How It Works
Most homeowners hire a contractor first and make design decisions during construction. We reverse that process.
-
You’re excited about your project but aren’t sure where to start or what decisions need to be made first.
-
We help you think through the layout, design, materials, and overall vision before construction begins, so you can move forward with clarity.
-
Take your completed plan to your contractor knowing the important decisions have already been made, reducing surprises during construction.
“So happy to have met with Stefany, she was beyond helpful. I went in with one project/idea in mind and she helped me envision other options. We have started our project and look forward to continue to working together to finish this project and start another. Highly recommend this service!”
When you work with House by Ortega, you are not just hiring a design consultant. You are getting structured guidance through one of the most important phases of your home project — the decisions that happen before construction begins.
This is not surface-level design. It is planning that helps you avoid costly mistakes and move forward with clarity.
From Planning → Action
Real projects guided through pre-construction planning and design direction.
“I recently worked with House by Ortega on an ADU conversion, and I couldn’t be happier with the experience. They were invaluable to me, especially given my lack of knowledge in construction in general and limited time and patience. Not only did I feel very connected to the project without having to invest a lot of my own time, but their expertise gave me peace of mind throughout the process.
From the start, they demonstrated genuine passion for their work and offered valuable advice. A great example was the initial layout of the unit, even though I had hired an architect for this phase, they provided insightful recommendations and adjustments even before I fully engaged them, which immediately made me comfortable with their expertise.
I trusted Stefany completely with the color choices, bathroom design, living space, and all the finishing touches. She balanced tasteful design with affordability, which was important since this ADU will be a rental. Overall, they made a complex and important project feel manageable and enjoyable, and I highly recommend their services.”
