T-Squared Designs, LLC provides architectural and interior design services for projects of many scopes and sizes. Located in the Spring Green / Sauk City, Wisconsin area, we work with clients all over the Driftless region and South-Central Wisconsin- and beyond (sometimes clear across the country). We are a local, independently- and woman-owned business with formal and experiential training in both interior and architectural design, with a special fondness for remodel projects (especially full guts!)- though our projects run the gamut of new construction, additions, room remodels, exterior updates, and everything in between. We also provide kitchen and bath design services, and specialize in the design and specification of custom and semi-custom cabinetry for all types of spaces and styles. T-Squared Designs is currently working on a new studio and cabinet showroom space (more like design laboratory) located right between Spring Green and Sauk City but for now we operate on an appointment-only basis.

Interested in our services? Start with a phone call or email; we can chat about your project, and schedule a consultation. We look forward to hearing from you!


TARYN SEYMOUR, owner, principal designer, began her design career in Philadelphia over fifteen years ago. After earning an undergraduate degree in interior design, she joined the award-winning team at Performance Kitchens, where she cut her design teeth on all things kitchen and bath. Eventually deciding to return to school, she attended the Frank Lloyd Wright School of Architecture, where she earned a Master of Architecture degree, completed a Capstone, and graduated Cum Laude. After training with modern architecture great Michael Johnson and subsequently working with Taliesin Preservation Inc., she established T-Squared Designs, LLC in 2013 and works from her studio in beautiful Sauk City, Wisconsin.

Taryn is a mother, partner, and recent non-directed kidney donor.

T-Squared Designs is proud to specify CRYSTAL CABINETS as our first choice in cabinetry and architectural millwork. Located just next door in Princeton, Minnesota, Crystal can build anything we can design, with top-notch quality of boxwork, wood species, and finishes. And what we really love is that Crystal standardly uses no-added-urea-formaldehyde plywood for their boxwork (made in the USA!), offers rapidly renewable options for wood species, and even uses recycled materials for shipping. For more information, visit CrystalCabinets.com. Or better yet, give us a call and we can talk about your project.


T-Squared Designs, LLC is a member in good standing of the National Kitchen and Bath Association. Through this organization, Taryn (owner) has earned the designation of Cabinetry Specialist, which demonstrates proficiency and expertise in current kitchen and bath industry standards and nomenclature.
