Grimm's Giant Building Blocks


These large building blocks are also ideal for playing outside since structures can be stable on uneven surfaces as well. The arches are great for building different houses and play worlds. 19 pieces. Materials: lime wood, non-toxic plant based oil finish. Size: H = 7cm, L = 7-21cm.

Recommended Age 12+ months

In combination with Grimm's classic building materials like the Wooden Marbles, the small and large stepped pyramid, the Building Boards (new item 2018) or the Building Set Cornerstones (new Item 2018), the Giant Building Blocks, reveal their true greatness. With their aid, the most diverse marble runs can arise.

We have added three examples (see photos) of how to built your own marble run made of Grimm's Wooden Toys. It can take some experimenting until the step height matches the ball size and the optimal distance between the cornerstones is found. Tricky building and construction for adults and playing fun even for the little ones. If everyone works together, great things can happen.

(1) Marble Run Staircase: In combination with the Large Stepped Pyramid, the Giant Building Blocks and the Building Set Cornerstones this marble run staircase was created for Wooden Balls.⠀

(2) Marble Run Bridge: This daring bridge construction for Small Wooden Marbles is a combination of the Pastel Buidling Boards the Small Stepped Pyramid, the Building Blocks - Tree Slices, the Giant Building Blocks and the Building Set Cornerstones.

(3) Marble Run Spiral: In combination with the Large Stepped Pyramid, the Giant Building Blocks and the Building Set Cornerstones was created for Wooden Marbles.

We can't wait to see all the inventors and architects out there!

These giant blocks certainly live up to their name! They are perfect for learner builders and older kids alike. The quality and feel of the wood is second to none, for sure one of our favourite purchases from Oskars!

Amazing product

Brought for our sons 1st birthday. This is our first block set and I absolutely love it nice and big for them to grasp and the natural wood looks lovely.

Best blocks

I was hesitant to buy these blocks because there are not many for the price but i am so glad I did. We use them with all our other grimms items to make towers, ball runs and houses. Both my 9 month old and 2.5yr old loves them.

Beautiful toy!!!

My son loves it!

Best blocks!

Recently purchased this set for my 18 month old. He was getting frustrated with smaller blocks falling over/being too difficult to stack straight. These blocks are fantastic and a favourite item in our house now - even my hubby and I get excited to play with them daily with our son. He can easily stack them high, builds houses for his stuffed animals etc. They can easily be incorporated into other games. They're large and grippy, and smell amazing. Fantastic quality. I can't recommend them highly enough!

Incredible quality

We just love how gorgeous the grains are on these big grippy blocks. And they really are big and grippy! Perfect for the youngest to build because they grip so well onto each other.


These are just amazing. Great size for 15mo so grippy and just beautiful


Absolutely in love with this set. The natural look is so beautiful with the wood grain and it goes well with other coloured blocks we have at home. Little one loves rolling her cars under the bridge and could do it all morning!

Beautiful set

So looking forward to gifting these to my son at Christmas. We have tried a non Grimm’s set with smaller pieces and my son has found them very hard to stack and manipulate. These are such a great size for little hands.


These are our first set of Grimm's building blocks after much research (and anticipation at restock!) and they surpass all expectations. They are splendid in size and quality, stack brilliantly, and a fun addition that seamlessly fits in to other toys and play scenarios for everyone. They really are something special and different to what is out there, and definitely a keepsake item.
