What Goes Into a Quality Garage Conversion or ADU Build
Building a successful ADU involves multiple construction phases, each requiring careful planning and skilled execution. Leonard Garage Conversion handles every aspect of the build process, including:
- Foundation: Often overlooked, the foundation is one of the most critical components of any ADU. It supports the entire framing structure and acts as an anchor between the walls, ceilings, and the ground below.
- Framing: This is where the garage conversion begins to take shape. Framing brings blueprints to life and supports all drywall, doors, windows, and roofing elements.
- Roofing: A properly installed roof provides the top layer of protection for the ADU, guarding against the elements while also contributing to insulation, safety, and privacy.
- Insulation: Good insulation keeps the interior comfortable year-round, protecting against cold in winter and heat in summer. It also reduces noise pollution and improves energy efficiency.
- Flooring: The right flooring provides structural support while enhancing the overall feel of the space. It must withstand moisture, heat, and sound, creating a welcoming and durable environment.
- Drywall: Drywall seals the interior from dust, insects, and outside air, making it easier to regulate temperature. It is quick to install, easy to paint, and can be shaped to fit arches or curved areas.
- Windows & Doors: Carefully planned windows and doors add visual appeal, provide natural light and ventilation, and contribute significantly to the overall design and function of the ADU.
- Painting: Beyond aesthetics, exterior and interior painting protects surfaces from UV rays, mold, wind, stains, pests, and chemical damage, extending the life of the structure.
Each of these elements is handled with precision and attention to detail, ensuring that every granny flat, in-law suite, or detached ADU they build meets the highest industry standards.
