As far as areas go, I would look into transport links. If you are working in the city & your husband in Richmond, Clapham Junction could indeed be a good choice. There are fast trains available to Richmond & then other trains available into central London (Waterloo) from where you can catch the Underground to wherever in the city you are located. However, there are plenty of other options besides Clapham Junction, so make sure you get familiar with public transport in and around London!
