Home Additions
Room additions and second-story builds that feel original to your home
From a single-room addition to a full second story, we design and build additions that blend seamlessly with your home's existing architecture — handled by one design-build team across Arizona.
What’s included
From first sketch to final inspection
A home addition involves more structural and permitting complexity than almost any other renovation. We manage the architecture, engineering, and construction under one design-build process, so nothing gets lost between the drawings and the framing crew.
Architecture that blends in
Rooflines, window proportions, exterior materials, and interior transitions designed to match your home's existing architecture, so the addition reads as original rather than obviously added on.
Structural & permitting coordination
Structural engineering, foundation work, and the full municipal permitting process — a core hurdle on any addition — managed from application through final inspection by one team.
Room additions
A new bedroom, home office, expanded living area, or in-law space designed and built as a natural extension of your existing floor plan.
Second-story builds
Adding a full second story where lot size or setback limits rule out building out — a bigger structural undertaking, planned around your existing foundation and roof structure from the start.
Sunrooms
Light-filled, climate-considered sunroom additions that extend living space toward the backyard, detailed for Arizona's sun exposure and temperature swings.
Interior flow & finish matching
Flooring, trim, and finish transitions between old and new space planned at the design stage, so the addition feels like part of the house rather than a visibly separate wing.
Who it’s for
For homes that have outgrown their footprint
A home addition is right for homeowners who love where they live but need the house itself to do more.
- Growing families who need more bedrooms or living space without leaving a neighborhood or school district they're attached to.
- Homeowners who need a dedicated home office or flexible workspace separate from the rest of the house.
- Multi-generational households planning a private suite or in-law space for aging parents or adult children.
- Anyone who's outgrown their current floor plan but loves their lot, location, or home's bones too much to move.

The decision framework
Build up, build out, or move?
Before we talk floor plans, we help you answer a more fundamental question: is an addition even the right move for your home and budget? We walk every homeowner through this framework at the start of the conversation.
Build out
Usually the simpler, less expensive path when your lot has the space and setback allowance for a ground-floor addition. The right first option to evaluate for most homeowners.
Build up
A second-story addition preserves yard space and works on smaller lots, but it's a bigger structural project — your existing foundation and roof structure need to be evaluated early.
Move
Sometimes the right answer — but factoring in selling costs, buying costs, and the disruption of moving, an addition is often the more economical and less disruptive path for homeowners who already love their location.

Home addition FAQ
How much does a home addition cost in Arizona?
Home addition costs vary significantly based on square footage, whether it's a single-story addition or a second-story build, and finish level. As a general reference point, most additions we design fall in the [$X–$Y] range. We'll give you a realistic number specific to your project during a consultation.
Is it cheaper to add an addition or move to a bigger house?
It depends on your local real-estate market, how much you love your current lot and location, and the scope of the addition itself. In many cases, an addition costs less than the combined expense of selling, buying, and moving — and lets you keep the yard, neighborhood, and layout you already know. We walk every homeowner through this build-up vs. build-out vs. move decision as part of the initial consultation.
Should I build up (second story) or build out (ground-floor addition)?
Building out is usually simpler and less expensive when you have the lot space and setback allowance for it. Building up makes sense on smaller lots or when you want to preserve yard space, but it's a bigger structural project since it typically requires reinforcing the existing foundation and roof. The right answer depends on your lot, your home's existing structure, and your budget — something we evaluate together early in the design process.
How long does a home addition take from design to completion?
Timelines vary widely depending on scope, but most single-room additions run several months from initial design through final inspection once permitting is factored in, with second-story additions taking longer due to the structural work involved. We'll map out a specific timeline once your design and permitting scope are finalized.
Will my addition actually match the rest of my house?
That's the core of what design-build architecture work is for — matching rooflines, siding, window styles, and interior finishes so the addition reads as part of the original home, not an obvious add-on. It's one of the first things we evaluate when we walk your property.
