It is wall-to-wall subs today! Everyone from the tile guy to the fireplace guy to the painter to the granite-pillar guy - that would be Roger - are at the Concord Cottage. Kevin checks out Roger's latest project: installing granite bollards in front of the barn door to prevent vehicles from accidentally backing into the barn, while also adding lots of old-time character. In the front hall, tile contractor Joe Ferrante is prepping the radiant deck for tile, first with thinset, then with cement board. In the living room, chimney specialist Mark Schaub shows Kevin the new remote-controlled gas fireplace that can be vented up or straight out, via an exterior wall, and installs in about a hour. At Boston's Design Center, Kevin meets interior designers Tricia McDonagh and Charles Spada to see the antiques they've selected, and are still considering, for the cottage. Back at the site, Kevin lends Norm a hand installing the sliding windows over the kitchen sink.
