Fixed Pricing in a Custom Build: What It Is and Why It Matters

When you’re building a custom home, one of the biggest financial decisions you’ll face is how your builder prices the project. Most use either fixed pricing or cost-plus pricing. Understanding the difference—and how it affects your budget—is essential. In this post, we’ll explain what fixed pricing in a custom build really means and why more homeowners are opting for it.

What Is Fixed Pricing?

Fixed pricing means your builder provides an upfront, guaranteed cost for your entire home build. That price includes materials, labor, overhead, and profit—all locked in before construction begins. The only way your price changes is if you request something different via a formal change order.

Why Fixed Pricing Appeals to Homeowners

• Budget certainty: Know exactly what you’ll pay—before you start.
• No surprise charges: If material costs rise, your builder absorbs it.
• Simplified financing: Easier to secure a mortgage or construction loan.

At Hewn, fixed pricing is how we protect our clients from scope creep and financial stress. You can focus on making meaningful design decisions instead of micromanaging a moving target.

What’s the Alternative? Cost-Plus Pricing

Cost-plus pricing means you pay the builder for actual expenses as they come in—plus a markup. This structure offers flexibility but less certainty. If materials or labor costs rise, your overall bill increases.

Potential Risks of Cost-Plus

• No guaranteed budget: Costs fluctuate with the market.
• More oversight required: You’ll need to stay involved in approvals and reconciliations.
• Room for miscommunication: Definitions of “cost” may vary builder to builder.

When Fixed Pricing Makes the Most Sense

If you’re building for the first time—or just want peace of mind—fixed pricing is a smart choice. It reduces your risk, supports your timeline, and makes financing easier. And when paired with a clear build process, it helps the whole project run smoother from day one.
