Mid-Century Modern Guest House Additions

Guest House Additions for Mid-Century Modern Homes

Mid-century modern homes are renowned for their clarity of design, characterized by clean lines, intentional proportions, and a sense of openness that seamlessly integrates function and form. When it comes to adding a guest house or casita to one of these homes, that same thoughtful design philosophy should guide every detail.

At Homework Remodels, we specialize in design-build remodeling for mid-century modern homes, including the careful planning and construction of guesthouses, casitas, and ADUs (Accessory Dwelling Units). Whether your home is in Arcadia Lite, Paradise Gardens, Windemere, or another MCM neighborhood in Phoenix, we can help you expand in a way that looks and feels like it was always meant to be there.

Why Homeowners Add Guest Houses to MCM Homes

Mid-century homes were often modest in size—but built on generous lots. That combination makes them perfect candidates for architectural additions that:

  • House extended family or guests
  • Provide private space for aging parents or adult children
  • Offer a rental income opportunity
  • Serve as home offices, creative studios, or wellness suites

Because many MCM homes in Phoenix and Scottsdale include backyard space, rear alley access, or converted carports, there’s often room to build without disrupting the original home’s character.

What Makes a Guest House “Mid-Century Modern”?

A guest house addition doesn’t need to copy every feature of your main home—but it should complement it. Here are the key design elements we often incorporate:

  1. Low-Slung or Flat Rooflines
    Flat or low-pitch gable roofs reflect MCM sensibilities and pair well with post-and-beam styles.
  2. Material Continuity
    We often use concrete block, breezeblock screens, or horizontal siding that echoes the main structure.
  3. Large Glass Elements
    Sliding doors, clerestory windows, and corner glass details maintain light and transparency.
  4. Interior Simplicity
    Simple cabinetry, floating vanities, and modern fixtures with clean lines.
  5. Indoor-Outdoor Flow
    We align patios, shade structures, and landscape design to create a cohesive outdoor experience between the main home and guest house.

Featured Design Considerations for MCM Casitas

Maximizing Privacy Without Sacrificing Flow

We use walls, breezeblock screens, and landscape elements to maintain privacy between the main home and guest suite—while still designing for visual connection.

Matching Scale and Setbacks

Guest houses in MCM homes should never overpower the main structure. We design with proportion, scale, and spatial relationship in mind.

Integrating Outdoor Living

Covered patios, low-masonry walls, and mid-century-inspired landscaping ensure that both dwellings feel part of a cohesive whole.

Modern Performance Meets Vintage Charm

Our guest house interiors may include:

  • Floating vanities
  • Slab cabinetry in walnut or white oak
  • Polished concrete or terrazzo-style flooring
  • Energy-efficient glass and insulation
  • Smart home integration (lighting, HVAC, security)
