About Black Walnut Studio
Every remarkable piece of furniture begins long before the first cut.
For John Romadka, every tree carries a story worth preserving.
THE STORY
Every Tree Deserves
a Second Life
John Romadka doesn't simply build furniture.
He creates functional art.
Every drought, every storm and every season is recorded inside the grain of a tree. Rather than hiding those marks, John celebrates them.
Twenty years ago he began teaching himself woodworking while building furniture for his growing family. What started with a cherry blanket chest became dining tables, beds, entertainment centers and countless heirloom pieces.
For nearly twenty years he built for exactly one client—his own family.
When his corporate career unexpectedly came to an end, everything changed.
He already had the workshop. The tools. Twenty years of experience.
The business had quietly been preparing itself all along.
Today Black Walnut Studio creates custom furniture built around one simple philosophy:
Every tree deserves a second life.
AT A GLANCE
THE PROCESS
FEATURED
The Burnt Ember Desk
Most craftsmen would have cut away the fire damage.
John built around it.
The Bastogne walnut slab had survived a fire, leaving a charred scar running through its center. Instead of hiding the damage, he stabilized it using ebony bow-tie keys and preserved its history with deep black resin.
The result became one-of-one functional art.
A piece that could never be recreated.

SOURCING
Materials Matter
John is drawn to Bastogne Walnut because of its incredible depth, movement and rarity.
Every slab contains dramatic figure and shifting color that simply can't be replicated.
Rather than covering the wood beneath heavy finishes, he uses premium European hardwax oils that protect while allowing you to still feel the grain beneath your fingertips.
Production furniture runs on compromise.
I don't.
If a step makes the piece better, even if nobody will ever see it—I still do it.
Craftsmanship is measured by the details hidden inside every piece; the joints you'll never see, the reinforcements buried beneath the surface, the extra hours spent making something right rather than simply making it done.
Building custom furniture means never apologizing for taking the time to make something exceptional.
Start small.
Build often.
Let every project teach you something.
Craftsmanship is earned one project at a time.
THE WORK
Explore My Collections


This C-table is cut from a single piece of Pacific Northwest big leaf maple burl — split in two, with its only sibling, Timberline, listed alongside it. Burl is the tree's stress response: dormant buds erupting all at once, grain running in every direction instead of with the trunk. The voids that come with that kind of growth are filled in black resin, poured full-field across the surface, so the figure stays the only thing you're looking at.
Finished by hand in European hardwax oil, which soaks into the wood rather than sitting on top of it — a scratch years from now is a spot repair, not a refinish. Built on a powder-coated steel C-frame, matte black, that slides alongside a sofa or chair, its slim profile giving the burl room to do the visual work. Functional art in big leaf maple burl, and one of one.

CONSTRUCTION & CRAFT
Built by Black Walnut Studio, LLC in Madison, Wisconsin. The burl slab was flattened and the voids poured full-field in black resin before final shaping. Finished with a hand-applied natural-oil hardwax that bonds with the wood fibers rather than sitting on top of them. The base is a powder-coated steel C-frame, matte black, profiled to disappear under the visual weight of the top.
CARE INSTRUCTIONS
Wipe with a damp cloth; avoid harsh cleaners and abrasive pads. For spot repair or annual refresh, apply a fresh coat of European hardwax oil with a clean cloth — no sanding required. Keep room humidity reasonably stable (35–55%) to let the wood do what wood does.
