The price of top commercial property in London just keeps on rising .

Never mind houses in Belgravia, the price of top commercial property in London just keeps on rising too. To prove the point, along comes the sale by Swiss Re of Lord Foster's iconic, but for most purposes hopelessly impractical, "Gherkin" in the heart of the City for £630m. This is the most a single office block in the UK has ever fetched according to The Independent.

With London Commercial Property prices at an all time high, it seems that renting commercial office space is the way forward.
