Beach Box 28 on Shelley Beach in Portsea is currently listed for sale with an asking price between $910,000 and $1 million.  This valuation surpasses Melbourne's median house price of $895,000, highlighting the premium nature of such beachfront properties. 

The high valuation is influenced by several factors:

Scarcity and Demand: Beach boxes in this area are rare and highly sought after, driving up their market value. 

Construction Quality: Unlike typical weatherboard structures, Beach Box 28 is constructed from masonry blocks, enhancing its durability and appeal. 

Accessibility: Its proximity to a public park allows for easy access by car, adding to its desirability. 

Recent sales of similar properties in the vicinity support this valuation. For instance, a nearby beach box sold for approximately $950,000 in early 2024. 

Given these considerations, the asking price for Beach Box 28 appears to align with current market trends for similar properties in the area.
