How will the Comprehensive Spending Review redraw the Lewisham housing map?

Yesterday's Comprehensive Spending Review cut the budget for building affordable homes by approximately 50%.

However, we find the subject completely bewildering, so please feel free to tell us what impact these changes are likely to have.
