Perfectly positioned in one of Seaford Heights' most sought-after pockets, 4 Harmon Street is not just another modern home-it's a statement of style, space, and sophistication. Built in 2022 and meticulously maintained, this two-storey showpiece stands out in every sense, offering luxury coastal living with exceptional design and unparalleled attention to detail.

From the moment you arrive, the striking faade and manicured gardens hint at what lies within-a home that delivers on both form and function. With its commanding street presence and premium finishes throughout, this property is truly in a class of its own in this tightly-held, high-demand suburb.

Crafted with growing families, professionals, and entertainers in mind, this four-bedroom residence boasts a flexible floorplan with multiple living zones, high ceilings, and an effortless indoor-outdoor connection. Oak flooring runs through the main open-plan living space, where large windows and stackable glass doors flood the home with natural light and invite the outside in.

At the heart of the home is a designer kitchen that will impress even the most discerning chef. Featuring stone benchtops, an integrated dining table, central island, and a generous butler's pantry, it's fitted with high-end Franke appliances including a 900mm gas cooktop and oven. The breakfast bar adds a casual touch, perfect for morning coffee or a quick bite on the go.

The luxurious master suite occupies its own sanctuary upstairs, complete with a private balcony offering sweeping ocean views-a daily reminder of the coastal lifestyle on offer. The ensuite is pure indulgence, with a freestanding tub, floor-to-ceiling tiles, and refined finishes. The other three bedrooms are all enormous with bedrooms two and three offering walk-in robes.

Step out to the expansive alfresco area-fully equipped with outdoor blinds, a built-in kitchen, and beautifully landscaped surrounds-creating the perfect backdrop for year-round entertaining or laid-back summer evenings. Beyond, the foundations for a versatile rumpus room are already in place, offering the opportunity to complete it in line with the original plans or reimagine the space as a pool area, shed, or self-contained granny flat (STCC).

Seaford Heights continues to grow in popularity, and it's easy to see why. With easy access to the award-winning McLaren Vale wine region, pristine Midcoast beaches, and a range of parks, walking trails, and schools, the location is the perfect blend of lifestyle and convenience.
