LONDON--Buying trophy commercial properties in London has been getting more competitive because of a new group of investors: the global superrich.

Wealthy individuals have long sought their own slices of London real estate, from glitzy mansions to broad office blocks. But recently, their appetite for paying hundreds of millions for a single office building has been growing.

Before the financial crisis, paying that much for a single building "was normally the preserve of institutional capital," said Damian Corbett, head of central London capital markets at broker Jones Lang LaSalle Inc. "Now, individuals are playing with the big boys at the global funds."

For example, in December, Spanish billionaire Amancio Ortega bought 6 St. James Square, headquarters to global mining giant Rio Tinto PLC, for GBP265 million (about $400 million).

Brazilian billionaire Joseph Safra in November bought 30 St. Mary Axe, nicknamed the Gherkin, for around GBP725 million. The final bid far outstripped the GBP650 million asking price. Of the four final bidders, Mr. Safra was one of two high-net worth individuals, people familiar with the deal said.

The pursuit of London commercial property by the global rich is a sign of the growing number of billionaires whose personal fortunes are equivalent to the size of institutional investment funds. It also shows that these investors, as well as traditional players in the investment world, are being pushed to "look for long-term stores of wealth," said Bill Hughes, head of real assets at Legal & General Investment Management, one of the largest institutional property fund managers in the U.K.

London real estate offers swaths of what these investors look for: laws that tend to side with property owners, an expanding economy, and a market where it is easier to trade in huge, expensive assets than almost anywhere else in the world. London property also has tended to rebound relatively quickly from recessions, and some experts believe that it will hold its value better in future downturns because of the growing number of players in the market.

However, the superrich still face the same risks as other global property investors. London is in the midst of a property boom. While analysts remain generally positive on the near-term outlook, there is uncertainty about how long the upswing will last.

The central London market saw a record GBP21 billion worth of commercial property sold in 2014, up from GBP20 billion in 2013, according to data from Savills, a leading real estate services firm. Of this, private buyers accounted for nearly $4 billion, similar to 2013, it said.

Private investors, often through family offices or companies, spent on average GBP40 million per asset in 2013 and 2014, according to broker JLL. The average from 2008 to 2012 was GBP29 million. Analysts note that tracking such deals is difficult, with many done privately or through obscure companies and funds.

Private investors aren't just targeting London. The exclusive group accounted for about a quarter of all 2014 property deals globally, including residential investments, according to broker Knight Frank. They're also fueling demand in cities like Paris, New York, Dubai and Hong Kong.

Away from London, Mr. Safra also nabbed the WINX office tower in Frankfurt last year for $436 million. Mr. Ortega bought the Renaissance Plaza in Toronto for $226 million.

Increased competition from wealthy investors and others in London has helped push average office yields to 4.8% in the fourth quarter, lower than before the financial crisis, according to data from MSCI's IPD U.K. index. At the height of the last property boom in late 2006 and early 2007, yields touched as low as 4.9%, the data show. Yields decline when prices rise.

Private buyers, usually without need of debt financing, are regularly willing to pay more than institutions like pension funds or insurers, said Robert Buchele, a director in central London at broker Savills. Institutions often have to measure up their returns against benchmarks. Wealthy individuals don't, making them "more comfortable with low yields, " Mr. Buchele said.

Last summer in London, Legal & General sold 97 New Bond Street for nearly GBP19 million to Wittington Investments, an investment company for a private U.K. family. The net initial yield was 2.3%.

London-based Legal & General prefers to buy buildings where value can be added through refurbishments, leasing, and other strategies before selling them to high-net-worth individuals or other large global investors, Mr. Hughes said.

But lately it hasn't always had time to do that. For example, the firm had planned to redevelop 7-10 Hanover Square, but sold it last year after receiving a GBP85.5 million offer from a wealthy European investor through Morgan Capital Partners.

To the superrich, the draw of real estate goes beyond the financial returns. Trophy assets bring bragging rights.

Wealthy individuals "think, 'I can put a picture of this asset in my office,'" Mr. Buchele at Savills said. "Sometimes that can be good enough."

Pricing for the most expensive assets inevitably trickles down throughout the market. "The smaller players are priced out of the market by the bidding frenzy" for the bigger assets, said Michael Marx, who in July will step down as chief executive at U.K. developer Development Securities PLC. Finding sites to develop in London has become "extraordinarily difficult unless you're prepared to write some pretty big checks," he said.

The appetite of the wealthy also appears to be spreading. Some of the superrich "are now looking beyond prime or trophy offices and retail space as a safe haven for their funds," Knight Frank's annual Wealth Report said.
