  • Accessory Dwelling units

    Accessory Dwelling Units (ADUs) are an innovative solution for homeowners looking to expand their living space on a single-family residential lot. These secondary housing units can be detached, attached, or converted from existing structures, offering lots of flexibility. As the demand for affordable housing and sustainable living continues to rise, ADUs have become a popular choice for creating custom homes catering to diverse needs. Whether you’re looking to accommodate extended family, generate rental income, or simply add more space, ADUs provide a practical and efficient way to enhance your property.

    Our commitment to sustainable building practices is unwavering at Hygge Haus Design Build. We believe that creating energy-efficient homes is not only beneficial for the environment but also for the well-being of our homeowners. Our designs incorporate advanced energy-saving technologies, such as solar-powered systems and Zero Energy Ready homes, ensuring that each home we build is both eco-friendly and cost-effective. Additionally, our homes meet the stringent standards of EPA Indoor airPLUS, providing healthier indoor air quality. By integrating sustainable materials and techniques into every project, we aim to build a better future for our communities and the planet.

General Contracting

How it works

  • 1. Start the Conversation

    We begin with an in-person walkthrough and a conversation about your goals, style, and vision. From this, we build a clear design agreement and budget direction. We’ll also conduct a feasibility study to uncover any build challenges early on.

  • 2. Design & Planning

    In this phase, we collaborate with our architect, designer, and trade partners to bring your vision to life. We create sketches, material selections, and a full project timeline — all tailored to your lifestyle and goals.

  • 3. Finalize Budget & Construction Agreement

    Once the design is in place and selections are made, we finalize the scope of work and sign the construction agreement. At this point, we prepare for permits and get everything ready to build.

  • 4. Build Phase

    Our production team handles everything from permitting to final walk-throughs. We manage the process daily, maintain a clean site, and keep you involved with regular updates and walkthroughs. You're always in the loop.

  • 5. Warranty & Project Closeout

    Before handing over the keys, we conduct a detailed walkthrough and create a final punch list. Every home comes with a 3-year warranty, including check-ins at 30 days, 90 days, and 1 year. You'll also receive the Hygge Haus Handbook — your guide to life in your new home.
