Carbon World Health was the country’s first medically supervised spa and fitness facility, owned by a doctor, an esthetician, and a personal trainer. The interior renovation and buildout in Madison brought that unique combination to life in a space that deliberately feels like two different worlds. One side reads as a raw, energetic fitness gym; the other carries the calm, polished feel of a spa. Bold colors and brand-specific contemporary furnishings tie the two together without softening either one.

The facility includes a personal training gym, locker rooms with showers, a lounge, reception, cryotherapy area, physician and esthetician rooms, and spa treatment rooms. The design served a clear vision: a place where fitness, health, and beauty exist under one roof, backed by medical expertise.

Peter Kraus came to this project with a clear vision – a personal training studio that felt contemporary and industrial without losing warmth. The 3,150-square-foot buildout in Middleton brings that vision to life through a mix of rustic woods, clean white subway tile, stained concrete, and fitness flooring. A custom mural wall gives the space a distinctive focal point that doubles as a natural photo moment for clients. The layout covers a reception and retail area, personal training studios, open fitness areas, lockers, restrooms, and support spaces: everything a focused fitness business needs, arranged to feel intentional rather than improvised.
