Heimstaden uses OpenAI tools to cut Dutch property-image costs by more than 99%

In the letting workflow, AI now supports pricing recommendations via tools built in ChatGPT Sites, styles property images, writes apartment descriptions, reviews live advertisements against quality standards and generates market feedback for dynamic pricing. Heimstaden said the cost of producing a virtually staged property image in the Netherlands fell from about €50 to less than €0.10, with estimated annual savings potential of €130,000 in that market alone. The saving sits within a broader redesign that coordinates pricing, advertising, listing review and market feedback.

For environmental-risk analysis, sustainability analyst Julia Erlandsen used Codex to find, clean and standardise data across public sources and create repeatable processing pipelines. OpenAI reported the project assessed 20,112 assets and generated more than six million rows of useful data. Estimated delivery effort fell from five people for a year to two people for two months, and Heimstaden avoided external consultants. ChatGPT Enterprise launched at Heimstaden in September 2025; OpenAI said half of employees were using it within two to three months. A Procurement Intelligence Platform combining workflow automation with OpenAI models via APIs is being rolled out across Outlook, SharePoint and Teams. Heimstaden is also co-developing Amplio Estate, a property-management system intended to support AI-powered workflows through MCP, with the long-term ambition of increasingly self-operating buildings where AI anticipates needs and coordinates work under human oversight.
