How to Build a Simple Do-It-Yourself Corner Fireplace

I had to remove an old wood stove in my house and I decided to replace it with a corner fireplace.

Our DIY Corner Fireplace

We were very happy to have found a house that was perfect for us at a reasonable price and in really good shape. The main floor was well kept and up to date with hardwood floors, new cupboards, windows, etc. All it needed was some paint to make it ours.

The basement was a different story, but we could see the many possibilities. It was a good size with a bar, storage, workshop, laundry area, spare bedroom, washroom, and a wood stove. The problem was the décor was stuck in the '70s, and we were not quite sure where to start. Well, the insurance company made that decision easy for us.

The old wood stove had to be removed as it did not have a certification sticker. Believe me, I was glad to be forced to get rid of it as quickly as possible. As you can see from the picture below, it looked like it belonged in a cottage rather than a home. Our first task was to get the old, extremely heavy wood stove up the stairs and out of the house. That required a couple of strong men. I was no help there.

Now, what do we do with the ugly empty brick corner of our basement? That was more my department.

This is the "before" shot. Yikes, where to begin.

Cost and Time

This whole project only cost $300 and took one weekend. We really didn't have a clue initially what to do but once we got a plan formed in our head the rest went very smoothly.

After much deliberation, we decided not to spend thousands of dollars on a gas fireplace but to install an electric fireplace insert that was on sale. The basement was already heated so we felt that an electric fireplace would provide sufficient heat to take the chill off and add to the ambiance of the room.

Before we began, I was scouring the internet for ideas on corner fireplaces, and many were beyond the simple scope that we were looking for. Although your project would have its own unique qualities, I hope ours helps with some ideas, even if it is just from the before and after pictures.

How to Build a Corner Fireplace

Initially, we were not sure whether to remove the bricks, as you can see from the picture above. We decided it would be easier just to paint them out and keep the whole project simple and monochromatic for a modern feel, which this basement needed badly.

After painting the bricks that we thought would remain exposed, we needed to determine how far out we wanted the fireplace to extend. We debated on having some bricks remain on each side, and I am so glad we squashed that idea. Bringing the triangle out to cover the bricks was in keeping with the modern feel.

Step 1: Building the corner frame.

Tools and Supplies Used for This Project

  • Electric screwdriver
  • Miter saw
  • Concrete anchors, wood screws
  • 6 2x4s
  • 2 2x2s
  • 1 sheet of drywall
  • Ready-made drywall compound
  • 1 sheet of pressed wood or plywood
  • 1 gallon of paint (I used the Behr Premium Plus Ultra, Paint and Primer in One in an eggshell finish)
  • Molding or fireplace framing

Choosing Your Materials

Now you would need to adjust this list according to the finish you want. For example, we simply wanted a flat front surface to paint, so sheetrock was a good choice for this project. If you want to add rock or tile to the front, it would be better to choose something more durable like plywood.

Also, on the top, we cut back on expenses and got pressed wood for $7.00 rather than plywood for $30.00. We gave it a coat of ready-made drywall compound to fill in the cracks, thus giving us a nice smooth finish and strong support for a flat-screen TV later.

At the base, attach measured and mitered 2x4s to the wall and front forming a triangle. Repeat the triangle at the desired height. We felt 2x2s were sufficient supports between the triangles on the wall but used 2x4 supports in the ends and front.


Building a Support for the Insert

Next, we assembled a simple support for the insert, shown in the above picture. Then we completed the finish with drywall for the front and pressed wood with ready-made drywall compound on top as noted earlier.

As you can see in the picture below, there were small bricks remaining on the front of the concrete base. We decided to remove them and simply paint out the roughness of the concrete to give it a rock feel that blends in. Finally, the rest was painted in the same gray color for a completely updated cozy corner.


Finishing the Project

As you saw in the first picture, there was a wood stovepipe extending into the wall from the outside. After insulating the pipe, the clock was our temporary solution which we think works well.

We were quite proud of the outcome of this little project. It was done on a small budget but made a dramatic improvement. This project could be altered in so many ways to suit a variety of decors. Just imagine the possibilities with available funds and creativity.

I can't wait now to bring the rest of the basement into the same century.

Please keep in mind we are not professionals. I am just sharing our little home improvement project idea that was great for our needs. Good luck and have fun with yours.

Great job I have a corner in my great room that would look great in!

I did the same thing. But rather than making a hole for the insert, I used a wall mounted gel fuel fireplace and hung it on the front. It fits so tight against the surround you can't really tell it's not inserted.

I did the same job myself installing a wood burning fireplace. This kind of job seems to be easy, but in fact to install anything at all requires much work and thinking over :) Great hub!

Thanks scaffolding. It is really doable for anybody. We took our time giving it some thought and came up with this very inexpensive plan to work with what was already there. I love finding simple solutions that show big improvements.

The step by step, which is even shown in the pictures, is amazing. You just make this sound really doable.

Yes, it did make the room feel bigger and we now enjoy that corner much more. Thanks heart4theword for checking it out and commenting.

Your fireplace looks great! Very Simple, yet Artsy:) Probably made the room seem a little bigger, using a lighter color, for your corner. Glad I checked it out:)

Thanks AnythingArtzy. Doesn't it just feel great when a project actually turns out as you imagine or better. Of course anything would have been better than what was there before. lol

I'm a big fan of do it yourself projects. I have made over countless things in my own home and I commend anybody for taking on those kinds of projects . they can be quite overwhekming but this is just beautiful. GREAT JOB. I Wish I had a place for a fireplace now. lol
