Our Process

Our Pre-Construction Checklist outline for the typical steps normally assumed prior to construction activity. This checklist will walk you step by step through the design phase through beginning of construction..


  • We review our building process with you and discuss the timeline for your build.

  • If you have a design in mind already, we will discuss your wish list and priorities for your home design.

  • Finally in this phase, we will look at your budget as well as direct you toward qualifying for construction loan financing if needed.



  • Together we will review your floor plan sketch and/or your architectural drawings.

  • We will then walk the lot or location of the project with you.

  • Environmental Health applications / well & septic (if applicable) will be submitted.

  • Lastly we will review zoning and site setbacks (if applicable)


Construction projects are always a creative and collaborative process, so we partner with seasoned Professionals and Craftsmen to ensure a smooth build:

  • Architect (if applicable)

  • Surveyor

  • Structural Engineer

  • Mortgage Lender (if applicable)



  • We review the finalized floor plans and preliminary site plan with you and confirm the final design direction.

  • We discuss material, designs and furniture needs.

  • Lastly we will review and fine-tune all specifications such as Siding/Brick/Shingles Veneer, Exterior Doors/Windows, Garage Door Design, Shutters, etc., that will assist us in narrowing down your budget figures.



  • During this phase, final plans will be reviewed and confirmed.

  • We will guide you in your budget allowance figures for those items such as Cabinets, Counter-tops, Appliances, Flooring, Lighting, and Plumbing Fixtures.



  • After confirming all details of your build project, we will execute the contract and specification agreement.

  • Also we will discuss the utilization of our Online Construction Management Software that will further enhance your home building experience.



  • We will complete permit applications and make submissions to municipality for all building and mechanical permits required.
