Overview

Property Description

Some homes offer more than square footage—they offer room to live the way you want. 1801 Sun Lake includes a rare combination of space, character, and outdoor living in one of Round Rock's most distinctive neighborhoods! Flexible living spaces, extraordinary outdoor amenities, and the natural beauty of Tonkawa Springs come together in a truly special setting. Nestled among mature trees and spacious homesites in Tonkawa Springs, this beautifully updated home offers the flexibility, comfort, and outdoor amenities that are increasingly difficult to find. Inside, you'll discover generously sized rooms and an exceptionally versatile floorplan featuring four bedrooms plus two additional flex rooms—ideal for home offices, guest rooms, a fitness studio, craft room, or whatever suits your lifestyle. Abundant storage adds everyday practicality, while thoughtful improvements bring both beauty and functionality. Gorgeous acacia wood floors, energy-efficient triple-pane vinyl windows, and a chef-inspired kitchen with a Fratelli Onofri double gas range, built-in wall oven, and microwave are just a few of the highlights. The spacious gameroom adds distinctive character with a ceiling crafted from reclaimed Camp Mabry wood. Step outside and discover your own backyard retreat! A sparkling in-ground pool, expansive composite deck, built-in stone firepit, and cabana with outdoor bar and BBQ create an exceptional setting for year-round entertaining or simply unwinding at home. Beyond the property, Tonkawa Springs offers a setting unlike typical suburban neighborhoods, with spring-fed ponds, abundant wildlife, towering trees, oversized lots, tennis/pickleball courts, and a welcoming sense of community. Enjoy the tranquility of this established neighborhood 10 minutes of highly rated schools, great restaurants, shopping, and major employers.
