Unlocking Opportunity: What the National Housing Bank Means for the Future of UK Housing
The UK Government’s recent announcement of a new National Housing Bank (NHB) marks a pivotal moment in the country’s housing strategy. With a mandate to unlock over 500,000 new homes, the NHB is set to become a cornerstone of long-term investment in housing delivery, particularly in areas where viability has historically stalled progress.
At Drees & Sommer UK, we welcome this bold step forward. As a consultancy rooted in sustainable development and strategic delivery, we see the NHB as a catalyst for innovation, collaboration, and regeneration across the built environment.
