Heimstaden is using ChatGPT Enterprise and Codex for virtual property imagery, listing review, environmental-risk analysis and contract workflows, while employees retain responsibility for decisions and approvals.
AT A GLANCE
Key points
- ChatGPT Enterprise adoption reportedly reached 50% of employees within two to three months.
- Virtual property-image production reportedly fell from about €50 to less than €0.10.
- Codex was used to assess 20,112 property assets and more than six million data rows.
What is changing?
According to OpenAI’s November 3 customer story, European residential operator Heimstaden is expanding ChatGPT Enterprise and Codex across letting and property operations. The company says 50% of employees were using ChatGPT Enterprise within two to three months of its September 2025 rollout.
In the Netherlands, the cost of producing a virtually staged property image reportedly fell from about €50 to less than €0.10, with Heimstaden estimating annual savings potential of €130,000 in that market. AI also supports pricing recommendations, listing copy and quality review, while employees approve live advertisements and commercial decisions.
Heimstaden says Codex helped assess environmental risks across 20,112 property assets and generate more than six million useful data rows. It is also rolling out a procurement platform connected to Outlook, SharePoint and Teams, while the MCP-enabled Amplio Estate system remains under development. The reported outcomes come from a Heimstaden and OpenAI case study rather than an independent evaluation.
