    We can generally set up an appointment within a week! The first step in finishing your basement is to contact us. You will be speaking with one of our staff who will arrange your free in-home consultation.
  • Our First Appointment
    The #1 priority of our first visit is to gain a full understanding of your needs for the space. How you will use your basement? We’ll share our philosophy around how a basement should flow and provide some design ideas and options. We want the space to be an additional level of your home and not feel like a basement. We’ll take measurements and can answer any questions you have about your options and what things cost.
  • Basement Design
    We’ll spend the time needed to draw up a layout of the basement based on everything we spoke about during the initial meeting.
  • Basement Ideas
    We’ll work out several plans which capture the smartest design for the space within the desired budget. This is when our years of experience really bears fruit. We’ll show you basement ideas that you’ve never considered! Be ready to roll up your sleeves in this creative meeting. You are an important part of the design team and by incorporating your feedback we will take the best elements to create the “one” space plan best for your needs.
