National Construction, NCI-Roberts Construction and Supreme Structures — all three commercial divisions of JG Development — are uniting under one name.

We're making this change to better serve our clients and partners. We want it to be easy for you to work with us and refer us to others!

You'll notice gradual changes; we hope to be fully transitioned in early 2026.

Rest assured we are the same team — committed to trust, transparency, and supporting greater Madison's growth.

Thank you for your trust and support as we move into this next phase!

National Construction renovated a more than 150-year-old former church in Sun Prairie into a larger and more luxurious location for Faded Roots Boutique.
