harmony with your main residence. These spaces are perfect for aging parents, adult children, or as a premium rental opportunity to offset your mortgage.
Redmond’s building environment is constantly evolving, with new 2026 amendments affecting everything from fence heights to noise standards and environmental impact. As your local experts, we handle the entire regulatory process, including SEPA checklists and tree retention plans. We ensure your project stays on schedule by coordinating directly with the City of Redmond’s Technical Committee, moving you from blueprint to "sheetrock-ready" with zero stress.



Need another bedroom, more living room space, or an extended office? We design and build room expansions that blend in perfectly with your current home. Our focus is to make every inch of space useful while matching your family’s lifestyle.
When your lot does not allow outward expansion, we help you build upward. Our second-story designs add valuable space while maintaining your home’s style and structure.
Unused garages can be turned into functional living areas. We remodel them into home gyms, guest rooms, or offices, complete with insulation, flooring, and lighting for comfort.
If you need only a few more feet in your kitchen, dining room, or bedroom, a bump-out addition is a cost-effective solution. It provides extra room without a full renovation
Bring more natural light indoors with a sunroom or an enclosed patio. These spaces are perfect for relaxing, reading, or entertaining while enjoying comfort throughout the year.
