Over the next 12 to 15 years, we will be modernizing our buildings and apartments in the High-Deck estate step by step – for greater comfort, energy efficiency, and living quality. Plans include the renewal of roof insulation, windows, electrical systems, and plumbing.
Our goal: contemporary living, lower energy costs and a home where you can feel completely at ease.
This means we're not just investing in our buildings, but above all in good housing for the people who live there. And we're doing so in a socially responsible way. Their rent is capped after the modernization: rent increases are limited to €2.00/m² – and the affordability promise stands: net rent is capped at a maximum of 27% of household income.
