Dated Urban Appeal
With a construction date back in 1970, this timeworn apartment in the west of Hamburg spans 95 m². With 3.5 rooms and a balcony, the property offered basic functionality but lacked modern features and energy efficiency, which is typical for that construction era.
Eco-Driven Living
Through a comprehensive modernization following the Eco-Standard, the apartment now features smart thermostats, optimized heat circulation via a floor station, a smart home controller, and energy-efficient LED lighting. These upgrades are likely to achieve a 25% reduction in energy consumption, cut utility costs by 1€/m², and deliver an impressive 16.35% return on CAPEX investment. The upgrades enhance sustainability and comfort, creating a modern living space that meets standards and adds value.
