01 — What We Build
Six ways we'll
build for you.
From a new kitchen to a whole new home, we bring the same standard to every project: clean job sites, transparent communication, and the kind of craftsmanship that makes inspectors raise an eyebrow — in the good way.
Custom Homes
Architect-grade custom homes designed around how you live. Built with healthier materials and a build envelope made to last.
Renovations
Whole-home refreshes and structural renovations done with respect for what's already there — and what it should become.
Additions
Thoughtful additions that look like they were always part of the home — never bolted on. Engineered for the long haul.
Kitchens & Baths
The two rooms that move a home — done at a finish-carpentry standard, with low-tox finishes and zero corners cut.
ADUs (Accessory Dwelling Units)
Backyard cottages, in-law suites, and detached studios. Compact, durable, and beautifully built — drawing on our Z Panel DNA.
02 — Why Sativa
High quality, safe,
and superior.
Sativa Building Systems has spent years engineering safer wall assemblies — the patented Z Panel is proof. We're bringing that same standard of materials science and craft to every general contracting job we take.
Safe by Design
We build for the people who live inside. Non-toxic finishes, healthy air, and assemblies that resist mold, rot, fire, and pests.
Superior Craft
Trim lines that meet. Mitres that hold. Decades-long building science applied to every framed wall and finished surface.
Sustainable Materials
From locally sourced lumber to our patented Z Panel hempcrete, we choose materials that age well and tread lightly.
Transparent Process
Fixed schedules, clean job sites, and clear weekly updates. You'll always know what's happening on your build.
03 — How We Work
A calm, transparent
build process.
Most homeowner horror stories start with a fuzzy contract and a ghosted contractor. Ours starts with a real conversation — and ends with a finished home you're proud to show off.
- 01
Discovery & Scope
We sit down, walk the site, and listen. We get clear on the goals, the budget, the timeline, and the way you want to live in the space.
- 02
Design & Estimate
Drawings, materials, and a transparent line-item estimate. No vague allowances, no hidden margins — just a real plan you can sign off on.
- 03
Build
Our crews show up clean, on time, and accountable. You get weekly photo updates and a single point of contact from groundbreak to punchlist.
- 04
Walk-through & Warranty
A meticulous walk-through, a workmanship warranty, and a team that picks up the phone after the keys are handed over.
04 — About Sativa
The team behind
the Z Panel — now building your home.
Sativa Building Systems is best known for our patented hempcrete Z Panel — an engineered wall block that resists mold, fire, rot, and pests while passively filtering indoor air.
We're bringing that same obsession with safe materials and superior building science to homeowners across Central Wisconsin through our new residential general contracting service.
Whether you want a fully conventional build, a hybrid that incorporates Z Panel walls, or a fully non-toxic custom home — we can build it.
Founded On
