Understanding New Construction Home Pricing

When Price Per Square Foot Works—and When It Doesn’t: A Custom Home Build Framework

There’s a common misconception in the home building world: that price per square foot is the universal standard for estimating a build. The truth is, that metric only applies when you’re dealing with a spec home—a property that comes pre-packaged with a set plan, selections, and pricing. That model works for many consumers because it narrows down the variables to one digestible number.

But here’s the raw reality: a truly custom home is a different beast. So let me break it down for you!

A Custom Home vs. A Spec Home

Spec Home Builds:
In a spec home, everything is predetermined—plans, materials, and even finishes are fixed. This allows builders to offer a set price per square foot that most consumers find relatable and easy to understand. If you’re leaning toward this model, you’re likely looking for a home with some customization, but ultimately, you’re working within a defined framework.

Note: In these cases, separate evaluations for things like lot prep, utility hookups, and site-specific costs (water, sewer, septic, or well) will be added in once you have the lot.

Truly Custom Home Builds:
A genuine custom home means you’re choosing every element—from the layout and design to the finishes and details. This isn’t something that can be slotted into a neat price-per-square-foot package. Instead, it starts with a custom home build pricing fee (ranging typically from $2,500 to $10,000, depending on the builder). At Landmark Building, this is a $5000 flat fee to have your entire custom home built and priced out. 

In this world, the beauty and challenge lie in the endless options and nuances that you, the client, bring to the table. Your vision drives every customization, making the final cost a detailed tapestry of decisions rather than a simple, one-size-fits-all metric.

Breaking Down the Big Cost Drivers

Whether you’re looking at a spec build or a truly custom home, there are always three main cost drivers to keep in mind:

1. The Lot: The price per square foot for the home usually excludes the land. Lot purchase costs, survey fees, lot prep (like clearing, grading, and dirt hauling), and utility hookups (water, sewer, gas, electric, or even well/septic systems) can add substantial expense.
   ***f you already own the lot, you can have it evaluated for custom lot pricing—giving you a complete picture of what the entire project will cost.
   

2. The Plan: With spec builds, the plan is pre-designed, and the price per square foot encompasses a standard approach. But with a custom home, the plan is your starting point—one that evolves as you select different options. Every twist and turn in your design (from foundation corners to unique room shapes) means more complex work, more material, and ultimately, higher costs.
   

3. The Selections: In a spec home, basic finishes are included in the price, with limited customization. However, in a truly custom build, every fixture, appliance, and detail is chosen by you.

   • Builder Grade: ~$225+ per square foot for off-the-shelf, code-compliant finishes.
     

   • Premium Grade: ~$250+ per square foot, offering higher quality and more customization
     

   • Custom Grade: ~$350+ per square foot for truly bespoke options that transform your home.

Finding Your Fit

Understanding these distinctions is crucial. If you’re eyeing a quick price per square foot, you might be leaning towards a spec home model—with some room for limited customization. But if you want to drive the design of your home entirely, you’re stepping into the truly custom realm, where initial pricing is more about setting the stage for a detailed, personalized process than about a fixed rate.

At Landmark Building, we recognize the need for both. We offer pre-set collections for those who prefer the spec-built model, and our detailed custom pricing process for those who want to tailor every aspect of their home. We believe in clear communication so that you know exactly what you’re getting—and you can avoid the frustrations that often arise from vague estimates.
