Rabbit playhouse

Hello everyone! At the moment I have 2 rabbits and I am about to get a third.. I have a hutch at the moment but would love to give them more space. If anyone could give me any ideas on playhouses or send me there pics of them it would be great! Also could people let me know where they got there playhouses from I would be very grateful! Thank you in advance!

I'm currently spending ages renovating a secondhand 4x4 wendy house; no pics yet but it's a challenge!

There are some very nice playhouse/shed examples here: http://forums.rabbitrehome.org.uk/showthread.php?311878-Outdoor-Housing
