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.

Oops, sorry - I should have mentioned that we have a slab foundation. Here's the link: www.truehardwoods.com If you call and talk to Justin (it's a family-owned and run business), tell him hello from the customer that bought 70 cartons of Castle Rock Birch shipped to Texas! We're installing it ourselves, so we decided to do floating. He recommended we use the Silencer underlayment.

Thanks. I know that was a little confusing. I'd post a photo of the layout but the photos are on a computer that is inaccessible right now. Anyway, it sounds like you are both recommending laying the floors in the same direction as existing ones(was my instinct, too) despite the thresholds - the opposite of what the builder wants to do. My Q about the island was really whether or not it's preferable to have wood planks go parallel to the island. The fireplace is opposite the kitchen (hood and fireplace face each other at end of a "great room". and the island is between the two. Wood can either be parallel to the island or to the length of the room leading to fireplace, but not both. Doing the latter also runs the floors the same way as existing. Hope that clarifies somewhat! The thresholds are to adjust for a 3/4" or so difference in floor height. busybme, Good question as to what material we are using. Existing floors are prefinished hardwood, but addition needs to be an engineered product, since it's on a slab. Complicating things are that my existing floors(Mirage) are an unusual width and set of lengths and I really want to match the look. The existing floors also have a microbevel, something i'm not sure I want in a kitchen. I hear it's hard to match old prefinished to new, since the colors will be off after a few years. The answer seems to be to put in site finished engineered floors and stain both floors to match. Still not sure what to do about matching the planks for size and bevel, though.

I’m installing wood plank porcelain tiles 6x24. Which direction should I run the tiles? Should I run it vertical or horizontal as soon as I walk in from the main entry way? Right now I’m thinking of running it Vertical longways from front to back. I shot a video of the house, the floor is bare right now. https://youtu.be/oRStitu8zJ8 There’s a house, exactly the same model nearby that i saw online and they had their wood look tiles running horizontally. I’ll attach pictures. Main entry away Main living room formal dining area or living room 2 Guest bathroom Laundry area kitchen master bath
