What is the process and how long does it take to modify a plan?

Modification jobs vary depending on the amount of changes, the size of the home, and our current workload.

Once the initial house plan modifications are made, you will receive a preliminary of the changes to approve or correct. Upon approval, the construction documents will be adjusted to the modifications and the plans will be finalized. We will deliver your newly modified plans to you once we have invoiced and received your final payment. Changes not included in the original estimate will result in additional fees and time.

On average, it take up to 2 weeks to modify a plan from start to finish; however, it may take longer depending on the complexity of your changes. An estimated time of completion will be included in your estimate.
