View key findings of the Commercial Development Activity research report.

Key findings:

• Savills survey data indicated a moderate expansion of overall commercial development activity in December, extending the current period of growth to five months.
• Private sector development underpinned the expansion in December, while public sector activity dropped further.
• Just under 23% of commercial developers reported a rise in activity in December, while 19% indicated a fall.
• At +3.6%, down from +9.2% in November, the resultant Total Commercial Development Activity Index signalled the slowest rate of growth since the start of the upturn in August.

Commenting on the December survey, Mat Oakley, Head of Savills' Commercial Research department said: "As vacancy rates begin to show signs of peaking in some markets it is clear from this month's survey that developers' optimism is remaining resilient. There are still risks to be faced in 2010 but we are definitely past the worst."
