Casitas & Guest Houses

We design and build casitas and guest houses in Northern Arizona, with careful planning around your property, main home, and how the new space will be used.

A Casita Designed Around the People Who Will Use It

We plan the layout, privacy, access, rooms, storage, and utilities around how you want the space to work now and over time.

Guests and visiting family

A comfortable place to stay

We create a private, welcoming space that keeps guests close to the main home while giving everyone room to settle in.

  • Comfortable living, sleeping, and storage
  • Privacy with an easy connection to the main home
  • Access and outdoor areas that feel natural

Multi-generational living

Independent living close to family

We plan around daily routines, accessibility, privacy, and the right level of connection for a parent or adult child.

  • Room for everyday independence
  • Accessibility and ease of movement
  • Thoughtful parking, entry, and outdoor space

Long-term flexibility

Space that can adapt over time

We shape the rooms, storage, utilities, and exterior so the building remains useful as household needs change.

  • Flexible rooms and useful storage
  • Utility planning for the intended use
  • An exterior that belongs with the property

We Help You Understand What Your Property Can Support

We can help you determine what is possible, review the property and project requirements, answer your questions, and coordinate the planning needed to move forward.

The right plan is specific to the property. Zoning, setbacks, available building area, access, grading, drainage, parking, utilities, and the relationship to the main home can shape the location, size, and design.

What we review with you

  • Where the casita can sit and how it should connect to the main home
  • How people and construction crews can reach the site
  • How water, power, wastewater, parking, and drainage will be handled
  • Which privacy, view, accessibility, and outdoor-space priorities matter most

We also help coordinate the appropriate design, engineering, permitting, and local review. The applicable authorities and qualified professionals make final approval and technical determinations, and we keep the work organized so you have a clear path into construction.

How We Take a Casita From Planning Through Construction

We keep the project moving in a clear order, from early property review and design decisions through construction.

Understand how the space needs to work

We learn who will use it, how much privacy and independence they need, which rooms and utilities matter, and what budget range you want us to plan around.

Review the property and project requirements

We review the proposed location, access, grading, drainage, utilities, parking, and relationship to the main home so the design starts with the property in mind.

Coordinate design and approvals

We help coordinate the appropriate design, engineering, permitting, and local review so the project is ready for construction.

Build the approved project

We carry the approved direction into construction, coordinate the work, and keep important decisions and expectations clear as the build progresses.

Frequently Asked Questions

Does M4 design and build casitas and guest houses?

Yes. We design and build casitas and guest houses in Northern Arizona. We can help you think through the property, intended use, design, required reviews, and construction so you can move forward with a coordinated plan.

What is the difference between a casita and a guest house?

The terms often describe a separate living space for family or guests. The most useful distinction is how the building will function, which rooms and utilities it needs, and what local requirements apply. We plan from those practical needs rather than the label alone.

What affects the cost of a casita or guest house?

We develop a project-specific budget after reviewing the property and intended use. Size, site access, grading, utility work, room and fixture needs, exterior details, finish selections, engineering, and permitting can all affect cost, and final pricing follows the agreed scope.

How long does a casita or guest house project take?

We organize the work in a clear sequence and establish project-specific timing as the requirements and approved direction become clear. Design, engineering, local review, site preparation, material selections, and the final construction scope all shape the schedule.

Can the new building match my existing home?

Yes. We can coordinate rooflines, exterior materials, windows, doors, and architectural details so the casita feels connected to the main home. The exact approach is shaped by the existing architecture, site, and budget.

Can I contact M4 while the idea is still taking shape?

Yes. You can call us early in the process. We can review what you want the space to do, look at the property and project requirements, answer questions, and help coordinate the right planning path.
