Sam Conlen and Tara Witham proudly present 18 Mason Avenue, Happy Valley on the market.
Perfectly positioned in one of Happy Valley's best pockets, this versatile family residence offers a unique blend of indoor flexibility and outdoor entertainment. Set on a generous 637sqm allotment in a peaceful, established street, this home is the ultimate "move-in ready" opportunity for families who value space, lifestyle and a sense of community. Directly across from a beautiful local playground and reserve, your extended backyard is right across the road.
The floor plan is exceptionally flexible, headlined by a spacious separate rumpus room or fourth bedroom if you'd prefer. This standalone space is perfect as a teenage retreat, a home office, or a gym/pool room. Inside the main residence, you'll find three comfortable bedrooms (the master and second with built-in robes) serviced by a neat central bathroom with a separate toilet for family convenience. The living zones include a light-filled lounge that flows effortlessly into a dedicated sitting room and a central kitchen/meals area.
The kitchen is a chef's delight, complete with a walk-in pantry, gas cooking, a dishwasher and a stainless steel wall oven, ensuring it truly remains the heart of the home. However, it's the outdoor space that steals the show. A massive undercover entertainment area provides a grand stage for year-round gatherings, overlooking a backyard filled with established fruit trees. With double-gate access at the front and a secure, fully fenced perimeter, there is plenty of room for kids and pets to play safely.
Location is the hallmark of 18 Mason Avenue. Being on the "Hub" side of Happy Valley, you are within a short walking distance of the Aberfoyle Hub Shopping Complex, featuring supermarkets, restaurants and the Hub Interchange for easy city commuting. Nature lovers will appreciate the proximity to Thalassa Park and the Rose Garden walking trails, while the Happy Valley Reservoir is just minutes away for kayaking and weekend adventures. Zoned for Aberfoyle Park High School and just moments from Happy Valley Primary, this home offers a "walk-to-everything" lifestyle that is rare to find.
