Family (52) seeking house in Kingston upon Thames

Hi, we are looking for a new long-term home. My son is 11 yrs old and home schooled, he is neurodiverse and requires an emotional support dog to help develop his independence and confidence. However my current landlord of 11 years still refuses to allow us to have a small/med dog. We are looking for a bit more space too, so we would need a garden, garage, bath and 3 bedrooms (as granny helps out a few days a week for me to work). My son's father is happy to be guarantor. We can live anywhere in Kingston-upon-Thames borough, as long as its near a bus stop. Thanks
