Understand the True Cost to Build Your Custom Home
Know true costs before designing your dream custom home.
Start Your Custom Home Journey With a Realistic Budget
A successful custom home begins with an honest understanding of cost. Long before selecting finishes or sketching floor plans, you need a realistic budget that reflects the true complexity of building in Northern Virginia. With 25 years of integrated design-build experience, we help you establish this clarity from the start. When your budget and your goals are aligned, the entire process—from design decisions to builder conversations—becomes more efficient, more informed, and far more predictable.
How Much Does It Cost to Build a Custom Home in Northern Virginia?
Our custom homes start at $450 per square foot, which reflects the baseline cost for a Modern Simplicity Design from our Budget Calculator. This starting point includes everything required to design and build your home:
-
Architectural design
-
Structural engineering
-
Civil engineering
-
Permitting
-
Full construction of your home
Many of our clients choose homes around 5,000 square feet, typically including:
-
5 bedrooms
-
4.5 bathrooms
-
2-car garage
-
Modern, open layouts rooted in our Vacation Style Living® philosophy
At this baseline, you can expect a starting investment of approximately $2.25M for the home itself before land or site-specific requirements.

What’s Not Included in the Baseline Cost?
The $450/sqft starting point does not include:
-
Cost of the land / lot
-
Site development costs, which typically add 10–20% depending on:
-
Topography
-
Utility access
-
Stormwater requirements
-
Driveway length
-
Retaining walls
-
Tree removal
-
Septic/well requirements
-
Your lot is the single biggest cost variable. We evaluate these factors early in the design process so your budget remains realistic and predictable.
Why Costs Vary Above the Baseline?
Because your home is 100% custom, the final price is influenced by:
-
Architectural complexity
-
Level of finishes
-
Extensive glazing or specialty materials
-
Outdoor living spaces & hardscaping
-
Pools & integrated amenities
-
Advanced mechanical systems
-
Structural enhancements
-
Unique lifestyle features
Our design-first methodology ensures you understand every cost driver before we build—no surprises.
