London offers investors best returns for major office renovation

The renovation of offices can provide investors with the best opportunity to improve the income of their older buildings. This is particularly pertinent in European cities where there are large volumes of old office buildings that offer enormous potential to be extended or redesigned

"In London, there has been a growing trend for older offices with character and in good locations to be refurbished."

In other cities, a program of minor renovation would be a better strategy to gain the strongest returns. For investors taking this approach, Madrid and London were judged to be the most attractive, whilst Shanghai and Singapore also made it into the top five.
