Real estate brokerage firm Aengevelt has successfully brokered the sale of an approximately 4,100-square-metre plot on Froschkönigweg in Düsseldorf's Flingern district under an exclusive mandate. The seller of the site is Deutsche Telekom AG. The purchaser, a Düsseldorf-based property developer, intends to build new housing on the property. The parties involved have agreed not to disclose the purchase price.
The site currently accommodates a technical building and a bungalow. The existing technical operation is not to be abandoned as part of the realignment, but will be relocated within the plot itself to pave the way for urban redevelopment.
Structured planning review and transaction process
The actual launch of marketing was preceded by an in-depth review of planning and development feasibility by Aengevelt. On this basis, suitable property developers were approached directly. The mandate was awarded in October 2025. Following negotiations, the notarial purchase contract was completed on 30 September 2026.

Portfolio strategy and unlocking inner-city land reserves
Rochus Weidner, who oversaw the transaction on behalf of Deutsche Telekom AG, explained that the company-owned real estate portfolio is continuously assessed regarding operational necessity. Where this requirement no longer applies, the company pursues targeted disposal strategies. The planned residential use on Froschkönigweg contributes significantly to meeting existing demand in Düsseldorf's tight housing market.
Oliver Lederer, Head of Investment & Development at Aengevelt, stressed the relevance of such projects for the state capital. There is an acute shortage of housing in Düsseldorf, while developers act cautiously given scarce land and complex viability calculations. In this context, surplus infrastructure sites from large corporations represent one of the few remaining reserves that can still be mobilised. By clarifying planning law and ground conditions at an early stage, a former technical facility can be successfully converted into marketable building land.
