St James's Park tube station

Queen Anne's Mansions was a block of flats in Petty France, Westminster, London, at grid reference TQ296795. In 1873, Henry Alers Hankey acquired a site between St James's Park and St James's Park Underground station. Acting as his own architect, and employing his own labour, he proceeded to erect the first stage of the block. At twelve stories, later increased to fourteen, it was the loftiest residential building in Britain. The Court Circular for January 1897 describes it as "a stupendous pile which, for solidity, comfort and general convenience, sets all rivals at defiance, although twenty years have elapsed and imitations have been legion."

St. Ermin's Hotel is a four-star central London hotel adjacent to St James's Park Underground station, close to Westminster Abbey, Buckingham Palace, and the Houses of Parliament. The Grade II-listed late Victorian building, built as one of the early mansion blocks in the capital, is thought to be named after an ancient monastery reputed to have occupied the site pre-10th century. Converted to a hotel in 1896–99, it became during the 1930s, through the Second World War and beyond, a meeting place of the British intelligence services, notably the birthplace of the Special Operations Executive (SOE), and where notorious Cambridge Five double agents Philby and MacLean met their Russian handlers. St Ermin's is now part of Marriott Hotels' Autograph Collection. The hotel is owned by the family of Tei-Fu Chen, founder of Sunrider International.

The Asticus Building is an architecturally notable building at 21 Palmer Street in the City of Westminster, London.The building was designed by architects Lifschutz Davidson Sandilands with a cylindrical shape on a concrete frame in order to maximise light due to the proximity of nearby buildings. The nearby buildings, rising to up to seven storeys, made the site so difficult that it had remained undeveloped for 25 years despite its prime location. A "blister" structure at the rear in a sheltered corner was used to house core services in order to maximise usable space and avoid an awkward floor layout. The building was completed in 2006.Tenants include The Work Foundation. Outside the entrance is Tim Morgan's steel and glass sculpture Cypher (2004), one of three of that work.In 2016 it was purchased by Axa Investment Managers for £80m.
