Beautiful, 6 Bedrooms in a Private Estate

We are an English family that has owned this house for about two years. We extensively remodeled it (it took a year) so that it can now be considered new. We live in a gated community called Altos Del Pilar and is quite unique as there are only forty homes all with very large plots. Ours is over 5000 m.We all have excellent security.There is also a large club house with pool and tennis etc. Altos is located 42.5 km from the Capital and is to the North of the City near the Argentine Polo Farms and the town of Pilar. We live a very green existence with lots of beautiful trees in our neighborhood. It is very quiet and relaxing. The house is of a high standard and although it is about 700m in size it feels very cosy. Our garden is gorgeous with a large pool and an indoor Parilla (Barbecue) We have a full time maid and a gardener and Nannies are available if needed. We absolutely love it!
There are lots of good restaurants in the area and of course its only 35 mins to the Capital. Horse riding and out door activities are everywhere in this area. Argentina is a huge country with Skiing in the South and Iguassu Falls in the North and of course Tango and beef in Buenos Aires City.

*We want to move to the UK for about a year, starting approx next year for business reasons and are interested in swapping with a house in the South East,Surrey/Sussex area preferably.
