If you have a local B&M type place (not B&M but similar iyswim, the one nearest to me is called What!) you can get the doll house accessories there for pennies in the craft aisle so there’s no need to search for one that comes with furniture. I don’t have kids so don’t know what the best is at the moment but I know when I was a little five year old girl I had a wooden dolls house - it was sturdy and lasted years and years - when I was twelve it was passed to my niece and when she turned nine it was passed on again so I would say don’t bother to go for the trends and get a Barbie house or a LOL doll house because you pay for the money and not the quality. Failing that, maybe look at the Sylvanian Families sets as I’m sure they do cottage type sets. I think the Sylvanians are plastic (from the memory of the one I had) but the one I had was passed down to me from the eighties and is still in fantastic condition!
