Hi A.
My almost 4 year old son loves dollhouses. It is more the fascination with roll playing than anything else. I bought him a small wooden kitchen with wooden vegetables to cut and pots and pans first and more recently a wooden gnome house. My son saw one at a street fair about 6 months ago and since seeing it hasn't stopped playing with it. It was not very expensive - here is the website http://www.aewoodentoys.com/. I actually would have bought him one like you are talking about but he found this one. It came with 4 peg gnomes, a swing, a hammock, a log bed and a log couch - and that seems to be just enough.
The things that keep my son the happiest and are just now really building his imagination are his kitchen, and house. I say - go for it, but keep it simple!
