Habitat for Humanity Thailand and its partners build, repair or rehabilitate homes with families living below the national poverty line as well as vulnerable groups.

Construction costs are brought down through volunteer labor, gifts-in-kind from corporate donors and donation of soil for land reclamation from the local government, among others.

The 26 December 2004 Indian Ocean tsunami was known as one of the most devastating disasters of recent times. The tsunami was caused by a 9-magnitude undersea earthquake that struck off the west coast of Sumatra, Indonesia. More than 230,000 died and 1.7 million people were displaced as the tsunami-affected more than a dozen countries from Thailand to Madagascar.
Habitat for Humanity Thailand started its tsunami-recovery work in Phang Nga province in 2004, the area hardest hit by the tsunami, then expanded to Phuket, Ranong and Krabi. It had housed more than 700 tsunami-affected families. As part of the transition to a regular program, Habitat for Humanity Thailand had begun recruiting families to join a Save & Build microfinance housing scheme. In addition to new houses, the program will include repairs and rehabilitations.
Following the devastating floods in 2011, Habitat for Humanity Thailand distributed cleanup kits and emergency shelter kits to nearly 4,000 families in 11 provinces. In addition to over 1,400 families who rebuilt their homes, 32 schools were rehabilitated and four multipurpose buildings were built in Ayutthaya and Phitsanulok provinces. In 2017, Habitat for Humanity Thailand distributed hygiene kits containing items for cleaning up houses to affected families in Trang province in the south. The longer-term focus is on helping disaster-affected families to rebuild or rehabilitate their houses.
In 2021 and 2022, in response to the COVID-19 pandemic, Thailand distributed hygiene kits (e.g., face masks, soap, alcohol swipes, etc) to vulnerable families and communities in Nonthaburi, Pathum Thani, Chacheongsao, Ayutthaya, and Suphanburi provinces.
