LINEA began with Steven at a drawing board—first as a residential designer and architectural intern, then as an architect determined to understand not only how buildings are designed, but how they are actually built.

The line that connects us
The
Story
From a drawing board
to one connected team.
LINE + A—for architecture—makes us LINEA.
Our people make us Team LINEA.
And we invite you to think
.
-
The beginning
At the drawing board
Residential design and architectural practice sparked a question: how can a building be designed better by understanding how it is built?
More of the story: At the drawing board
-
A shared language
Seeing every side
Experience with developers, contractors, and owners shaped a more direct way to communicate, explain decisions, and move a project forward.
More of the story: Seeing every side
Long before LINEA had a name, Steven Johnson was experiencing—and occasionally wrestling with—the inefficiencies of the traditional design and construction process. He continually looked for ways to simplify the work, improve communication, and make the journey from idea to completed building more efficient. More importantly, he discovered that he genuinely enjoyed explaining the process to clients and helping them make informed decisions.
Having worked for developers, contractors, and owners, Steven understands how each approaches a project, communicates priorities, and defines success. They may all be discussing the same building, but they are not always speaking the same language. His experience across those perspectives gives LINEA the tools to translate, navigate difficult conversations, and keep the entire team moving in the same direction.
-
Broader expertise
Design meets construction
Commercial architecture, interior design, and a general contractor’s license brought design intent and practical construction knowledge together.
More of the story: Design meets construction
As the company evolved, Steven expanded its work into commercial architecture and interior design. He also earned his general contractor’s license to ensure LINEA would always have the practical knowledge and resources to address construction, craftsmanship, and quality—because a beautiful detail is only successful if someone can build it.
-
Beyond the surface
Looking closer
Construction experience and an interest in historic preservation and adaptive reuse led into building forensics and litigation support.
More of the story: Looking closer
That construction experience, combined with Steven’s interest in historic preservation and adaptive reuse, naturally led LINEA into building forensics and litigation support. Buildings, after all, have a way of revealing their history—sometimes quietly, and sometimes through a roof leak.
-
Complementary people
A team takes shape
Elizabeth, Toby, Suzanne and Jeff joined Steven’s vision with complementary experience. The company became Team LINEA.
More of the story: A team takes shape
Along the way, Steven met Elizabeth, Toby, Suzanne and Jeff, partners who shared his vision, complemented his experience, and believed in a more comprehensive approach to the built environment. The company became a team—and Team LINEA was born.
-
Still building knowledge
One continuous line
A direct path from idea to completion—and onward into lasting relationships with owners and occupants.
More of the story: One continuous line
The name reflects that philosophy. A line is the most direct path from Point A to Point B, from beginning to end. Yet in our approach to Building Knowledge, that line never truly ends. It establishes the baseline and horizon for every project decision, extending through design and construction—and beyond completion into lasting relationships with owners and occupants.

The practice behind the name
The names along the line
Earlier studios. Today’s architecture, construction, and development businesses.
More of the story: The names along the line
Team LINEA’s history includes Steven Johnson’s work through Brown Dog Designs, Southern Evergreen, A408 Studio, and Steven Johnson Architect PLLC (SJA). After SJA, LINEA Corporation operated under the DBA LINEA Design Studio as a residential design studio, not a licensed architecture firm. That corporation evolved into LINEA Construction and continues today as the company’s construction wing, holding the construction license. LINEA Architecture and Interiors PLLC is the company’s current architecture and interiors legal entity. LINEA Sage is its development and investment division.
