4303 Island Ave, Austin, TX 78731

The Marque at Island Cove on Lake Austin. For those who seek waterfront living yet covet privacy and quiet, there simply isn't a better choice. Located on a paradisical acre replete with waterfall, grotto, gorgeous cypress trees and an amazing resort style pool with lazy river this deeply curated home leaves only one question, "why leave"? It blends entertainment and every day living seamlessly. Located in The Island, coveted by creatives and influencers, it's also minutes to downtown and every key business location in Austin. The fully integrated layout of the home fits multiple lifestyle needs with three wings of bedrooms centered around living spaces, kitchen and dining spaces. The exterior living spaces combine with the one-of-kind pool offering a stone cabana swim-up bar, seating integrated into the pool, and a connecting winding lap pool to the Jacuzzi; all steps from interior living areas. The state of art theater whisks you away to the Golden era of Hollywood yet is just a staircase away from the kitchen. The grand coffered entrance flanked by majestic winding antebellum marble staircases lead right to the comfortable master with multiple balconies as well as a private home office suite where one’s creativity will surely be inspired. The home is a continuous display and appreciation of supreme quality. The grand architecture gracefully meets artisan carved slabs, master carpentered arched windows, groined brick ceilings, gorgeous hand-laid mosaic tile covering 100% of all pool surfaces and true two-piece European tile roof. This level of curation, quality and architecture simply cannot be re-created nor matched at this value. Fully self-sustained casita for in-laws or friends next to the two-slip boat dock with spaces for jet skis. Savant Home Control System for full automation of lighting, audio, video, security and pool functions. Elevator for all 3 levels of home.

Lake Austin is Austin's most exclusive waterfront corridor - 22 miles of constant-level shoreline in 78732, 15 minutes from downtown. Waterfront homes start around $4M and trophy lots with 200+ feet of flat shoreline trade at $15M-$35M+. The lake is controlled by Tom Miller Dam, which maintains consistent water levels year-round - the key advantage over seasonal Lake Travis.

This is one of Austin's thinnest markets. Roughly 22 miles of total shoreline, and at any given time only 3-5 homes are actively listed. Many of the best lots trade privately through agent relationships before they ever reach the MLS. The finite supply creates a structural price floor that insulates Lake Austin from broader market cycles.

Buyers here want water access as daily life, not a weekend plan. Morning paddleboard, afternoon ski run, burgers at Ski Shores by boat, sunset from your own dock watching Hill Country ridgelines. The practical side matters too: you are inside Austin city limits with full services, 15 minutes from downtown, 10 from the Domain.

Four Seasons Private Residences is under development on 145 acres with 188 planned homes - the first significant new inventory since the lake was established. Eanes ISD and Leander ISD serve different sections of the corridor, both with strong school ratings.
