Studios are often conversions in old Victorian houses, with a large and characterful main room.
The thing is, it’s not great to sleep and spend all your time in the same room, especially when other people come round, as others have mentioned.
Everyone upthread points out mortgage difficulties, re-sale difficulties with Studios. A 1 bed is nicer to live in and a better investment in most cases.
Of course if you’re looking at a horrible 1 bed, the studio will look nice. There are good and bad studios and good and bad 1 beds. Perhaps given the 1 bed is only £7k more than studio, it’s not a very nice 1-bed.
There are always more 1 beds available. You will have to consider the price range for 1 beds and de ide if you can afford a decent one. Pushing yourself for a 1 bed is a good idea if you can. However, I’d t buy something g horrible just because it has a bedroom. Presumably it doesn’t have to be this particular 1 bed…you can keep looking.
And advice on this thread has been unanimous which is rare.
Of course if your budget is studio flat budget, then that is what you should get. Lots of people start off with one, and whilst there are downsides, they can be a good start.
