By 1844, Albert had managed to modernise the royal finances and, through various economies, had sufficient capital to purchase Osborne House on the Isle of Wight as a private residence for their growing family. Over the next few years a house modelled in the style of an Italianate villa was built to the designs of Albert and Thomas Cubitt. Albert laid out the grounds, and improved the estate and farm. Albert managed and improved the other royal estates; his model farm at Windsor was admired by his biographers, and under his stewardship the revenues of the Duchy of Cornwall—the hereditary property of the Prince of Wales—steadily increased.
