Great Portland Estates has appointed brokers to sell 30 Broadwick St. for more than £190M, as the company continues to tap into demand for prime assets.

A marketing brochure for the building indicates a price of £190M would represent a net initial yield of 4% and a capital value of £2K/SF. CBRE and Colliers are advising on the sale.

If a sale goes through, Great Portland Estates will have sold more than £900M of West End assets in the past 12 months, as overseas investors continue to pay high prices for fully leased office and retail schemes.

In February 2016 it sold Rathbone Square, where tenants include Facebook, to Deka for £435M. In November last year it sold 73/89 Oxford St. to Norges Bank Investment Management for £277M.

It has been cautious about reinvesting the money raised, and gave some of the proceeds from the sale of Rathbone Square back to shareholders in the form of a special dividend.

The sale of the 94K SF 30 Broadwick would be among the 10 largest deals in the West End this year. Rathbone Square was the largest, according to data from Real Capital Analytics.

Great Portland Estates completed the development of 30 Broadwick St. earlier this year and has achieved the highest ever rents in Soho, at more than £100/SF. In total the building has a passing rent of £8.1M and a weighted average unexpired lease term of 11 years.

Great Portland declined to comment.
