DIY Projects: 15 Ideas For Using Cinder Blocks

Cinder blocks are actually CMUs (an acronym for concrete masonry unit) i.e. large, rectangular bricks which are used in construction, but have a lot of other uses.

We’ll explore 15 smart ideas for using cinder blocks for your homestead.

Why cinder blocks you may be wondering? Well, because they’re readily available at any hardware store or construction site, you can get them for basically nothing if you scrap or recycle them, they’re relatively lightweight, tough, and they require next to nothing in terms of maintenance.

As you can see, they’re perfect for building all sorts of things (affordable, utilitarian pieces mostly) at dirt cheap prices when compared with what you can buy from a hardware store.

1. Build a Block Fire Pit Using Cinder Blocks

First you should check out the laws and regulations in your county regarding building fire pits. Sometimes you’ll need a permit and may also have to pay a relatively small fee for building it.

After that, you’ll need to choose the best spot for your cinder block fire pit. You’ll want it to be far enough away from your house, plants, firewood and anything else that it may ignite accidentally. Ideally, your block fire pit should be in the proximity of a water hose in case of fire emergencies.

After you’ve found the “sweet spot”, all you’ll need are 24 fire-resistant cinder block caps, 2 bags of lava rock and a bag of mortar, with an estimated building cost of under $50. Here’s how it should look like:

 2. Use Cinder Blocks for Root Cellar Shelving

Yes, you can use cinder blocks for building furniture in a way that doesn’t look terrible!

You won’t even need to glue, nail or drill them so they make for an awesome raw material for building shelves in your root cellar. The designs, patterns and size options for building shelves out of cinder blocks are endless.

Basically you can put cinder blocks to good use in your cellar for storing your food, gear and whatever else you’d like in whatever style you choose.  This is an example of what a true prepper’s cellar might look like.

3. Build an Outdoor Cinder Block Bench

Here is yet another great idea for building outdoor furniture using cinder blocks. The main advantage of this DIY project is that it can be done in half an hour with almost no tools required.

The cinder block bench is weatherproof, tough as nails and it looks great! You can decorate it even further; the only limit is your imagination.

The hardest part of this DIY project is to load and unload the cinder blocks; the rest is a piece of cake.

You may want to add some paint and cushions and voila, for under $30 you can have your own customized outdoor cinder block bench, which comes handy for any occasion.

Just take a look at the picture and figure it out for yourself. With just a few cinder blocks you can build yourself a cool fireplace at next-to-nothing costs, saving you a great deal of money and adding a practical and attractive element to your garden or outdoor space.

The best thing about this project is that you can always dismantle it, put it in the back of your truck and relocate it wherever you need it. Since there’s no mortar, glue, nails or anything like that involved in its construction, the cinder block fireplace can be easily moved around with minimal effort.

Or, you can build it in your favorite place and forget about it, as it’s weather proof and it doesn’t require maintenance at all.

9. DIY Your Own Ground Fire Pit Using Cinder Blocks

If you take a peek at this pic, you’ll probably think about weird stuff like human sacrifice. Actually, it’s a ground fire pit made from cinder blocks and used for cooking, getting warm or roasting marshmallows on a nice night. It also looks pretty cool, but before starting you may want to check out your local building codes to see if that’s kosher in your area.

Using cinder blocks for this endeavor will require minimal effort, little money and next to zero skills. It’s an awesome project to do with your kids, as it needs only minimal supervision and makes for lots of fun.

{adinserter usf}You can start with a temporary ground fire pit and you can convert it later into a “permanent” (as in mortared) affair if you decide you like the concept and location. Don’t build it near flammable structures like garages, sheds, overhanging trees or your home.

Also, you can build this baby directly on the ground, with the cinder blocks corralling the flame, but I would advise you to remove 5-10 inches (as pictured) of soil and place the first row of cinder blocks below the ground, thus making for greater stability and safety for your fire circle.
