If it's time for a new quote, the following considerations will be helpful to get you started:
Dimensions
Measure your walls and floorspace. Try your best to capture the lengths of the walls and ceiling height. Include any windows or doorways. This does not have to be a full blueprint.
Style vs. Function
Finding the balance between style and function will lead to some important decisions about your space. Consider what you and your family value most in your home.
Appliances
If you're purchasing new appliances or hanging on to your current ones, their dimensions will be helpful in starting the quoting process (please include sinks and faucets).
Trendy or Timeless
Trendy designs are a fun way to express personality in your home. If you're thinking of selling your home in the near future, you might consider designs with more neutral selling features.
