We've resolved to construct a simple playhouse for the kids this spring. Without a tree or any real outdoor space in the city, the playhouse will be an indoor one.That means it can't be too big or obtrusive. But the kids are asking for something more durable than the temporary cardboard "houses" we've constructed from boxes. What might be a solution for us is this playhouse we spotted over at Riemuja. It definitely fits the bill for sturdiness. And we like the fact that the framed out playhouse doesn't have walls so, even if built larger, doesn't look like something heavy in the middle of the room. Who needs walls when you've got imagination? If privacy or a fort is called for during a play session, a blanket or sheet thrown over the top will work. Simple and inspiring design that you can DIY.
