Bringing Your Home Vision to Life Before the First Nail is Hammered
Siblings Bobbi Brandt and Chad Stoughtenger are the partners behind Castle Rock Design and Build, a company born from decades of combined experience and a shared vision to improve the way people build homes.
Bobbi has been in the real estate industry since 1998, while Chad has been working in the building trades since 2003. Over the years, they kept seeing their two professional worlds collide: buyers needing homes, and builders needing better ways to communicate what those homes would truly look and feel like. So they decided to do something about it.
Bobbi recognized the growing housing shortage and the overwhelming demand for new, quality homes, especially in South Central Wisconsin. At the same time, Chad saw firsthand how stressful it was for clients to make major design decisions without being able to fully visualize the outcome. Together, they found a solution. Launch a building company that combines smart construction with visual clarity.
They partnered with an architect and a 3D rendering specialist to create a design process that lets clients walk through their future home before construction even begins.
When clients meet with Castle Rock Design and Build, they aren’t just looking at blueprints. They’re exploring fully rendered 3D models that show every detail of the home. From flooring and siding to lighting and furniture placement, it’s all there to see and adjust in real time. Want to know if your heirloom hutch will fit in the dining room? The team can drop it into the model to scale. Curious how the flow from the kitchen to the patio will feel during family gatherings? You’ll experience it before a shovel hits the dirt.
This level of clarity eliminates the common emotional rollercoaster that comes with traditional building. Clients don’t have to guess what a space will feel like once the drywall is up or the windows are in. They’ve already seen the end result and made confident choices along the way.
Castle Rock Design and Build has pre-priced and pre-bid one of their home plans with real-world numbers, removing much of the financial uncertainty that often comes with custom construction. The result is a building experience that is transparent, empowering, and enjoyable.
By combining decades of experience, cutting-edge visualization tools, and deep local roots, Bobbi and Chad have created more than just a building company. They have created a better way to bring your dream home to life.
Chad Stoughtenger | General Contractor
Chad Stoughtenger has been building custom homes in South Central Wisconsin for over 22 years. His journey into the trades began back in high school when a wood tech program sparked a lifelong passion for carpentry and craftsmanship. Inspired by hands-on time with his grandfather in the garage, Chad quickly discovered that building homes wasn’t just a skill—it was his calling.
As co-founder and lead builder at Castle Rock Design and Build, Chad brings a client-focused approach to new construction. He takes pride in working closely with each homeowner to design and build a space that reflects their vision, lifestyle, and needs. Every home is a true one-of-a-kind, shaped by collaboration and careful planning from the ground up.
What sets Chad apart is his commitment to building one project at a time. This focused approach allows him to be on-site daily, overseeing every phase of construction to ensure precision, quality, and accountability. From the initial concept and floor plan design to the final walk-through, Chad is fully engaged in the process, ensuring no detail is overlooked.
In addition to his work in homebuilding, Chad is an avid outdoorsman who enjoys fishing, hunting, and exploring the trails. He is deeply rooted in the community and values the lasting relationships he builds with clients just as much as the homes he creates.
