Meet Your Designer

After earning his interior design degree, Nick Konzal founded Nicholas Carl Design in 2008. In the upturn of The Great Recession, he booked a career-changing job redesigning a Henry DuPont Spanish Eclectic home in St. Petersburg, Florida.

Throughout six months of construction, he lived in the home and worked alongside the general contractor. He learned all the Ins and Outs of managing construction and executing a large-scale renovation. Now, his diverse skill set makes him a unique and incredibly knowledgeable interior designer. In 2022 he officially became a certified general contractor.

Nick’s design style is a perfect marriage of classic design elements and modern, cutting-edge choices. He strives to make each room flow like a work of art, the space becoming an experience in itself. His designs often feature clean lines, detailed moldings, rich colors, and fun textiles. He loves to incorporate family heirlooms as well as artwork by local and world-renowned artists and artisans.

Since its founding, Nicholas Carl Design has been awarded by and featured in publications across the United States. Nick has been a part of the Wisconsin Breast Cancer Showhouse for 10 years and currently sits on the design review board. Currently based in Milwaukee, his team transforms homes with luxury furnishing, interior design, and large-scale renovations in Southeastern Wisconsin, Chicago, St. Petersburg, and other West Florida communities.
