Add the space your Scottsdale home needs without the chaos of a typical construction project
Fenn Rogers Custom Homes delivers large-scale home additions in Scottsdale that blend seamlessly with your existing architecture. From owner suites and guest casitas to great room expansions and second stories, our team coordinates design, permits, and construction with the same care we bring to building custom homes from the ground up.
More space, better flow, and a home that feels cohesive—not pieced together
Additions that look original
Rooflines, elevations, window styles, and details are carefully matched so your addition feels like part of the original home instead of an obvious “bolt on.”
Structural and exterior detailing considered from the first concept.
Clear budget and timeline
We establish realistic budgets and schedules before construction begins. You see how choices affect cost and time, so there are no surprises halfway through the project.
Allowances and options documented in writing.
Respect for your everyday life
We plan access, dust control, and phasing to protect the parts of your home you already love and minimize disruption while work is underway.
Weekly updates keep you informed and in control.
Trusted by Scottsdale families reimagining homes they already love
Complex additions handled with confidence. From second stories to major structural changes, our team understands engineering, utilities, and permitting in Scottsdale.
Consistent communication. You receive regular updates with photos, milestones, and upcoming decisions so you always know what is happening next.
Enduring quality. We use materials and assemblies that perform in the desert climate, so your new spaces feel solid and comfortable for years to come.
Local permit expertise. Our team navigates Scottsdale's zoning and setback requirements, city regulations, and HOA guidelines so your project moves forward without unnecessary delays.
Long-term relationships. Many of our addition clients return to us for future projects or refer friends and family.
A clear three-step plan for your Scottsdale home addition
Assessment and concept
We walk your home, listen to how you want to live, and study the structure, utilities, HOA guidelines, and site. Together we define the best way to add space and improve flow without overbuilding.
Design, budget, and approvals
We collaborate with your architect and designer or bring in trusted partners. During this phase we align drawings, selections, budget, and Scottsdale permits so the project is truly ready to build.
Build and protect
We build the addition while protecting the parts of your home you already love. You receive weekly updates and a clear plan for each stage until the new and existing spaces come together as one cohesive home.
A zero-surprise approach to large home additions
Transparent proposals
Scope, allowances, and exclusions are clearly defined so you understand exactly what is included before work begins.
Hands-on oversight
You have direct access to ownership and a dedicated project lead who knows your home, your plans, and your priorities.
Craftsmanship that lasts
Our trade partners are chosen for skill and reliability. Details are finished with care so your addition feels as solid as a new custom home.

There are so many cool features at our Skyview 5 project, like the floating steel staircase to access the bedrooms upstairs right off the kitchen. Stay tuned as we are nearing completion on this amazing custom home 🙌🏻
We’ve wrapped up the framing portion of phase 2 at our Mariposa Estates project. Phase 2 consists of building a game room to connect the main house to the casita with a game room as well as adding 3 additional garage bays 👊🏻
Most people would look at this project and say you should’ve just scraped the house and started from scratch! But this home has sentimental value to our clients so we are preserving as much as we can 🙌🏻

Frequently asked questions about home additions in Scottsdale
Most large additions we complete in Scottsdale fall in the range of several months to more than a year from permit ready plans to completion. Timing depends on the size of the addition, structural changes, level of finish, and the approval process. During preconstruction we map a realistic schedule so you know what to expect at each stage.
Many clients stay in the home for at least part of the project. In those situations we pay close attention to safety, access, dust control, and noise. We will review the scope and layout with you and give clear guidance on whether staying in the home makes sense and what that experience will be like week by week.
That is our goal. We pay attention to roof pitch, eave depth, window style, door heights, floor transitions, and trim details so the addition feels integrated with the original structure. We can either match the existing style closely or update both new and existing areas so the whole home feels fresh and cohesive.
Yes. We coordinate with your architect and engineer or bring in trusted partners to create permit ready drawings. We are familiar with Scottsdale requirements and work to anticipate approvals, inspections, and any association reviews that may be needed for your property.
During your consultation we look at your lot, current layout, and long term plans. In some cases a well planned addition is the best answer. In other situations a new custom home or a whole home rebuild may be a better fit. We walk through the pros, cons, and investment of each path so you can decide with confidence.
