I forgot to add that the new space will have to have engineered wood floors(since they are on a slab) but the existing floors are solid (Mirage prefinished) if that makes a difference. It's also possible that the new floors will differ in not having the same microbevel as existing floors. I don't know if I should avoid a microbevel in the kitchen or match the other floors. Thanks.

Lots of homes have slabs, not joists, on the ground floor, so the joist rule might not apply to everyone. I've read so many conflicting things on this ... run in the longest direction of the room, run in the direction that the light flows in the windows, run it straight ahead as you walk in the entryway, run it so that it is lengthwise in the hallway, run it so it's widthwise in the hallway ... GAH! In my own house, if I follow one "rule" I break another one. It's maddening trying to figure out how to orient the flooring.

You have left out one very important piece of information: from where does the natural light come? Maui Mist will be perfect if the light is coming from the West. eSpresso cabinets: bright white ceiling: red oak floor: All Benjamin Moore colors South light: Grant Beige West light: Valley Forge Tan North light: Goldtone East light: Spring Meadow There are many other colors which will shine with the natural light; these are just suggestions.

Floating floors have 'length' maximums and 'width' maximums. That means t-moldings will need to be used at some point. Usually those points are in doorways. They can also be found at 'pinch points' like at the end of a narrow hallway BEFORE it enters into a larger space (like a great room attached to a kitchen). Please read your installation instruction of the product you have chosen. It will tell you the maximum runs (length and width) of your flooring. Some are as little as 30 linear feet (lengthwise) and others are as much as 50 linear feet (lengthwise). Go ahead and measure the entire length of your townhouse (front to back and side to side). You will get a VERY GOOD idea as to whether or not you are allowed (by the manufacturer) to install a continuous floor (no t-moldings). In general floating floors do NOT like to be installed AROUND a centre pillar like yours (in a doughnut shape with the centre being taken up by the kitchen). It is usually a VERY BAD idea to have a countinuous floating floor (everything connected to each other) in a circle like that. Only glue down or permanent floors get to do that sort of stuff (like porcelain tiles or glue down hardwoods). Be VERY AWARE of the limitations of YOUR HOME and YOUR FLOORING CHOICE.
