Thailand's custom home-building market is projected to grow 4–5% to 200 billion baht in 2025, supported by affluent consumers, particularly in Isan (Northeast), driven by improved infrastructure like the M6 motorway. Luxury homes (20M+ baht) surged 53% year-on-year, indicating strong demand among high-net-worth individuals despite broader economic headwinds including 3% GDP growth and inflation pressure. This segment resilience suggests sustainable demand from buyers with land, savings, and purchasing readiness.
