Most kitchens get updated. This one got a conversation. 🍳🔨

The homeowners had a vaulted knotty pine ceiling that gave the space real character. Instead of covering it up, we built around it. Crisp white Shaker cabinets that run all the way to the ceiling. Marble-look countertops and backsplash. A professional gas range with red k***s that pops against the whole neutral palette.

Floor-to-ceiling pantry for serious storage. Built-in wall unit for cookbooks and serving pieces. Light wood flooring that ties the pine ceiling and white cabinets together without fighting either one.

Updated everything that needed it. Kept everything that made it special. That's what a good kitchen remodel actually looks like. 💪

Thank you to the team who helped bring this one together:

PLUMBING: Ahern-Gross Plumbing
ELECTRICAL: Kollmann Electric LLC
HVAC: Air Tech Heating, Inc.
DRYWALL: Solid Rock Drywall & Plastering LLC
PAINTING: Gene Zenner

Built from scratch in Campbellsport, and worth every detail. 🏡🔨

This modern farmhouse started with a family who had a clear vision and a rural lot that gave us room to do it right. We spent the week walking you through how it came together, but here's the full picture.

White siding with natural stone accents and a roofline that adds character without complicating the build. A covered front porch with wood-planked ceiling and composite decking built to handle Wisconsin winters and summers both. Step inside and the kitchen tells the same story. Custom white cabinetry, a center island with built-in cooktop, and a stone backsplash that anchors the whole space.

This is what new home construction looks like when the homeowners know what they want and the builder doesn't cut corners getting them there. Every structural decision, every finish choice, every detail on this build was intentional.

If you know a friend or family member dreaming about building their own place, tag them or share this with them. 📤

We build in the Fond du Lac and Oshkosh areas and beyond. If you've got a lot and a vision, we'd love to talk. Link in the comments.

Modern farmhouse charm meets Wisconsin-built quality. ✅

White siding and stone on the outside. Custom kitchen, covered porch, and craftsmanship throughout on the inside. This is what new home construction looks like when the homeowners know what they want and the builder knows how to deliver it.

The kitchen is where this one really delivers. 🍳

Custom white cabinetry. Center island with a built-in cooktop. Stone backsplash that ties everything together without trying too hard. This kitchen was designed for real life, not just for photos.

Step onto that front porch and the wood-planked ceiling and composite decking tell you everything you need to know about how this whole build was approached. Nothing was an afterthought.

Kitchen island: yes or no? 👇

Couldn’t let the day pass without wishing a VERY HAPPY BIRTHDAY to Steve!

If you see him today make sure to give him a hard time! 🤪

Without him, none of us here at Steve Wirtz Builders would be here!

Custom from the ground up. 🔨

Every detail on this build was thought through before the first nail went in. Structural decisions that support the dramatic roofline. Framing that sets up the interior exactly the way the family envisioned it. A covered front porch built with composite decking and a wood-planked ceiling so it actually holds up to Wisconsin weather year after year.

New construction isn't just building a house. It's building the right house for the right family on the right lot.

What's the one detail you'd never compromise on in a build? 👇

Modern farmhouse in Campbellsport. This one had a clear vision from day one. 🏡

White siding, natural stone accents, and a roofline that gives the home real character without overcomplicating it. Rural setting, room to breathe, and a family ready to build something that actually fits how they live.

That's the kind of project we show up for.

Modern farmhouse, craftsman, ranch, what's your dream style? 👇
