Project Planning Pack

If you're considering a major remodel or new construction you'll want to start with your own independent research. This is why we created the Project Planning Pack -  to give motivated homeowners, like you, the information you need, before you talk to an architect or contractor.

Here is some of what we’re giving out for free:

  • Answers to frequently asked questions
  • A self-interview to get a deeper understanding of your project
  • A road map that shows you the design and construction process, from start to finish
  • Our hand-picked list of experts who can help you at each stage of the process
  • Budget worksheet that gives you a ballpark cost estimate for your entire project
  • Project specific checklists
  • Warning signs to watch out for when interviewing architects

We hope this will help you gain greater knowledge of the design-build process and set you up for success.

Your Project Action Plan

When you’re ready to start a bit of preparatory work on your project, but don’t want to commit to a build just yet, choosing one of our Project Action Plans is an ideal solution. These packages encompass some of the first steps with which we start every project, and are essential for determining if and how your project can unfold within your budget. We invest extra time in these initial steps to help you avoid costly changes or delays down the road.

This is also a great way to ensure our relationship starts on the right foot. Beginning with one of these packages allows us to ease into a project together, feeling out if we’re a good fit before making the commitment to work together on the entire project. It’s similar to having a “dating” period before deciding to get married. Much like tying the knot, building a house is one of the biggest and most important decisions you can make… so why rush it? We give you a chance to properly plan for your project and gather all of the necessary information so that you can make an educated decision when committing to the full project scope.
