Our focus is providing clients with a clear, upfront vision of expectations through a design/build approach. Our free design service provides potential customers with a collaborative consultation geared towards budget, wants, needs and lifestyle.

"Matrix was a pleasure to work with during our Finished Basement project. From the initial consultation through the completion, we were able to easily communicate and collaborate. Our Project Manager, Ben, was easy to get a hold of, quick to resolve any questions or concerns we had throughout the project. All subcontractors were professional, friendly and easy to work with. We are absolutely thrilled with the final project. Our basement is now the highlight of our home with space for the whole family and guests. We love the specialized features including hidden bookshelves and television/fireplace build out. Thank you for a wonderful experience and amazing finished basement."

My name is Joe and I started in the remodeling business when I was just 15. I have dedicated my life to learning the remodeling industry. We offer full remodels and specialize in kitchen, bathroom, and basement remodeling - give us your ideas and we make them into reality!

"Awesome, Joe was a true professional and did exactly what he said he would do installing our LVP. He explained that he would use floor leveling and what we should expect since our sub floor was so unlevel. It turned out great! We plan on calling him for future projects."

"Had a great experience with this crew. They built a paver patio in one day—super efficient, clean, and professional work. Price was the most competitive of out of 4 different companies I got quotes from. Communication was solid throughout, they stayed in touch regularly from quote to completion. They double-checked everything with me to make sure it was what I wanted. As a bonus, they removed some extra turf near the patio and filled in some bald spots in my lawn, which saved me a ton of effort. Quality of the work is great. Would absolutely recommend and hire again for future projects."

FAQs for guest house building service projects in Waukesha, WI

In most states, yes—you can build a guest house, but every city or county sets its own zoning rules and building codes. Before breaking ground, check local ordinances, confirm lot setbacks, and secure the right permits. A local contractor or design-build firm can walk you through the paperwork and site requirements so your project starts on solid legal footing.

Yes—homeowners often tap a few different financing tools. A home-equity line of credit (HELOC) lets you borrow against your equity as you need funds. If you prefer a lump sum tied directly to the project, a short-term construction loan can roll into a second mortgage once the build is complete. Cash-out refinancing is another option: you replace your current mortgage with a larger one and use the difference to cover construction costs.

When you build a guest house, you’re creating a separate structure for hosting visitors without the full amenities needed for permanent living. An accessory dwelling unit, however, includes a complete kitchen and bathroom, meeting building codes for a long-term residence. This key difference makes an ADU ideal for long-term occupancy or rental income, adding enduring value to your property.

How many rooms you need depends on how you plan to use the space. Aim for one bedroom per every one or two occupants to make sure everyone has enough privacy and comfort. Added living and dining areas give you extra functionality, especially for rental use or long-term stays.

Most homeowners pick somewhere between 600 and 1,500 square feet to fit all the essentials. Make sure your design supports one to two occupants per bedroom and includes enough common areas for comfortable daily living. A well-proportioned layout boosts both functionality and property value.

No—a guest house isn’t just a bump-out on your main home. A bump-out is a small extension within an existing room for extra seating or storage. In contrast, you build a guest house as a standalone building with its own foundation and amenities, giving you a fully separate living area that can boost your property’s versatility and value.
