Hemlock House by Alexander Jermyn Architecture: Alpine Living Reimagined

Perched on a gently sloping site at the edge of a serene lake in California’s Sierra Nevada mountains, Hemlock House redefines the traditional alpine residence through innovative materiality and climate-conscious design. Facing some of the harshest winters in the continental U.S., where snow often buries homes to the roofline, and constant summer wildfire threats, the design team meticulously tested material resilience across a winter season before final construction. This careful process ensured durability, safety, and aesthetic quality throughout the year.

Exterior Architecture: Resilient, Sculptural Forms

The house’s exterior is defined by a striking composition of charred wood walls (shou sugi ban) suspended over a protective concrete base. The concrete serves as a fortified shell, analogous to a ship’s hull, defending the home from heavy snow loads and extreme weather. Above, the charred upper volume floats visually, creating a dramatic contrast against the winter snow while harmonizing with the surrounding forest.

A porous lakeside façade with sliding glass doors connects the interior seamlessly with the natural landscape, maximizing views and inviting sunlight into the home. The combination of concrete and charred timber not only enhances durability but also conveys a bold, contemporary interpretation of the alpine house typology.

Interior Design: Light-Filled, Connected Spaces

Inside, bleached hemlock and white-painted walls amplify natural light and create a serene, airy atmosphere. The main living and dining areas occupy the second floor, strategically oriented to capture panoramic lake views. Above the kitchen, a daylit mezzanine functions as an artist’s studio, offering creative inspiration from the surrounding landscape.

The ground floor accommodates practical needs with a garage, ski-tuning station, laundry, media room, and guest bedrooms. Thoughtful spatial planning balances community and privacy: built-in benches define intimate seating areas within larger communal spaces, while a bunk room comfortably sleeps 4–8 and features powered cubbies for remote work and study. Adjacent, a media room serves as a flexible overflow area for guests.

Collaborative Process and Pandemic-Era Construction

The bulk of construction occurred during the COVID-19 pandemic, creating a unique collaboration between the owner and architect. Traveling together for site visits, they developed a shared vision and close communication that shaped every aspect of the project, from material choices to interior layouts. This process resulted in a home that is both family-centric and architecturally sophisticated, blending resilience with refined aesthetics.
