As of August 2015, good brands of children's playhouses are Little Tykes, Step 2 and KidKraft. Each of these brands has an average rating of at least 4.5 stars out of five on Amazon.com, Wayfair.com and Walmart.com.
Amazon.com reviews of the Little Tikes Cape Cottage say that it is of high quality, well-designed and easy to assemble. On Wayfair's website, reviewers note that the open design of Step 2's Neat & Tidy Cottage Playhouse prevents the structure from becoming too hot. It has multiple features, including a sink, phone, door, doorbell and built-in stools. Positive comments on Walmart.com mention that the KidKraft Outdoor Playhouse requires minimal tools for assembly and is large enough for adults to access as well.
