He is buying a Suffolk estate for £45m — a record price for a British country home. Maktoum, 59, has snapped up
Dalham Hall, a grade II listed property near Newmarket once owned by Cecil Rhodes, the mining magnate and colonial adventurer. It comes with 3,300 acres of farmland, parkland and woods, as well as 39 houses and cottages. In an unusual twist, Charles Philipps, one of the trustees of the Dalham Hall estate, and his wife will continue to live in the early 18th-century mansion. Other Philipps family members who live on the land will also remain.
The Dalham Hall estate, one of the most impressive in East Anglia, is centred on a mansion built for Simon Patrick, the Bishop of Ely, in 1705. “It’s not really pretty, but a substantial and elegant family home with a very distinctive location,” said one person familiar with the property.
Maktoum already owns the neighbouring Dalham Hall stud, a 3,000-acre site from which he runs his global bloodstock empire and where he spends part of his time. By combining the estate with the stud, Maktoum will become one of Britain’s biggest foreign-born landowners.
It is thought that the sheikh’s latest purchase, bought through his Darley Stud Management company, is mainly an investment, although he and his friends may well choose to make use of the estate’s shooting facilities.

I'll be there in this area in one week. I'm not sure that it will be possible to walk around there and near that villa but it's cool to realise that you're living close to Maktoums
