In a past interview with Sky News, the Countess explained: "We're a lot more fortunate because we live so close to the Queen, so when she spends a lot of time at Windsor on the weekends, our children are more fortunate because they can go over and have tea with her on a regular basis."
Edward and Sophie moved into the property following their royal wedding in 1999, and they clearly plan to stay since The Telegraph reported that the couple extended the lease from The Crown Estate for another 150 years.
The Grade II-listed building is set within 51 acres of land and is rumoured to have a whopping 120 rooms after it was demolished and rebuilt in 1879 – in comparison, Prince William and Kate Middleton's Kensington home has 20 rooms. So no wonder it is estimated to be worth £30million if it got listed on the open market. Take a look around…
The couple allowed press into their home recently, revealing their stunning light-drenched conservatory with views of their lawns. It has terracotta brick walls, a dining table, a barbeque and house plants.

The Countess invited BBC's Naga Munchetty inside one room of the lavish royal residence decorated with green striped upholstered chairs and a matching green carpet. It also features a gold-edged mirror above a stunning marble fireplace, multiple vintage sideboards and luxury artwork.
Prince Edward inadvertently shared a look at his home office as he officially opened the NHS Nightingale Hospital in Bristol. It features a wall-to-ceiling wooden bookshelf, with several trinkets and framed photos, and is designed with carved wooden walls.
We may have got a look inside the grandest room in the family home when Sophie released another video of her work. It features carved wooden walls with enormous double doors and brass handles, as well as two glass side tables with brass legs. On one table, there is a small pot of cream orchids, a selection of ornaments, a photograph in a silver frame, and a desk lamp with a white shade, while the other seems to hold a trinket box.

Sophie revealed more of the kitchen than ever before as she filmed herself baking scones. It showed sage green walls, chic white cupboards and coordinating white marble worktops.
It seems Sophie and Edward also have a second kitchen. We got a peek inside when the Countess joined a video call with Thames Valley Air Ambulance. The mother-of-two sat in a corner of the space, alongside open shelving with a telephone and selection of vases and ornaments on display. It appears to have a classic dark navy scheme, with glass-fronted cabinets behind the Countess showing some of their fine china including an assortment of teapots and teacups and saucers on glass shelving.
The grounds are equally as impressive, with a private lake and several stables set within 51 acres.
We got a look at the outside of the property when Edward, Sophie and their children joined the #ClapForOurCarers at their home. They could be seen standing outside a set of glass doors, with a climbing plant growing up the brick wall in the background.
