Why Lighting Is a Design Discipline — Not a Design Phase
I want to challenge something that I see consistently in the work of designers at every level of the industry — including designers whose spatial thinking and material sensibility I genuinely respect.
The tendency to treat lighting as a late-stage decision.
I understand why it happens. The concept phase is where the big ideas live — the geometry, the parti, the relationship between water and landscape and structure. Lighting feels like an implementation detail by comparison. Something to be resolved once the design is established.
But here's what that sequencing costs you. And it costs you more than most designers realize.

Kirk Bianchi and Janet Lennox Moyer — author of The Landscape Lighting Book, the industry's definitive reference on architectural landscape lighting — walk through a completed Bianchi Design project, examining the principles and decisions behind the lighting composition.
On Learning From the Best
Before I get into the substance of what Janet and I discuss in this video, I want to say something about the value of seeking out the very best practitioners in disciplines adjacent to your own — and learning from them directly.
Janet Lennox Moyer is the author of The Landscape Lighting Book — the definitive reference on architectural landscape lighting, and a text I return to regularly even now. She is, without question, one of the world's leading authorities on the subject. I've had the privilege of learning lighting technique from her directly, and that education has shaped my practice in ways that continue to compound over time.
There is no substitute for learning from someone who has spent a lifetime mastering a discipline you're still developing. The Bianchi Method™ is built on a commitment to that kind of deliberate, humble, sustained learning — seeking out the best, studying what they know, and integrating it into your own practice with rigor and patience.
This video is a product of that commitment. And I hope it models something worth emulating.
What Gets Lost When Lighting Comes Last
Let me be specific about what the late-stage lighting approach actually costs.
When lighting enters the design process after the spatial decisions are made, it's working with whatever it's given. The materials have been selected without consideration for their nocturnal qualities. The architectural elements have been positioned without thought for how they'll read after dark. The planting plan has been developed without reference to the silhouettes and shadows it will cast under artificial light.
The result is a space that may be beautifully lit — technically competent, professionally executed — but that doesn't feel designed for the night. Because it wasn't.
Contrast that with what becomes possible when lighting is in the room from the very first sketch. Materials chosen partly for how they absorb and reflect light at different hours. Curved walls positioned to become light capture devices as the sun moves. Plantings selected with their nocturnal silhouettes as part of the brief.
“When lighting enters the design process at the concept stage, it doesn’t just illuminate the finished space. It shapes the space itself — every material decision, every architectural gesture, every planting choice.”
This is the distinction Janet and I explore in this video. And it's one of the most significant shifts a designer can make in how they practice.
The "Painting With Light" Framework
The metaphor Janet and I return to throughout this conversation is painting with light — and I want to unpack it briefly, because it's more than a poetic description.
A painter doesn't illuminate a canvas evenly. They use light and shadow with intention — to create depth, to guide the eye, to establish mood, to reveal form selectively. The best architectural lighting designers work exactly the same way. They're not asking "how do I make sure everything is visible?" They're asking "what do I reveal, what do I suggest, and what do I deliberately leave in shadow?"
That's a compositional question. And it belongs in the same conversation as your parti — not in a separate meeting with a lighting contractor six months later.
In the video, Janet and I use on-screen markups on a completed project to show the difference between lighting decisions that reinforce the composition and those that would undermine it. It's one of the clearest demonstrations I know of how to apply this thinking to real work.
A Practical Starting Point
If you take one thing from this video, let it be this: add lighting to your Phase I conversation.
Not the fixture schedule. Not the lumen calculations. But the spatial and compositional questions — how will this space feel after dark? What should be revealed? What should recede? How does the nocturnal experience of this space serve the overall design intent?
Those questions will change the decisions you make in every other discipline. And the spaces you produce will be measurably richer for it.
