Chicken and egg

Now we have started the build Saturdays have taken on a new dimension.  Tiles, bathrooms, fires, knobs, doors, toilets, wood floor, and so on and so on.

The bit we are struggling with is there is nothing to latch on to.  That is to say, we meet a kitchen designer and cannot give him what materials/colours we have used elsewhere because we haven't chosen any.

Does that mean everything else is based off what we choose for the kitchen?

We are stuck in a loop and need to break it.  If the kitchen designer cannot break the circular thinking we are currently stuck in I am going to buy a toaster, everything else in the house can will have to match that.
