Hi @2019mum
We live in High Wycombe. DH comes from Marlow and much prefers it (which is a good thing as we'd be in a tiny terrace up there!). I lived here as a kid and teenager, moved into London for a few years then came back.
Pros about HW:
Good schools, but you need to be in the right catchment so look around before you buy. There are schools Ofsted rated 'good' which locals avoid for a variety of reasons. Downley is probably the best area for primary state schools.
Town has everything you could need. I think the centre is miles better than it was 10 years ago. Has all the usual identikit high street stuff (Next, M&S, Pret, Starbucks) but also some cool independent places popping up (amazing vegan food truck, a WWII themed cafe, a local brewery bar...etc). It depends where you're coming from but I used to live in Bloomsbury in London and actually prefer Wycombe.
I feel really safe here - but I live on an exceptional street. It really can vary street to street. Where we currently are we have neighbourhood watch, street parties, a book club, and I love my neighbours. There's a road two streets away that I wouldn't live on if you paid me. There are loads of lovely streets but it's hard to tell which is which unless you speak to a local. For instance there are some horrid streets in Bowerdean/Totteridge and then some lovely ones a stones throw away like Rectory Avenue and Pretoria Road.
Beautiful parks - The Rye and Hughenden park are beautifully maintained. Easy access to the Chilterns and surrounding countryside.
Cons:
I do worry about green space - for instance, the Abbey Barn development (not far from Daws Hill) was completely gutting for local people. They're building on what used to be a beautiful bit of land and the powers that be seem set on letting developers destroy every bit of green belt and SSSI there is.
Centre isn't as nice as some of the villages, or smaller towns like Marlow, but IMO that comes hand in hand with having a larger town. Both sets of our parents live in Marlow and come to Wycombe to shop as their Waitrose and Sainsburys are miniscule and their high street is better for lunch/gift shopping than getting what you need.
Traffic is a nightmare. Most days I leave the house by 7 so I'm OK, but it does get absolutely gridlocked at peak time so I imagine a nightmare for people who drive kids to school or work in the centre of Wycombe.
We are happy here but only live here as DH won't ever drive due to eyesight issues so need to be near station with access to London and midlands. If this were not the case we would be in Flackwell Heath, Downley, or further afield in Tylers Green, Great Missenden. If you're looking at the houses I think you are, I think you can also get a much better street/area/house for your money if you're willing to buy an older house and not a new build.
