The family's expanding portfolio now totals seven homes, including four in central London. The latest addition is a four-storey, Grade II-listed town house just a few streets away from the Blairs' £3.7 million Connaught Square mansion. Mrs Blair and the couple's son Euan, 26, secured the three-bedroom Edwardian house in Marylebone for £1.3 million. Land Registry documents revealed they used a mortgage to buy the property together in April. It was not clear whether the mortgage was taken out by Mrs Blair or her son, who reportedly received a six-figure bonus from investment bank Morgan Stanley this year. His spacious new town house boasts three bedrooms, two bathrooms, a bespoke designer kitchen, study, dining room and garden.
Friends said Euan had 'outgrown' the two-bedroom basement flat he bought two years ago in Islington, North London. He has accepted a £500,000 offer for the flat but is staying there while builders refurbish his new home. The Blairs' architect Simon Templeton has already submitted plans to install a skylight as well as a gate in the railings outside the listed property. Euan's new home could soon rival his younger brother Nicky's nearby mews house, dubbed the 'ultimate lads's pad'. Nicky, 24, bought the £1.13 million property with his mother last year, mortgage-free. Meanwhile the Blairs's daughter Kathryn, 22, is studying law in Strasbourg, where she has an Erasmus scholarship.
