We visited Butser Ancient Farm this afternoon after spending the morning in Portsmouth. It's well signed location just off the A3 is very convenient.
The site comprises a visitor centre (gift shop), iron age village (with a main roundhouse and half a dozen or so smaller dwellings), and a Roman villa reconstruction complete with working hypocaust. There was also a Neolithic section in preparation, and we were told planning permission has been granted for a long house.
Staff are very friendly and knowledgeable about the history behind the exhibits, making this a very enjoyable visit. The only very small negative (and it is very small as I fully appreciate the need to fund the project) was cost. While relatively modest compared to many attractions, I paid £23.00 for two adults and three children (family ticket plus additional child ticket), while the visit time was circa two hours (this being sufficient to view everything). Not a major problem for my first visit, but something that is likely to stop me coming back for a second visit (which I would be otherwise open to do, especially as the exhibits are developed).
That said, if you haven't been and are on route to or from Portsmouth then give it a try - you won't be disappointed !
