Well, if it were 15 years ago, I'd consider it maybe, but getting close to retirement and starting to think about eventually relocating, I don't want to do any expansion now.Assuming enough room and your local laws (zoning) allow. An edition to your home. The slab and stone over CMU,s (concrete masonry units) is not a problem. They even make stone to match color, size, style of existing. Size and other physical considerations would depend on budget.
