Development Projects
We invest in cashflow-positive residential properties in and around Basel. These assets offer stable income and significant upside potential through modernization, ESG upgrades and targeted renovations. Through active asset management, we continuously enhance property performance.
A structured and capital-efficient financing approach is central to our strategy. With one of the strongest financing networks and deep expertise in financial structuring and corporate finance, we can access capital quickly and optimize capital costs. Our buy-and-hold strategy delivers long-term value creation and predictable cash flows.
