Well now a company based in the United States called Strictly Briks have solved that problem with the own range of Lego compatible base plates and special bricks which are used to build stack-able structures for storage and play.
The plates are great for children constructing buildings but they also make good higher level storage solutions, which is useful if you’ve got loads and loads of Lego and not enough bedroom space to have it all out all across your child’s bedroom.
Strictly Briks also do a range of even larger base-plates (which cann’t be stacked) but which come is a far wider colour range that those available from Lego. These are great for large scale play and we’re planning to fix a couple to Small Son’s bedroom wall to allow mini-figures to be displayed in picture form.
They also make silicone base-plates in a wide range of shapes and colours which are perfect for easy storage and for travelling, if you have small people who like their Lego to go on holiday with them!
Most of the Strictly Briks range is available for both small standard Lego and also for Duplo. It’s all very reasonably priced and available direct from www.strictlybriks.com and from retailers such as Amazon. Highly recommended 🙂
