What goes into our home additions & casitas work

Home Addition & Casita Options

Expanding your home opens the door to new possibilities: more space, more comfort, and more flexibility for the way you live. Whether you're building a private casita, adding a new bedroom suite, or converting unused space into something functional and modern, we offer carefully planned additions that feel seamless and fully integrated with your home.

  • Detached or attached casitas: Self-contained living spaces ideal for guests, multigenerational living, or rental opportunities. Designed to match your home's architecture with dedicated entries, bathrooms, and optional kitchenettes.
  • Next-gen and primary suite additions: Luxury expansions that create a true retreat, complete with oversized bedrooms, spa-style bathrooms, walk-in closets, and private sitting areas. Perfect for growing families or homeowners who want more comfort and privacy.
  • Garage conversions: Turn unused or outdated areas into valuable living space. Garages, lofts, and bonus rooms become offices, gyms, game rooms, theaters, or additional bedrooms, finished to look like they were always part of the home.

Why Invest in a Casita?

Casitas are one of the fastest-growing remodeling projects in Las Vegas. They provide flexible living space for:

  • Family members
  • Guests
  • Rental income opportunities
  • A private home office

In addition, they add value and versatility to your property while complementing your existing home.

Benefits of Building a Home Addition

A professionally designed home addition provides more than extra square footage. It can:

  • Improve functionality
  • Increase resale value
  • Give your family the space needed to grow without relocating

Whether you're adding a primary suite, expanding your living room, or building a detached casita, a custom addition is a long-term investment in your home.

FAQ

Common Questions About Home Additions & Casitas

Whether you're pricing a project or just exploring ideas, call (702) 560-2494 for honest guidance and clear answers.

Do I need a permit to build a home addition or casita in Las Vegas?

Yes, almost all additions require permits, including casitas, garage conversions, room extensions, and second-story additions. Las Vegas, Henderson, and Clark County each have their own permitting guidelines, and setbacks can vary by neighborhood. As licensed general contractors, we handle all permitting and inspections from start to finish.

How long does a home addition or casita typically take?

Timelines depend on size and complexity. Garage conversions: 6–12 weeks. Casitas and attached suites: 2–5 months. Large structural additions: 3–6+ months. We provide a clear schedule upfront so you always know what to expect.

How much does a home addition or casita cost in Las Vegas?

Pricing varies based on square footage, finishes, utilities (plumbing and electrical), and whether the space is attached or detached. Casitas with bathrooms and kitchens cost more than simple bedroom or office additions. During your consultation, we help you understand realistic cost ranges and options that match your goals.

Can I convert my existing garage into a livable space?

Absolutely. Garage conversions are one of the most popular upgrades in Las Vegas, especially for creating guest suites, game rooms, gyms, and home offices. Many neighborhoods allow it, as long as the space meets building code for insulation, egress, and HVAC. We ensure your conversion is safe, comfortable, and fully compliant.

Can you match the exterior of my existing home?

Yes, we blend rooflines, stucco textures, paint colors, windows, and design details so the new space looks like it has always been part of your home. Seamless integration is a key part of high-quality addition work.
