Good or bad to buy a playhouse for toddler?

If you have the space, sure why not? Personally, I would not have a playhouse in an apartment -- clutters up the space, collecting dust which could just add to the "pollution" at home. To me, playhouses are awesome to have in the backyard or garden -- which most of us living in Singapore do not have. Why not make one of those indoor forts from blankets, chairs and cushions. You can make them whenever the kids want to play in one and then diassemble it when they are done.
