Microsoft has five buildings at the far end of Thames Valley Park, located about three miles from Reading Town Centre. All of the buildings are connected via a ground floor walkway. TVP is the larger of their UK facilities, they have another office in Cardinal Place, near London’s Victoria Station.
Events are typically in building 2, which has a large amphitheatre seating over a hundred. There are restaurants in building 2 and 5 that serve pretty healthy and quite high end meals.
To get to the office from the Reading rail station, you can take a taxi for about £10 or the free shuttle bus to Thames Valley Park. The bus stop is just outside the station, near the passenger drop off right next to the Three Guineas free house.
Security is present — you’ll need to show your badge or sign in to drive into the property (there is plenty of guest parking) and you will absolutely need to swipe your badge to enter any of the buildings or to transfer from one to another.
