Lonnie Nelson grew up in construction — literally. The son of a carpenter, he spent his childhood on job sites, and over 34 years has worked through every phase of building a home, from digging footings and framing walls to finish carpentry and project management. That hands-on depth shapes every decision at LJ Nelson Construction.

Today, Lonnie and project manager Melissa Christou lead a firm that does things differently. They integrate building biology principles into every project — prioritizing non-toxic materials, healthy indoor air, and moisture-conscious assemblies that go well beyond code. Whether it's a full-scale remodel, a custom new build, or an ADU, they treat every home as something that should actively support the health of the people living in it.

Based in Santa Barbara, the company specializes in the kind of projects that require real experience: complex remodels, ground-up construction, and additions where the details matter as much as the big picture.
