My eldest boys are at the age where building blocks just don't cut it, apart from LEGO that is. They find Meccano boring and are just not interested in wooden blocks etc. That's why I think they would go daft for the 'Kids Can Build' range at B&Q. They start from £3 a kit and contain all of the materials to build set items. That includes REAL bricks and child-friendly cement.
The cheapest set that B&Q sell is the Kids Can Build A Kennel Construction Kit* for £3. This one is the only one available to buy online. Buy one today and get 10% off when you use promo code EMAIL4173 at the checkout.
Each set contains: Bricks, Mortar, Trowel, Mixing Bowl, Base & Instructions.
I might have to buy an extra set so I can have a go!
