Double Diagonal Bay: Lakefront Luxury with Concierge Services in Horseshoe Bay

Welcome to Double Diagonal Bay — two side-by-side waterfront homes on Lake LBJ at 2518 and 2519 Diagonal, combined into one private compound. 8 bedrooms, 9 bathrooms, and accommodations for up to 19 guests across two distinct lakefront homes.
