18 Trelawney St, Thornleigh is a 4 bedroom, 3 bathroom House with 2 parking spaces and was built in 1970. While the property is not currently for sale or for rent, it was last sold in April 2025.
Infused with a calming sense of luxury, the Hamptons elegance balances a coastal ambience within a home curated for harmonious family cohesion and outdoor living. Sophisticated refinement subtly shines through design elements accented with textural warmth, French Oak engineered flooring, herringbone details, and lighting fixtures culminate throughout a dual-level layout anchored by a stunning kitchen.
Wrapped in outdoor connectivity, lounge and dining spaces cascade through stacking glass sliders to a garden designed for alfresco enjoyment. Magically sitting under 3m high ceilings, a rumpus room fitted with walls of built-in cabinetry and a discreet wine bar opens to an entertaining deck surrounded by tropical gardens and a refreshing salt-water pool.
Effortless and contemporary bedrooms with integrated wardrobes flow throughout a private upper level, a family bathroom embodies modern timelessness with a freestanding bathtub, walk-in shower, and vanity with a fluted basin. An ensuite transforms the main bedroom into a sacred parent's retreat. Prestigiously positioned close to an array of sought-after schools and walking distance of Thornleigh Marketplace and the train station.
