The company's active portfolio centers on premium residential properties in the most sought-after Heidelberg neighborhoods (Neuenheim, Handschuhsheim, Ziegelhausen, S\u00fcdstadt) plus the adjacent town of Br\u00fchl.

Technical specifications include KfW-Effizienzhaus 40 energy standard, air-to-water heat pumps, photovoltaic integration, and KNX or Gira One smart-home systems \u2014 standard German building-engineering practice rather than proprietary technology.

Revenue is generated through one-time property sales (new construction and existing stock) plus brokerage commissions at 2% plus statutory VAT.

The customer base consists of affluent individual buyers seeking high-end, individually designed residences, with no institutional or enterprise clients disclosed.
