Last Listing description (November 2025)

Elevated and elegant, this striking three-level residence in Seaview Downs offers a rare combination of grand proportions, warm character, and versatile family living with coastal views. Perched proudly on a commanding 830sqm (approx.) corner allotment, this expansive family home is as rich in history as it is in lifestyle appeal. Originally constructed in the 1970s as the local doctor's surgery, this unique residence has been lovingly transformed by its current owners - who added a second level and reinvented it into the spacious, light-filled family haven it is today.

From the street, the home makes an immediate impression. A wide frontage provides ample off-street parking for a boat, caravan or trailer, complemented by a double carport and additional garage/shed at the rear. The elevated façade is framed by lush greenery, while the sweeping balcony captures breathtaking sunsets and uninterrupted coastal vistas.


Designed with functionality and flexibility in mind, the home offers five generous bedrooms and two beautifully renovated bathrooms across two levels. Upstairs is an entertainer's dream with soaring ceilings, open-plan living and dining, and a cosy slow combustion heater adding warmth and charm. The entire space spills out to the balcony, creating a seamless connection to the outdoors and those spectacular sea views.

The master suite on the upper floor offers a private retreat with its own ensuite and walk-in robe. Downstairs, the heart of the home continues with a contemporary kitchen featuring stainless steel appliances, stone benchtops, and a practical servery window to the outdoor entertaining area - perfect for weekend barbecues or relaxed family dinners.

A central bathroom with a large bath, modern fixtures, and warm tones services the remaining bedrooms on the lower floor, while ceiling fans throughout ensure year-round comfort. And for those working or studying from home, a dedicated third-floor office with adjoining storage provides peace and privacy.

Step outside to discover a private and tranquil entertaining space beneath the large undercover pergola, set against natural stonework and mature gardens. There's even a patch of lawn and veggie beds ready for your home-grown produce.

Families will value the highly sought-after school zoning to Seaview Downs Primary School and Seaview High School, along with the convenience of nearby local shops, cafes, and entertainment options at Westfield Marion and the cosmopolitan Glenelg precinct. Public transport is within easy reach, making commuting to the city or coast a breeze. Complete with a solar system for energy efficiency, ample storage inside and out, and a flexible layout ideal for growing or multi-generational families, this one-of-a-kind property perfectly blends history, modern comfort, and lifestyle excellence in the heart of seaside Seaview Downs.
