This house in my neighbourhood is my kids' favourite. They call it the "log house" because of the little red fence. Whenever we walk by, it's almost impossible to keep them from running around in it - sometimes I don't even try because it seems as if it was designed with kids in mind. Little miniature fences and benches to perch on, pathways to follow, birdhouses and other decorations to check out, what more could you ask for? Way more fun and interesting than the ubiquitous lawn.
I personally love the pathways made of recycled concrete and stepping stones.
