Make Room for What Matters Most

At Trinity Homes AZ, we help you create new space without starting over, guiding you through every step with honesty, care, and a deep respect for your vision and investment.

Frequently Asked Questions About Home Additions

What are Some Popular Home Additions That Make Every Square Foot Count?expand_more

Your home should support the way you live. That’s why more families across Scottsdale and the East Valley are choosing custom home additions that give them room to breathe, gather, and grow. 

Common home addition projects include:

  • Owner’s suites with spa-inspired bathrooms and generous closets
  • Expanded kitchens with open layouts and plenty of storage
  • Additional bathrooms to ease the morning rush
  • Garage extensions for vehicles, hobbies, or extra storage
  • In-law suites or casitas that offer privacy for guests or extended family
  • Bonus rooms like home offices, playrooms, and more

Every addition is custom-designed and carefully built to feel like it’s always been part of your home.

What Are the Mistakes to Avoid With an Addition?expand_more

The biggest mistake is starting without a solid plan. A well-executed home addition should feel seamless and intentional, not like it's been tacked on.

At Trinity Homes AZ, we help you steer clear of common missteps like:

  • Rushing the design phase or not considering how the new space flows with your existing home
  • Underestimating the budget, especially for structural work or hidden site conditions
  • Choosing style over structure, resulting in poor long-term performance
  • Overlooking permits or zoning requirements that can delay your project
  • Not considering interior design that could affect the layout or size
  • Hiring separate teams instead of a full-service contractor who manages everything

We’ll walk with you through each step to ensure your addition is cohesive, code-compliant, and crafted to support your lifestyle.

How Much Does a Home Addition Cost in the Scottsdale, Arizona, Area?expand_more

Most home additions in Scottsdale range from $375 to $525+ per square foot, depending on your goals and the level of customization. The final cost depends on several factors, including the size and complexity of the project, the finishes you choose, and how much plumbing, HVAC, or electrical work is involved.

Some cost-driving choices might include:

  • Flooring: Luxury vinyl tile is more budget-friendly, while hardwood increases cost.
  • Counters: Quartz is durable and mid-range, while marble offers a high-end look at a higher price point.
  • Cabinetry: Stock options are affordable, but fully custom cabinets with built-ins raise the investment.
  • Bathrooms or kitchens: Additions with plumbing, gas lines, or venting systems will cost more than a simple living space, bedroom, or home office.

No matter your vision, we’ll walk through your priorities, help align design and budget, and provide a clear, itemized estimate so you always know where your investment is going.

Is It Better to Add on to My Home Or Move to a New One?expand_more

If you love your neighborhood but need more space, a home addition can be a smart, meaningful alternative to moving.

While a new house might seem like a fresh start, moving comes with hidden costs—both financial and emotional. With an addition, you get to keep what you love while gaining the exact space your family needs.

Here’s why many homeowners choose to add on instead of move:

  • Stay in the neighborhood you love without uprooting your routines
  • Avoid the costs of selling and buying, including realtor fees, closing costs, and moving expenses
  • Keep your home’s equity and invest it back into something that improves your daily life
  • Design exactly what you need, whether it’s an extra bedroom, expanded kitchen, or multi-purpose suite
  • Skip the market stress — no bidding wars, no packing boxes, no starting over

If you’re not ready to leave your home but need it to work better for you, we’re here to help you explore the possibilities.

Why Home Additions are the Contemporary Solution

As your life changes, your home should be able to keep up. When things start to feel a little too snug, but you love where you live, a home addition can be the perfect way to grow without going anywhere.

  • Room to Breathe
    Life happens — families grow, hobbies expand, and routines shift. Adding on gives you the extra space you need, from an expanded kitchen to an extra bedroom, without the stress of moving.

  • Long-Term Value
    More square footage means more value. Whether it’s a sunroom, a new bathroom, or an in-law suite, additions can significantly increase your home’s resale potential down the road.

  • Smart Investment
    Buying a bigger home comes with a hefty price tag. An addition gives you the space you need without the cost and chaos of relocating, making it a practical way to invest in your future.

  • Built for You
    Your home should reflect who you are today. A home addition lets you design with intention — think cozy window seat, bright home office, or a new wing for multigenerational living.

With the right plan and team behind you, adding on is less about square footage and more about making home feel just right again.

Our Design-Build Process

1 | Listen & Plan

We begin by learning about your vision, lifestyle, and goals for your home. Then we connect you with architects, engineers, and our in-house interior designer to shape the plan. Every detail is considered early on so we can build with confidence and clarity.

2 | Estimate & Prepare

While the design comes together, we gather trade bids and create a transparent, line-item estimate. You’ll know exactly where your investment is going, with no surprises. Once approved, we schedule work, order materials, and prep your site for a smooth start.

3 | Build & Support

From demo to final walkthrough, we manage every phase with precision and care. You’ll receive weekly updates, site walks, and open communication throughout construction. And even after move-in, we’re here with dedicated support and a clear warranty plan.

Custom Home

Trinity Homes Phoenix kitchen renovation with marble island and custom hood range

What Our Clients Think

"I have worked with Trinity on multiple projects and highly recommend! I grew up in a construction family. My grandfather developed properties, my father designed and built high-end homes, and my 2 brothers are still in the construction business. Needless to say, I have extremely high standards when it comes to detail and the construction process. I also own a development and design company, and my first call is always to Slade and the Trinity team! They come in with strong estimates, and I appreciate their communication. They use a project management tool/site that is very user-friendly and everything is all in one place. They also update with pictures of the project often. Trinity is honest, full of integrity, and incredible at their craft! 5 stars all the way!"

What Our Clients Think

"Best renovation experience we've had yet! From start to finish, Trinity has been a great partner and I highly recommend them. When looking for a contractor, we got 3 bids for our whole house renovation. Trinity came in the middle of the bids price-wise, but we liked their systems (a building app where we could track daily job progress) and they do a lot of due diligence in pre-construction so there would be no surprises along the way. This work absolutely paid off and the job went smoothly, on budget, on schedule and we all still like each other! We would use them again without hesitation."

Remodel + Addition

Contemporary kitchen with large marble island and floor-to-ceiling windows by Trinity Homes in Paradise Valley

What Our Clients Think

"We worked with Trinity Homes AZ in 2023 & 2024 to renovate our Paradise Valley home. We took the house down to the studs and the end result was beautiful. We are so pleased with our new home! Trinity project management and communication are strong and workmanship has been excellent. Given that it was a renovation of an older home, the project was not without issues. However, Trinity worked diligently to resolve every issue that came up. Slade and his team are honest and fare and care deeply about each project Trinity takes on. We are very grateful. Thank you, Trinity team!"
