AI and cloud company MegazoneCloud said on Tuesday it completed a pilot project with major South Korean architectural design firm Heerim Architects & Planners to develop an "architectural code review AI agent system".

MegazoneCloud said it enabled AI to carry out preliminary work such as required reviews of laws and regulations before design work, cutting tasks that previously took 3 to 5 days to within 30 minutes.

It stressed that it built the service in the Seoul region using Amazon Bedrock Agent Core for the first time in South Korea's architecture sector, helping address regulatory concerns over overseas transfer of sensitive data.

According to MegazoneCloud, when users upload architectural design documents or competition guidelines as PDF or image files, the system links in real time to open APIs from the Ministry of Government Legislation and the Ministry of Land, Infrastructure and Transport's spatial information system. It automatically reviews 38 items across 8 categories, including zoning, building coverage ratio, floor area ratio, sunlight rights, evacuation facilities and eco-friendly certification, and outputs compliance status and legal grounds for each item.

It extracts project information such as use, scale, location and area from design documents, automatically matches it with district unit plan notices for the area, and integrates the results into the code review. It also highlights the relevant location in the uploaded file along with the legal provisions and can export the results in Excel format.

The system is implemented as a multi-agent structure in which agents with different roles work step by step under a supervisor agent to complete code reviews automatically. The supervisor agent oversees the entire pipeline, with 5 specialist agents running sequentially for PDF preprocessing, project analysis, district unit plans, legal review and design standard analysis. The company said technical optimisation reduced the cost per code review run by 86 percent from the early development stage.

MegazoneCloud is a partner selected for Amazon Web Services' generative AI cooperation programme, the Generative AI Partner Innovation Alliance, and it carried out the project based on cooperation with AWS.

Jin-ho Jeong (정진호), a leader at MegazoneCloud, said the pilot proved in a real environment that AI agents can complete complex professional tasks beyond simple Q&A. He said that as it confirmed multi-agent adoption is particularly effective in areas with complex regulatory systems such as building codes, the company will more actively push to expand into similar industries.
