There are certain moments when discovering a unique piece of architecture completely changes your understanding of what's architecturally possible. This is exactly what happens when encountering an extraordinary 1965 A-frame house designed by Sandler-Kilburn Architects, nestled deep within the forested landscape of Issaquah, Washington. While the majority of Pacific Northwest residential architecture from the 1960s embraced the popular rustic cabin aesthetic that dominated the region, these visionary architects chose to pursue an entirely different creative direction. They successfully created one of only twelve original Mirrormont homes, utilizing steel and glass construction materials instead of the conventional heavy timber approach that was expected during that era. The remarkable result is an absolutely stunning architectural achievement that continues to captivate viewers nearly six decades after its completion. The impressive 1,950-square-foot structure sits prominently on more than one acre of pristine forest land near the base of Tiger Mountain, establishing an extraordinary dialogue between bold industrial materials and the ancient evergreen trees that surround the property. This unique conversation between modern construction techniques and natural forest elements works brilliantly on every conceivable level. The architects demonstrated exceptional skill in handling their chosen material palette throughout the entire project. Rather than attempting to artificially blend into the natural surroundings with fake rustic elements or forced traditional styling, they made the bold decision to embrace steel framework construction paired with dramatic floor-to-ceiling windows that effectively erase the traditional boundaries between interior and exterior spaces. Inside the home, custom-crafted walnut cabinetry beautifully frames the kitchen area, introducing precisely the right amount of natural warmth without overwhelming the space with excessive wood-themed elements. The centerpiece of the living area features a striking Tulikivi soapstone fireplace that serves as both an incredible sculptural focal point and an efficient heating system for the entire home. The spatial planning throughout this A-frame residence is absolutely excellent, particularly for those who appreciate compact living executed with exceptional skill and attention to detail. The distinctive A-frame architectural shape naturally creates soaring ceiling heights that make the interior spaces feel significantly larger than the actual square footage would suggest. Two well-appointed bedrooms located on the upper level are connected by an elegant floating staircase design that maintains perfect visual flow throughout the entire living space. The primary bedroom suite becomes a perfect private retreat, featuring a luxurious Japanese soaking tub that transforms everyday bathing routines into something approaching a meditative experience. This type of refined architectural detail exemplifies the kind of thoughtful design that elevates the entire living experience to a higher level. The main floor of the home flows seamlessly from the living room area to the dining space and then into the kitchen, before extending outward onto an impressive deck that reaches directly into the forest canopy, creating the sensation of living in an elevated treehouse designed specifically for adults. Standing on this extended deck provides the incredible feeling of being suspended among the towering trees while maintaining complete connection to the interior of the house. Most people automatically assume that homes built in forest settings must necessarily look like traditional log cabins or rustic retreats, but Sandler-Kilburn Architects clearly demonstrated that modernist architectural principles can not only survive but actually thrive in heavily wooded natural settings. Their innovative use of steel and glass construction techniques actually weathers better than many traditional building materials while simultaneously creating a timeless aesthetic appeal that still looks remarkably fresh and contemporary today. The gracefully curved roofline positioned over the main entrance adds beautiful sculptural visual interest while serving the completely practical function of efficiently shedding rainwater in the Pacific Northwest's notoriously wet climate. The real estate market has clearly recognized and validated the architectural significance of this exceptional property. The home's value increased dramatically from $875,000 in 2016 to its current asking price of $1.8 million today, which provides clear evidence of how people are finally beginning to recognize and properly value quality mid-century modern architectural design. This remarkable Issaquah A-frame house perfectly embodies everything that makes fearless residential architecture so compelling and enduring. Sandler-Kilburn Architects successfully created something that genuinely honors its pristine forest setting without pandering to architectural clichés or expected design conventions. They chose to use construction materials that age beautifully while maintaining their distinctly modern edge and contemporary appeal. The fact that architecture enthusiasts and design professionals are still discussing and celebrating this house nearly sixty years after its original construction clearly demonstrates what can be achieved when architects prioritize spatial quality and honest material usage over temporary trends and fashionable styling. For anyone who truly appreciates clean, simple yet powerfully effective architecture, this steel and glass architectural gem hidden in the Washington woods represents essential viewing and study. The home stands as a testament to the enduring power of thoughtful modernist design principles applied with skill and vision to create something that transcends its era while remaining perfectly suited to its natural environment.
