Biltmore – Casita & ADU Additions for Elegant Expanded Living

In the prestigious Biltmore area of Phoenix, adding a casita or accessory dwelling unit (ADU) is more than just gaining extra space—it’s about expanding your lifestyle with grace, flexibility, and architectural harmony. Whether you’re building a private guest retreat, a multi-generational suite, or a home office sanctuary, Homework Remodels designs and builds luxury casitas and ADUs that seamlessly integrate with your existing home.

We’ve helped homeowners throughout Arizona Biltmore Estates, Biltmore Greens, and Taliverde unlock the potential of their properties with detached or semi-attached structures that offer privacy, comfort, and long-term value. Our design-build process ensures that every detail—from roofing profiles to window placement—is carefully tailored to your home and lot.

What Is a Casita or ADU?

Casitas and ADUs (Accessory Dwelling Units) are self-contained living spaces built on the same lot as the main home. They typically include:

  • A bedroom or flexible studio space
  • A bathroom
  • A small kitchen or kitchenette
  • A separate entrance
  • Optional living/dining area
  • Full utility connections and climate control

In Biltmore, these additions often serve as:

  • Guest quarters for visiting family and friends
  • Private suites for aging parents or adult children
  • High-end rental units (where allowed)
  • Home offices or studios with residential comfort
  • Poolside pavilions or cabana-style retreats

Why Biltmore Homeowners Choose Casita Additions

The Biltmore area offers large lots, lush landscaping, and architectural variety—making it an ideal setting for thoughtful, elegant expansions. A well-designed casita or ADU:

  • Enhances property value and market appeal
  • Provides privacy for guests or extended family
  • Maintains the beauty and integrity of the main home
  • Supports changing needs without requiring a move
  • Can be customized with luxury finishes, built-ins, and smart home systems

Our clients in Biltmore aren’t looking for cookie-cutter solutions. They want their new space to reflect the same design sensibility as the rest of the home—and we deliver exactly that.

Casitas and ADUs We Build in Biltmore

Each casita or ADU we create is fully customized. Common layouts and features include:

  • Detached guest houses with a full bathroom and kitchenette
  • Poolside casitas with sliding doors and covered patios
  • In-law suites with private entrances and ADA-friendly layouts
  • Detached home offices or studios with built-in cabinetry and sound insulation
  • Multi-purpose ADUs designed for future flexibility

We work with the architectural language of your home—whether it’s Spanish Colonial, contemporary, or transitional—to create a structure that feels cohesive and permanent.

Design-Build Remodeling for Casitas & ADUs

Our design-build system streamlines every phase of your addition, from initial ideas to handing you the keys. This means you won’t have to coordinate multiple professionals—we provide a single team that designs, engineers, permits, and builds your new space.

Our process includes:

  • Site evaluation and zoning review
  • Custom floorplan design based on your goals
  • Matching exterior materials and architectural style
  • Full-service permitting with the City of Phoenix
  • Turnkey construction with expert supervision
  • Interior finishes curated for comfort and elegance

We’ll help you navigate questions like:

  • Where on the property should the casita go?
  • Should it be attached, detached, or semi-connected?
  • Will it require a new sewer tap or connect to the existing line?
  • How should it be accessed for privacy?

Permits, Zoning, and Biltmore Neighborhood Considerations

Every casita or ADU project must comply with local codes, setbacks, utility access rules, and neighborhood-specific requirements. In the Biltmore area, some homes are subject to HOA oversight or covenants that dictate architectural controls.

Homework Remodels manages:

  • All Phoenix city permitting
  • Compliance with neighborhood and historic guidelines
  • Coordination with utility providers
  • Scheduling of all required inspections

We handle the red tape so you can focus on the vision.

Luxury Finishes for Discerning Homeowners

Just because it’s an ADU doesn’t mean it should feel like an afterthought. Our Biltmore casitas and guest suites are built to the same standards as the main home. That includes:

  • Quartz and natural stone countertops
  • Designer lighting and hardware
  • Custom cabinetry and built-ins
  • Energy-efficient windows and climate control
  • Smooth drywall, premium flooring, and detailed trim
  • Smart locks, thermostats, and security integration

We don’t just build boxes—we build beautiful, functional living spaces that fit seamlessly into high-end residential settings.

Casitas vs. Guest Houses vs. ADUs – What’s the Difference?

While terms often overlap, here’s how we define them for clarity:

  • Casita: A guest-focused structure designed for comfort and hosting
  • Guest House: Often more spacious and fully outfitted for long-term living
  • ADU: A legal term referring to a secondary residential unit; can include both of the above, depending on zoning

In Biltmore, we typically use “casita” or “guest house” when referring to structures that reflect the luxurious lifestyle of the neighborhood, even if they qualify legally as ADUs.
