Urban Landscape What is the name of wood used for the deck? And what material is the fireplace?

Anne DeCocco Anyplace that sells fireplaces will sell this material, including stone yards.

I concur with Anne, your local fireplace expert should be able to help. Find one at the National Fireplace Institute website: nficertified.org.

If you're planning to uses gas (which is easier) there are some prefab shortcuts you can use, like this: http://www.firegearusa.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=115&category_id=29&option=com_virtuemart&Itemid=1

If you're planning to burn wood, you need something pretty serious like the custom concrete fabrication above. Also if you're burning wood, check with your local jurisdiction about what is legal in your community. In many areas you may not enjoy a wood fire without a sparkscreen to protect surrounding combustibles, and in some places you may need to be at least ten feet from combustible materials (like a wood deck) or have to comply with other code requirements.

If you decide to "go gas", find a reputable NFI certified gas hearth professional to help you with it. Check here: http://nficertified.org/pages_consumers/consumers-1.html
In amateur hands, gas can be much more dangerous than wood, but handled professionally, it is both safer and cleaner.
