Glass, Steel & Timber: Our Material Philosophy
A deep dive into the material palette that defines every Lookout Tower — and why we chose each element for its relationship to light and landscape.
Every material in a Lookout Tower is chosen for its relationship to light, weather, and time. We work with three primary materials — structural steel for resilience, engineered timber for warmth, and high-performance glass for transparency. Each plays a distinct role in the sensory experience of the tower.
Steel: The Skeleton
Steel provides the skeleton that allows us to cantilever over cliff edges and span across ravines. We use weathering steel (Corten) exclusively — a self-healing alloy that develops a protective rust patina, eliminating the need for paint or surface treatment. Over decades, the steel darkens and mellows, becoming more integrated with its surroundings rather than less.
Each structural connection is CNC-milled to sub-millimeter tolerances, allowing dry assembly on site without welding. This precision reduces construction time by weeks and eliminates the noise, fire risk, and visual disruption of on-site fabrication.
Timber: The Soul
Timber grounds the interior with organic texture and acoustic softness. We source engineered cross-laminated timber (CLT) from sustainably managed forests in the Pacific Northwest. CLT panels are prefabricated to exact dimensions, arriving on site ready to install.
The warmth of timber is more than aesthetic — it's acoustic. Wood surfaces absorb and diffuse sound in a way that hard materials cannot, creating interiors that feel quiet and enveloping even when the wind is howling outside. We leave all timber surfaces unfinished, allowing them to develop a natural patina that records the building's history.
Glass: The Canvas
Glass frames the world outside like a living canvas. We use triple-glazed, low-iron panels that eliminate the green tint found in standard architectural glass. The result is a view that appears to have no intermediary — guests frequently report the sensation of sitting in open air, protected but fully exposed to the landscape.
Each panel is coated with a spectrally selective film that blocks 70% of infrared energy while transmitting 92% of visible light. This means the glass keeps heat out without darkening the view — a critical performance characteristic in locations like Sedona and Big Sur where solar gain can be intense.
The frames are minimal — just 18mm of black anodized aluminum at each edge — and the mullions are engineered to align with natural sight lines so they disappear from conscious perception. When you look out of a Lookout Tower, you don't see the glass. You see the world.
