Our Design-Build Process
A Clear Process From First Call to Final Walkthrough
Here is the real world flow most clients experience:
Define
Discovery Call
We have an initial phone call to determine if we are a good fit for each other. We will talk about the location, scope, budget, timing, etc.
Initial Meeting
At our in-person meeting to get to know each other and about the project. We start talking specifics about what a customer's wants and needs are and develop a rough plan.
Ballpark Review Meeting
Based on our meeting we will create a general scope, price, and then meet to review everything with you.
Design And Site Agreements
After the review meeting a design agreement is presented to develop detailed plans. A site engineering agreement is presented to get a head start working on any required site engineering needs while we finalize plans and specifications.
Refine
Detailed Prints
After a signed design agreement we will create plans for the project. This will include a full set of plans and 3D renderings.
Detailed Specifications
Once we have a plan we will create a detailed specification sheet and price based on the plans.
Meeting To Review
In this review meeting we will pull up the plans and 3D model for the customer to visualize. We can make changes to the plans and model in real time. Also during this meeting we will review all the specifications to make sure everything is captured.
Site Meeting
We will then set up a site meeting. For new homes it is to see how the house will fit on the land and how the grade will work around it. For remodels & additions it is to confirm measurements and verify how all of the mechanicals will connect.
Plan & Spec Updates
We will make updates based on the site meeting information and customer's wants/needs as many times as it takes until the customer is happy.
Contract
Only once site engineering is complete and the customer is happy with the plans, specs, & price will we present a contract for a customer to sign.
Build & Deliver
Selection Meeting
This is when we will choose all the finishes for the project. There is a lot to pick out so we typically break it up into several different meetings.
