Union Modular 2160 is a $417,500 construction-scope concept for a 2160-square-foot modular family ranch. This guide helps U.S. readers compare the intended size, rooms, sample cost allocation, and savings milestones. It is not a home listing, contractor bid, appraisal, or ready-to-build plan.
Planning target: $417,500 covers only the illustrative house scope and allowances described below. It is not a guaranteed purchase price or turnkey construction price. Land, major site work, permits, utility connections, financing, and professional services are excluded.

Exterior and floor-plan concept
The exterior uses warm beige factory siding panels with charcoal trim, a low-pitch asphalt gable roof, and a small factory-built entry canopy. The image is a conceptual visualization created for design inspiration, not a photograph of a property offered for sale.
The central great room connects the kitchen and dining area. The primary suite sits apart from the secondary bedrooms, while laundry, storage, and the remaining bathrooms cluster around short circulation paths.
Best fit: A household needing guest, work, or multigenerational flexibility along with three full bathrooms.

What the target assumes
This target assumes regional standard-finish construction target, a straightforward buildable site, standard-grade materials, competitive local bids, and limited change orders. A custom turnkey contract in a high-cost U.S. market can be substantially higher.
- A code-appropriate structure using practical spans, efficient plumbing runs, and stock-size windows and doors.
- Standard cabinetry, counters, flooring, lighting, plumbing fixtures, and appliances rather than luxury selections.
- The garage allowance applies only as described above; oversized bays, workshops, bonus rooms, and elaborate driveways are separate.
- Every allowance is replaced with current local quotes before land purchase, financing, or construction.
Costs not included
- Land, closing costs, loan interest, lender fees, property taxes, insurance, or real-estate commissions.
- Survey, clearing, demolition, grading, driveway, drainage, retaining walls, rock work, or contaminated soil.
- Utility extensions and hookups, septic, well, municipal impact fees, or unusually long service runs.
- Permits, plan review, inspections, architecture, engineering, energy testing, or construction documents.
- Detached structures, pools, major decks, fencing, furnishings, window treatments, or finished landscaping.
A simple savings target
Someone choosing to save the full concept amount in cash would need approximately:
- 10 years: $3480 per month for 120 months
- 20 years: $1740 per month for 240 months
- 30 years: $1160 per month for 360 months
These are arithmetic examples only. They do not model investment returns, inflation, taxes, mortgage terms, future price changes, or whether cash saving is an appropriate financial strategy.
Before using this model
- Confirm zoning, minimum size, setbacks, access, utilities, and design rules with the local jurisdiction.
- Price the land, site, permits, foundation conditions, utilities, and professional work separately.
- Have qualified local professionals verify structure, energy performance, fire safety, egress, accessibility, electrical, plumbing, and mechanical systems.
- Compare at least three current written bids using the same scope and retain an additional real-project contingency.
Why location can change the result
Labor rates, material availability, codes, climate loads, taxes, and site conditions vary widely across the United States. National data provide context but cannot price a specific project; this model depends on its stated size, standard finishes, efficient design, and exclusions.
