How do you want to travel?
If you are renting a car then sat nav is the best option - but failing that you could try the AA (Automobile Association) route planner in the link below http://www.theaa.com/route-planner/index.jsp
Alternatively you can get a train or bus link to London Victoria Station and from there either another train to Putney Station (about 4 miles) or a cab to your final destination.
