There are a lot of us looking for a decent wooden playhouse that doesn't break the bank, and I think this one looks fab. The Billy-Oh Junior Playhouse With Picket Fence was just short of £150, and has now been reduced to £134.99, and has free delivery thrown in as well!
I know that Asda have some similar looking ones in some stores for £125, but as well as being bigger this one has the extra of the little fence to make a miniature front garden for the playhouse. For an extra £10 that extra room inside definitely seems worth it (that's from someone who was made to sit inside the display one in Asda). It's a 4 ft x 4 ft playhouse, with styrene windows, and a stable door.
Some of the plastic playhouses with no floor are the same price as this wooden one, and this also comes with a 10 year anti-rot guarantee, so it should last way past the time your children grow too old for it.
This playhouse is an online exclusive so you cannot collect in store, but home delivery is thrown in for free, saving another £8.95.
