For truly high land prices, try the area in and around Siam Square, where 2 million baht will buy you one square wah. The average land prices in the CBD rose 6.4% last year, with the highest price recorded at 1.91 million baht per square wah in 2015. "As soon as they think a condo project developed on the plot can be sold at a high price, they will buy despite such high land prices." According to property consultant Agency for Real Estate Affairs (AREA), land prices in Greater Bangkok will rise by 4% on average this year, the same as last year. Land prices on Rama IV Road are around 400,000-500,000 baht per sq w. AREA estimated they would rise to 1 million baht per sq w once the Grey Line between Rama III Road to Watcharaphol started construction.
