Often signed during or immediately after Preconstruction—before final selections or engineering are complete
Cost-Plus contracts are designed for clients who want to move forward proactively while maintaining full transparency and flexibility throughout the process.

- You sign the construction agreement during or after Preconstruction
- We bill actual costs to the project—nothing hidden or padded

Best For:
Smaller remodels or projects with a clearly defined scope
When It’s Used:
After the Preconstruction Planning & Investment Package is completed and final drawings, selections, and engineering are finalized
Fixed Fee contracts are most often used for smaller or more straightforward projects. These agreements offer a single, set price for your build based on finalized construction documents and specifications.
How It Works:
- You complete the Preconstruction Planning & Investment Package with our team
- After all plans, selections, and engineering are finalized, we issue a Fixed Fee contract with a set total project cost
- Any changes after signing are processed as change orders
- Scope and pricing are locked in prior to constructionKey Features:
- Predictable total cost
- Clear scope and expectations
- Ideal for projects where no major changes are expected after design is completeLimitations:
- Requires full design and selection completion before signing
- Less flexibility to make changes once construction begins
- Slower start—cannot begin construction or procurement until contract is signed

Our Design-Build Process
We begin by learning about your vision, lifestyle, and goals for your home. Then we connect you with architects, engineers, and our in-house interior designer to shape the plan. Every detail is considered early on so we can build with confidence and clarity.
While the design comes together, we gather trade bids and create a transparent, line-item estimate. You’ll know exactly where your investment is going, with no surprises. Once approved, we schedule work, order materials, and prep your site for a smooth start.
From demo to final walkthrough, we manage every phase with precision and care. You’ll receive weekly updates, site walks, and open communication throughout construction. And even after move-in, we’re here with dedicated support and a clear warranty plan.
