We live in an end of terrace and our 4 neighbours have a right of way through our garden for putting wheelie bins out. We have lived here 3 years and it's not ideal, but the way the outside space is set up, we have a wrap around driveway which goes across the back of our house, then a little fence and gate into our actual garden which is over 100 foot and if you sit on the deck round the back of the garage, you are not overlooked at all. The shared access has never really been a problem but we can't really join up the inside/outside space very well as we want to keep the 'no man's land' area.
All the neighbours use the access one day a week for bins- rarely gets used at weekends etc and if it does, they don't come in our actual garden iyswim. The issue is, we are thinking of spending a lot of money on a downstairs extension- we have already done the loft so have 4.5 bedrooms.
Basically I'm worried that we won't ever get our money back as no one will want a big family house with the shared access issue. The house was 3 beds with a downstairs bathroom when we bought it. I don't know if it would bother people with younger children? Ours are 5, 10 & 13 so i don't really have to keep an eye on them outside etc. it's a really good garden space, which is why we bought the house- it was either a private postage stamp garden, or a much bigger garden with the shared access across the back of the house where the drive is. If you had to choose what would you go for and would it put you off a house????
