Case Study
Glen Park, California | A Study in Light, Shape, and Simplicity
Introduction
A Modern Sanctuary Framed in Black
Atop a quiet hillside in San Francisco’s Glen Park neighborhood, a modern home reimagines traditional design through the lens of clarity and contrast. Rooted in restraint and elevated by elegant geometry, this residence—crafted by John Lum Architecture and built by Eastwood Construction—is a celebration of light, proportion, and quiet strength.
Framing Nature with Architectural Precision
Elevated Design, Inside and Out
The clean, minimalist lines of the window profiles complement the home’s California-modern architecture, allowing sunlight and structure to take center stage. Every window and door was selected not just for performance—but to act as a design element in its own right.
Skylights positioned over the main living area draw light from above, creating a sense of openness and upward movement that enlivens the entire space. These architectural windows invite the sky inside, changing the atmosphere throughout the day as light shifts and evolves.
At the core of this home’s bright and refined aesthetic is the thoughtful integration of Sierra Pacific windows and doors, which bring together modern form and high performance.
Seamless Indoor-Outdoor Transitions
To cultivate a strong connection between the interior and exterior, the design team employed a mix of Aspen casements, patio sliders, and an inswing door, ensuring each opening serves both a functional and architectural purpose.
The inswing door, framed in 023 Black powder-coated finish with matte black hardware, acts as both a sculptural and practical element—guiding residents seamlessly from inside to out while echoing the crisp lines of the home’s contemporary style.
The patio sliders create wide, generous passages that dissolve the barrier between home and garden. By flooding the space with natural light and framing curated views, they extend the interior experience to the outdoors and amplify the sense of space.
The half-round direct glaze window above the central dining space adds a moment of unexpected drama—filling the room with light from above and giving the angular modern geometry a soft, inviting focal point.
Interior Elegance: Urban Light Meets Modern Simplicity
Inside the Glen Park residence, serenity and sophistication come together in a home that reflects the vibrancy of California modernism while offering a peaceful urban retreat.
A Palette of Modern Warmth
- Anchored by soft neutrals, clean lines, and natural light, the interior is a masterclass in restrained elegance. White walls and blonde wood tones create a harmonious backdrop that allows architectural elements—like the striking black-framed windows—to shine.
- The use of natural textures and refined finishes lends warmth to every space, while carefully curated furnishings give the home a quiet sense of contemporary luxury.
Framing the Everyday: A Dining Space in the Spotlight
The kitchen and dining area are brought to life by a series of thoughtfully placed windows, including a signature half-round direct glaze unit that crowns the room with architectural distinction.
Flanked by Aspen casements and paired with a functional inswing door, this window composition draws the eye upward while bathing the space in daylight from multiple angles. The result is a dining experience that feels both open and intimate, turning everyday moments into something extraordinary.
A Light-Filled Escape: The Private Quarters
In the bedrooms and baths, windows continue to serve as sculptural design elements. Multi-slide patio doors in the primary suite allow for gentle cross breezes and visual access to the leafy outdoors, transforming the room into a light-filled haven.
Bathrooms, designed with clarity and calm in mind, echo the same principles—clean forms, soft finishes, and an emphasis on natural illumination.
Sustainability & Energy Efficiency
Behind the modern beauty lies serious performance. Sierra Pacific’s premium window and door systems contribute to the home’s sustainability and comfort with:
Energy-efficient glass packages, optimizing comfort without compromising views or aesthetics.
Precision-engineered insulation, reducing reliance on artificial heating and cooling.
Durable, low-maintenance cladding, ideal for withstanding California’s sun and seasonal shifts.
A Modern Retreat, Reimagined
Glen Park is more than a beautifully designed residence—it’s a refined response to the demands of contemporary urban life. Rooted in simplicity but rich in detail, the home is a testament to the power of light, proportion, and thoughtful design.
From morning sunrises filtered through custom-shaped windows to quiet evenings framed by expansive patio doors, this home embraces its environment at every turn—an elevated sanctuary for modern living in the heart of California.
A Modern Homestead for Today

Every design decision reflects a commitment to authenticity, craftsmanship, and sustainable living. And with Sierra Pacific Windows and Doors as a central component, the Barnhouse tells a story of openness, resilience, and elegance—one that will endure for generations to come.
