Building Tall Trees with Cylinders

I was originally going to talk about building cylindrical columns. Then I realized that the only things that I’ve built with this technique are trees. Tree building is a very important topic in MOCing. There are probably as many different ways to build trees as there are types of trees. Lego Arboretum is a very good resource for that. But today I’ll focus on one cylinder building technique and using it to build trees, building tall trees.

This technique involves rotating brick with studs on all sides at 45° angle to form octagons.


This is structure is most sturdy when you have at least two studs connection on all 8 plates. To achieve this, it has to be at least 8 studs tall. And 8 studs tall segments are a decent size to work with. We can expand on this to form larger cylinders. Such as these.


These also needs to be 8 studs tall to be sturdy. If we go even wider, it’ll look to octagonal. So we need to increase to 12-sides.


By rotating the center structure 30° and 60°, we can form a 12-sided cylinder. The only drawback is to achieve 2-stud-connection on all sides, we need it to be at least 14 studs tall. (in my example it’s 16 studs tall) When the structure gets tall, the base gets too weak with only one stud connection. So we need to expand the base with headlight bricks.


Building Tall Trees

To build a tall tree such as pine tree or redwood, first build the tall and straight tree trunk by stacking the cylinders that we’ve talked about already. Depending on the size of the tree that you are building, you can adjust the size of cylinders that you put in.


Then add branches to the bare trunk. There are many different ways to do this. Depends on what kind of tree you are building, you can customize it to you need. Here is one way.


Alternate between different patterns to achieve the most natural look. In the end you should get something like this.
