Where Design Meets

the Jobsite

A Design Firm That See’s

Things Your Way



At Wren House Design, we partner with builders to bring elevated, cohesive design to custom homes and spec builds. Whether it’s selecting exterior materials, refining floor plans, or crafting a seamless interior story, our goal is simple: to make your product stand out and your process smoother.

Alyssa’s time working within an architecture firm shaped the way she approaches design today. Alyssa was deeply involved in the development of construction sets, updating drawings, refining details, and collaborating closely on things like electrical layout and plan coordination. That experience gave her a strong understanding of how homes are built on paper and on-site. She knows how to read a set, communicate with your team clearly, and make design decisions that support both the vision and the build. It’s this hands-on knowledge that helps us create designs that are not only beautiful but buildable.

Your Build Blueprint

We know how important it is to get the details right before anything’s built. That’s why we make it a priority to be on-site during key phases walking through our design with you and your trades, answering questions, and reviewing placements in real time. From cabinet elevations to lighting locations, these walkthroughs ensure the design intent is clearly communicated and aligned with the construction plan. Our goal is to keep things moving smoothly, avoid confusion, and make sure everyone is working from the same page before materials are ordered or walls go up.

Aligning on the Details

We truly value the relationships we build with our trusted builder partners. Growing these connections ensures that every project we collaborate on is a success because when we work closely together, we make the right decisions at the right time. It’s this teamwork and shared commitment that bring our designs to life seamlessly. We’re excited to continue nurturing these partnerships and tackling more incredible projects side by side.
