One of the first questions many homeowners ask is:
“Can you give me a price to build my home?”
It’s a fair question.
The challenge is that a truly custom home cannot be priced accurately until your builder understands exactly what they’re building.
Think about it this way.
If you asked three builders to price “a 2,800-square-foot custom home,” you would likely receive three very different numbers. Why? Because no one knows the details yet.
What style of home are you building?
What level of finishes do you want?
Will the home sit on a crawl space, basement, or slab?
Do you need a well and septic system?
Will there be vaulted ceilings, large windows, or outdoor living spaces?
Without those answers, any price is simply an educated guess.
That is why we believe every successful custom home should begin with a Pre-Construction Planning Agreement (PCP-A).
A Pre-Construction Planning Agreement is a structured planning phase that takes place before you sign a construction contract.
Instead of rushing into construction, you and your builder work together to develop every major aspect of your project before final pricing begins.
Think of it as creating the roadmap before starting the journey.
By the time pre-construction is complete, everyone understands what will be built, where it will be built, how it will be built, and what it will realistically cost.
Because custom homes are exactly that: custom.
Unlike production homes, every custom home is different.
Before a builder can confidently establish a fixed construction price, they typically need to understand:
Your vision
Your budget
Your land
Your building plans
Structural engineering requirements
Site conditions
Product selections
Specifications
Trade partner pricing
Without this information, builders are forced to make assumptions.
Assumptions often become change orders, delays, and budget surprises.
Planning first helps avoid those problems.
Every builder’s process is different.
At McMahon Custom Homes, pre-construction is where your ideas begin to take shape.
Depending on your project, we may:
Learn about your family’s goals and priorities.
Establish a realistic investment range.
Review or help you select your land.
Coordinate surveys and site evaluations.
Arrange soil testing and septic design when needed.
Work with our design partners to develop your building plans.
Refine your home’s layout.
Develop detailed specifications.
Guide you through major product selections.
Coordinate pricing with trusted trade partners.
Prepare a realistic fixed-price proposal.
This planning process reduces uncertainty before construction ever begins.
That’s perfectly fine.
Many homeowners come to us with plans they’ve already purchased or had designed.
Rather than starting over, we incorporate those plans into the pre-construction process.
We’ll review them together, identify opportunities for improvement, confirm they align with your goals and budget, and prepare them for construction pricing.
Our goal isn’t to replace your plans.
Our goal is to make sure they’re ready to build.
This is one of the most common questions we receive.
The simple answer is that developing an accurate custom home takes hundreds of hours of professional work before construction begins.
During pre-construction, multiple professionals may contribute to your project, including:
Designers
Engineers
Surveyors
Soil evaluators
Drafting professionals
Estimators
Trade partners
Your builder
Rather than providing a rough estimate based on assumptions, a Pre-Construction Planning Agreement invests that time upfront so you receive accurate information before making one of the largest financial decisions of your life.
Although every project is different, homeowners typically finish pre-construction with:
Building plans ready for permitting
A detailed specification package
Site planning documents
Survey information
Well and septic documentation when required
Product selections
A realistic construction budget
A fixed-price proposal for construction
Instead of simply receiving a number, you receive a fully developed project.
That’s your decision to make.
One of the advantages of a Pre-Construction Planning Agreement is that you’re investing in your project, not simply paying for a sales process.
If you decide another builder is a better fit, you’ll still have valuable work completed that can help move your project forward.
More importantly, you’ll make that decision before construction begins, not halfway through building your home.
We believe both the homeowner and the builder should have confidence they’re the right fit before entering a long-term construction relationship.
Building a custom home is a major commitment.
Depending on the project, you may spend:
Several months planning.
Eight to eighteen months in construction.
One year working through warranty items.
Decades living in the home.
That relationship deserves more than a quick estimate and a handshake.
The more planning completed before construction begins, the smoother the building experience is likely to be.
We believe so.
A well-executed pre-construction process helps:
Reduce budget surprises.
Improve pricing accuracy.
Clarify expectations.
Identify site challenges early.
Create better building plans.
Improve communication.
Build trust before construction begins.
Most importantly, it gives you the confidence to move into construction knowing everyone is working from the same plan.
At McMahon Custom Homes, we believe great homes are built twice.
The first time is through thoughtful planning.
The second time is during construction.
Our Land-to-Keys™ process begins with a Pre-Construction Planning Agreement because we believe investing time upfront leads to a smoother, more enjoyable building experience and a better home in the end.
If you’re planning to build a custom home in Goochland, Richmond, Chesterfield, Midlothian, Henrico, Hanover, Powhatan, or the surrounding areas, we’d be happy to walk you through our pre-construction process and answer any questions you have before making a commitment.
Because the best custom homes don’t start with construction.
They start with a plan.
