We moved from Balham to Streatham Common/Norwood border last summer, coinciding with my son's move to secondary school in Dulwich. Our house and garden are completely different from the semi we moved from and the garden especially is far bigger. It has taken a while to get used to not having the tube nearby, but that is the only regret we have. Our road in Balham was very noisy and we are now in a very quiet spot close to Streatham Common, which is glorious. The woodland at the top, and the Rookery formal garden is amazing and great for kids. There are 2 new leisure centres being built round here - one in Streatham and one in West Norwood, state primaries and secondaries seem to be improving by the minute (check out Dunraven School's new buildings) and there are fast trains to Victoria, London Bridge, Blackfriars. It takes 25 mins for me to get to Farringdon on the Thameslink train from Streatham for work, far quicker than using the tube from Balham. We're gradually getting to know which bits of the high road are worth a visit, but to be honest, we rarely need to drive down it, as there are so many better ways to get across the area. Hope you find the right place for you.
