Old Multi-Wythe Brick House 1

[kmart30]

Looked at a possible project of an addition to an old 2 story multi-Wythe hollow brick home with a wood floor and roof. It’s a simple rectangle structure with a hip roof. Architect wants to demo one side of the house and attach a small 2 story addition to it. The addition will be wood with conventional framing and an overframed roof to tie into the existing. There will be a new wood wall in the same location as the old exterior brick wall with some openings that extend into the new addition (same width as house)

There is an exception in the code for additions to single family homes regarding the existing LFRS but just not sure on how to approach this one. Design the new exterior wood wall to take the shear from the old brick wall? Come up with some new steel or CMU in the location of the old brick wall to keep stability? Both? Stop trying to create problems out of 100-year-old structures???

masonrygeek,

Thanks for the excellent "tile 101" for me Is the clay tile the same as terra cotta tile? Is it considered a structural material, facing material, or both? Especially in OP's case - laying horizontally.

masonrygeek - don't forget about Thru-Wall from Belden and similar products from other manufacturers. Falls somewhere between clay brick, clay tile, and CMU.

oh, and terra cotta (thanks retired13) - also a fired clay product, but with a very fine grind; often glazed and used as ornamental/decorative cladding on a building; older versions had open cells similar to clay tile, but since it was decorative with shapes the openings varied in size; some people call "clay tile" "terra cotta tile", but that's not really appropriate.

Thanks pham - Belden makes more of a hollow clay brick (ASTM C652). Interstate Brick (UT), Glen-Gery (PA) and a couple of others make this type of unit as well.
