- Changing from your existing masonry fireplace to the linear gas fireplace in the photo you posted a link to would likely be fairly expensive, as it would require removing/modifying the masonry of your existing fireplace, but there are other approaches you might consider. One of the keys to modern is minimalism. You might try keeping the appearance as uncluttered as possible - perhaps by removing an existing mantel or stripping away other elements to leave only the most essential parts. If it is a wood burning fireplace, the building code requires that you leave non-combustible hearth protection in front of the fireplace, but you might be able to change the hearth material to make it more modern (pink wall with hearth flush on floor). The other thing you might consider is changing over to a modern gas burner, with glass media or stones (first photo, with black mantel). There are gas inserts that are beautiful as well last photo with stone wall), but the investment goes up when you get into a full system with firebox, surround, venting etc. If you have a photo of your current situation, we might be able to tailor our suggestions to be more helpful.

Some kind of teak wood would be best. IPE is what this looks like. Please purchase responsibility as it is harvested by clear cutting in some areas. FSC is best.

HDF is High Density Fibreboard as opposed to MDF which is medium density fibreboard. If sealed properly it can be used outdoors as panels set within hardwood frames. Better still is marine grade plywood
