Hiya! Sorry, had visitors this weekend so couldn't get on to post. We live in nr1 just off Ipswich road (on the right hand side as you head into town) and we love it. Just moved here recently and town is walkable in 20mins but easy to get to the main roads out of Norwich too.
We did live right in the golden triangle for a while (renting) and whilst the location is amazing, with shops and bars nearby, it's VERY studenty. A few friends have actually bought and then moved away due to problems with student properties next door/nearby, and parking is often an issue too with nearly all on street parking in narrow roads. Apparently you want to avoid too close to Dereham road side of the area.
We looked north of the city and you do get a lot more for your money; we liked a place on st Clements hill, but the area was unknown to us and just didn't have the feel we like. Also our friends are all around here, so we didn't go for that area. But walkable to town from most parts of it (uphill on return!) and good parks and schools nearby (for the future!).
We've also lived in Thorpe st Andrew, East of the city, and it's a lot quieter with a more suburban feel and wasn't really for us.
Friends live in hellesdon, but again it's not really us and feels quite suburban. Traffic can be an issue in Norwich, so think about where you'll be working and what commute you might have. I'd say a major disadvantage of living outside the city would be getting into it on a daily basis if you have to!
Roads around here seem nice (e.g. Trafford rd, grove walk, lyndhurst rd, hall rd) and friends live off city road in a cul de sac which is nice. A lot will depend on your budget though - a 2 bed terrace in the golden triangle will set you back at least £180k while round here houses are more over the £200k mark...
Hope that helps! And good luck :)
