Supamas has ordered prosecution against the contractor selling fake knockdown houses, citing discrepancies and breach of contract affecting over 50 victims with total damages exceeding 30 million baht. Initially, a CPB team has been dispatched for urgent investigation and legal action.
25 May 2026 GMT+7 Ms. Supamas Isarapakdi, Minister attached to the Prime Minister's Office, in her capacity as the supervisor of the Consumer Protection Board (CPB). She received a report from the CPB about citizens suffering from ordering knockdown houses from a contractor in Kalasin province, which did not meet the advertised standards. Victims transferred over 240,000 baht to the contractor, but near contract completion, they only received house frames. Victims said they saw a Facebook page advertising beautiful modern Thai-style houses that seemed credible, so they ordered knockdown houses at 170,000 baht each for two houses, making payments starting late March. More than two months later, work barely progressed, and the page became unreachable. Over 50 victims with total damages exceeding 30 million baht have been identified in this case.
Ms. Supamas said that upon learning of the issue, she immediately instructed the CPB to closely monitor the case. She assigned Mr. Lertsak Raktam, Director of Consumer Protection Division 3, responsible for contract matters, to urgently investigate and provide assistance to the victims. If consumers hire contractors to build new houses on their own land, this falls under the 2016 announcement regulating construction contracts for residential buildings, requiring contractors to prepare contracts as legally specified. However, knockdown houses are prefabricated homes that the seller moves to another site after construction, constituting a general sales contract outside that regulation. Nevertheless, the CPB remains committed to fully assisting consumers by exercising authority to prosecute on their behalf under Section 39 of the 1979 Consumer Protection Act.
For cases where consumers suffer from buying knockdown houses but do not receive them as contracted or the product is misrepresented, the CPB offers three forms of assistance: 1. Accept complaints and mediate negotiations between parties; 2. If mediation fails, the CPB will pursue civil litigation on behalf of consumers free of charge, so consumers do not bear costs or face court alone; 3. The CPB oversees fair contract terms in construction hiring cases.
“Since 2022, the CPB has received 99 complaints related to knockdown and prefabricated houses, resolved 68 cases, and 31 remain ongoing. The government under Prime Minister Anutin Charnvirakul reaffirms its commitment to support all consumers, ensuring they are not exploited or deceived in any form.”
In knockdown house cases, contractors must clearly specify details including structure, house design, materials used, sales contract, warranty, payment schedule, and delivery date. Consumers should verify the company's credibility, construction timelines per contract, and material quality matching advertisements. If these are not met or consumers suffer damages, they can file complaints via the CPB hotline 1166, OCPB Connect app, the website ocpb.go.th, or Damrongtham Centers nationwide.
