A former market garden with a 1920s brick and tile home and overgrown glasshouses in Mangere sold at auction this week for $4.7 million - almost $3.5m over its council valuation.
Twenty-two groups registered to bid on the flat, sunny 1.163 hectare Favona site at auction - and most were developers looking to make a pretty penny.
The large site has space for 25 houses, which could rise to 35 under proposed Unitary Plan changes.
With a median value of $622,000 per home the value of the site would be upward of $21m - not taking into account build or development costs.
Harcourts agent Pauline Anderson said the sale price was outstanding but added that land for quality developments in South Auckland was scarce and hotly in demand.
