One of the things that will make a space feel larger is to have the same flooring material throughout. Shannon's kitchen and family room floors were Saltillo tile set on the slab and the living room was 2 1/4" hardwood floors set on screeds. In the picture below, we have removed the tile, the tile thin set, the wood floors, and the screeds then we scraped the old tar:

As you can see there is a big difference in the floor heights. Also, the slab was not level, so we use a leveling liquid to smooth the floors. Where the wood floors used to be, we poured new tar, set new screeds and added a moisture barrier:

Then plywood was laid on top:

In the area where the tile used to be, we used a liquid moisture barrier:

Once all was dry, we started laying the floors:

Shannon fell in love with this 5" pre-finished engineered flooring from Anderson Floors. The floors took 2 weeks to complete, aren't they pretty!
