Acting as sole agent, brokerage firm Aengevelt has advised on the sale of a property on Froschkönigweg in the Flingern district of Düsseldorf. The vendor of the approximately 4,100 square metre site is Deutsche Telekom AG. The buyer, a property developer based in Düsseldorf, intends to build new residential units on the land. The contracting parties have agreed not to disclose the purchase price.
The plot currently still accommodates a technical building and a bungalow. However, the existing technical use will not be abandoned, but relocated within the site itself in order to free up the remainder of the land for future residential use.
Structured preparation and transaction process
Prior to the official launch of marketing, Aengevelt analysed the structural options for the location and identified suitable development partners in the market. The marketing mandate was awarded to the advisory firm in October 2025. Following the completion of reviews and negotiations, the purchase contract was notarised on 30 September 2026.

Potential of surplus corporate real estate
Rochus Weidner, who oversaw the transaction on behalf of Deutsche Telekom AG, explained the group's approach: the company's own real estate portfolio is continuously reviewed for operational necessity. If there is no longer an internal requirement, economically sensible disposal strategies are pursued. The planned creation of housing on Froschkönigweg makes a noticeable contribution towards meeting demand in Düsseldorf's strained housing market.
Oliver Lederer, Head of Investment & Development at Aengevelt, emphasised the significance of such conversion sites. Düsseldorf faces a noticeable shortage of homes, whilst new-build schemes are currently rarely realised given scarce plots and demanding cost calculations. Corporate infrastructure land that is no longer operationally necessary forms one of the few remaining land reserves. When planning law and ground conditions are reliably clarified in advance, former technical sites once again become sought-after development land for builders.
