how to build a diy fireplace mantel

Nice crown molding above, but not so nice fireplace mantel below.

Big is no substitute for a lack of the proper details that make up all the parts of a fireplace surround.

This one is missing capitals and base on the fluted pilasters.

In addition, the frieze is disproportionately tall and the crown molding is too weak for the size of the mantel top.

But this is the kind of thing a builder asks the trim carpenter to install — even in expensive homes like this one — only because it can be built in an hour or less (read, cheap).

But after I installed a large, three-piece crown molding in this great room, the home owners were ready and willing to install a new fireplace surround.  Take a look at what I came up with.

I built this whole thing with simple materials. You can build one too, it’s not hard at all.

Think of all the ornate appliques you could apply to the frieze and capitals!

The fireplace mantel I built with lugged architrave overmantel took much longer than an hour, but it’s what belongs in a nice great room like this.

These two patterns may look complicated to build, but I assure you that they are not.

Just like most of my designs it’s a matter of building a core of mdf flat-stock to wrap simple moldings around.

You can see how I built the overmantel here at How to Make OVERMANTEL-100 for About $87.39: Part 1.

You’re in luck if you’d like to learn step by step how I built them.

I have the entire installation sequence for this fireplace mantel that I’ll post in the near future.  If you want to stay up to date with all our new tutorials, then you can subscribe to The Joy of Moldings via email or have new posts sent to your RSS reader.
