12317 176th Avenue SE Renton, WA 98059

Custom built in 2006 with full Insulated Concrete Form construction; this residence situated between Issaquah, Newcastle, and Renton was designed for lasting quality and exceptional energy performance. ICF walls deliver superior insulation, structural resilience, and a remarkably quiet interior, placing this home among the top five most energy-efficient in a neighborhood of over 100 homes. Hydronic radiant heat warms every finished level: consistent comfort through every season without supplemental cooling in a typical Pacific Northwest summer. Vaulted ceilings and generous windows fill the great room with natural light, while custom handcrafted millwork throughout reflects the care behind the original build. Recent updates include new quartz countertops, new great room flooring, and new carpeting. The finished lower level adds flexible living space and direct access to the heated shop with its own bay door. Outside, the nearly half-acre lot provides space and privacy increasingly rare this close to Eastside conveniences. Dedicated RV parking, two well-maintained sheds, and separate wood storage offer functional outdoor space most properties cannot match. A standing seam metal roof and full ICF construction reinforce the long-term, low-maintenance character of the build. No HOA, within the highly regarded Issaquah School District. A rare opportunity to own a custom residence where this level of construction quality and energy efficiency is built into every wall.
