4 bed, 3 bath, 3,326 sqft on 3.05 acres in Spring Branch. Spring Branch, TX 78070. $1,890,000. Comal ISD.
Luxury Hill Country living unfolds in the gated Peninsula at Mystic Shores community on 3.05 acres, where this custom (architect designed) residence offers 4 bedrooms, 3.5 bathrooms, and 3,326 square feet of refined living space in a private, resort-style setting. Soaring ceilings and abundant natural light define the open-concept main living area, anchored by a stone fireplace flanked by custom walnut cabinetry and a wood ceiling that adds warmth and architectural character. The kitchen is designed for both function and entertaining, featuring a large quartz island, convection cooktop, built-in appliances, and generous storage. Adjacent but hidden from main view is a butler's kitchen with separate gas cooktop, stove, dishwasher and refrigerator. A private study provides flexible space for work, creativity, or quiet retreat. The split-bedroom layout enhances privacy, with a spacious primary suite offering a spa-inspired bath complete with heated floor, dual vanities, a walk-in shower, soaking tub, and oversized his and her closets. Secondary bedrooms are well-appointed with ample storage and access to beautifully designed bathrooms. Outdoor living extends to both a covered patio as well as a separate screened porch overlooking the Guadalupe River and peaceful Hill Country surroundings, creating an ideal space for relaxing or entertaining. The Peninsula at Mystic Shores offers gated access along with resort-style amenities including two pools, pickleball and tennis courts, parks, trails, and private access to Canyon Lake. This home is on the Guadalupe River, convenient to shopping, dining, and top-rated Comal ISD schools and delivering a rare combination of luxury, privacy, and Hill Country lifestyle in one of the area's most desirable communities.
Direct access to the Guadalupe River and Canyon Lake sits 200 feet from your back porch at 352 Arthur Court in Spring Branch's gated Peninsula at Mystic Shores community. This isn't a home with a view of water - it's a basecamp for launching into it.
The 3.05-acre property gives you room to store gear, stage equipment, and maintain the infrastructure an active lifestyle demands. A 3-car garage handles vehicles and toys. The 3,326-square-foot residence built in 2019 operates around one principle: the outdoor life comes first, and the house supports it. Soaring ceilings and open floorplan keep sightlines clear to the screened porch overlooking the river. A primary suite with spa bath and heated floors sits on the main level, so you're never far from the action. Secondary bedrooms and a flex study handle the logistics - guests, gear storage converted to work space, climate-controlled storage for seasonal equipment.
The kitchen's dual setup (main kitchen plus butler's kitchen with separate cooktop) handles the refueling phase efficiently. Feed the crew fast. The quartz island and built-in appliances are designed for volume - you're feeding paddlers, hikers, and boat crews coming off the water. A hidden pantry keeps supplies organized. High-speed internet means you can work from the property when conditions are perfect.
Access defines everything here. Canyon Lake offers lake activities year-round. The Guadalupe River corridor stretches north and south with established paddling routes and swimming holes. Peninsula at Mystic Shores includes resort amenities - two pools, pickleball and tennis courts, maintained trail systems - but the real draw is private access to water. You're inside the gated community but outside the noise, on 3 acres with moderate tree coverage providing natural screening. Rebecca Creek Elementary, Mountain Valley Middle, and Canyon Lake High all serve Comal ISD families in the area.
Spring Branch's location puts you 45 minutes from Austin's central employment core via TX-45, but that commute trade-off becomes irrelevant when your commute is a 30-second walk to launch a kayak. This is the property where weekends extend into weekdays, where "getting away from it" means stepping into your backyard. The rush isn't the lifestyle upgrade - it's the immediate proximity to the one you've already chosen.
