Running Cost 1 : Specialized Payroll

Payroll Dominates Fixed Costs

Personnel costs are your primary fixed burden heading into 2026. Wages for your 8 Full-Time Employees (FTEs), including leadership and specialized operators, hit approximately $74,168 monthly. This figure makes staffing the single largest operational expense you face.

Payroll Structure Details

This estimate covers the 8 FTEs needed to run the operation, specifically the CEO, CTO, and the crucial 3D Printer Operators. Calculating this requires knowing the fully loaded cost (salary plus benefits and overhead) for each role, projected for 2026. It’s the biggest single drain on monthly cash flow.

Calculate fully loaded cost per operator.
Factor in required specialized training time.
Use 2026 projections for salary inflation.

Controlling Staffing Costs

Managing specialized payroll means controlling the hiring velocity of technical roles like 3D Printer Operators. Avoid over-hiring before sales volume justifies the fixed commitment. If onboarding takes 14+ days, churn risk rises defintely due to project delays.

Tie operator hiring to printer uptime.
Use contractors for initial scale testing.
Benchmark executive salaries against construction tech peers.

Leverage Required

With $74,168 in monthly payroll, you need significant revenue generation just to cover staff before rent or marketing. Every home sale must generate enough gross profit to cover this fixed cost burden for several days of operation. This is the baseline you must beat consistently.

Running Cost 2 : Facility Leases

Total Facility Commitment

Your total facility commitment hits $32,500 monthly, covering both the factory space for large-scale 3D printers and necessary administrative offices. This fixed cost is non-negotiable for housing the core production assets required to print homes quickly. That's a big number to cover before the first sale closes.

Rent Breakdown

This $32,500 figure breaks down into $25,000 for the factory/warehouse—where the massive printers operate—and $7,500 for the office footprint. You need these specific square footages secured before running the first print job. This is a core fixed overhead you must fund monthly. Here’s the quick math on the inputs:

Factory rent: $25,000/month.
Office rent: $7,500/month.
Covers large printer housing needs.

Lease Management

Since these are fixed costs, reducing them requires long-term planning, not quick fixes. Look hard at the required square footage for the factory floor now versus 18 months out. Don't over-lease space anticipating growth too early; that just burns cash faster. If you can secure a three-year factory lease, you might save 5% on the $25k portion, which is solid money.

Negotiate longer terms for lower rates.
Phase office space needs post-launch.
Ensure factory access supports printer footprint.

Fixed Cost Weight

Facility costs represent a major chunk of your fixed burn rate before sales ramp up significantly. When compared to Specialized Payroll ($74,168) and Marketing ($15,000), this $32.5k rent is roughly 30% of those combined major fixed expenses. It’s a heavy, immovable weight on your early P&L, defintely.

Running Cost 3 : Marketing and Sales

Marketing Spend Baseline

The $15,000 monthly marketing allocation directly supports sales for the Pioneer, Voyager, and Custom Build home models. This spend is fixed overhead, meaning it must be covered regardless of sales volume. To hit break-even, you need enough unit sales to absorb this cost plus payroll and facility rent first.

Cost Detail

This $15,000 covers all advertising and marketing needed to generate leads for the three home offerings. It’s a fixed cost against total overhead, which is substantial given the $74,168 payroll and $32,500 in facility leases. You must map this spend against the expected Customer Acquisition Cost (CAC) for a developer or first-time homebuyer.

Covers lead generation efforts.
Fixed monthly overhead item.
Drives sales for all three models.

Optimization Tactics

Since this is fixed, optimization centers on maximizing lead quality over sheer volume. Avoid broad campaigns; focus on specific developer channels or digital targeting for first-time homebuyers. If lead conversion rates are low, this $15k spend is wasted spend, defintely pushing break-even further out.

Target specific developer needs.
Measure lead quality closely.
Avoid spending on poor channels.

Operational Focus

Honestly, $15,000 is a lean start for marketing high-ticket construction assets like the Pioneer model. You must rigorously track which campaigns generate qualified developer interest versus individual buyer leads. If you can't attribute sales directly, this budget will quickly become a drain on your $121,668 in top fixed overhead.

Running Cost 4 : R&D Materials

R&D Material Cost

The fixed monthly cost for R&D lab supplies is $8,000. This spending directly fuels necessary iteration on your specialized concrete mixes and structural integrity testing. This cost is non-negotiable for product refinement in 3D printed construction. It’s a core expense before you sell the first home.

Lab Supply Details

These $8,000 cover consumables needed to test new material formulations for the structural shell. Inputs are based on required test batches and material procurement schedules, not direct home sales volume. This is a critical fixed overhead that must be covered by initial capital or early revenue.

Covers specialized chemical agents.
Funds small-scale structural tests.
Essential for compliance validation.

Managing Material Spend

Controlling this spend means standardizing test protocols to reduce wasted material runs. Avoid rush orders, which often carry premium shipping fees for specialized components. High-quality initial supplier vetting prevents costly re-testing later on structural performance. We need consistency here.

Negotiate bulk pricing for reagents.
Centralize inventory tracking.
Minimize batch failures.

Cost Visibility

Because this is a fixed $8,000 monthly cost, it must be fully covered by runway capital or early project revenue. It scales with complexity, not necessarily volume, so focus on achieving mix stability quickly. This expense is defintely a prerequisite for securing larger developer contracts seeking proven materials.

Running Cost 5 : Utilities and Power

Powering Production

Utilities are a fixed $4,000 monthly cost covering both the office and the factory floor operations. This budget is essential for powering the large 3D printers and material mixing systems needed for continuous construction output.

Cost Breakdown

This $4,000 monthly utility budget covers electricity for the factory floor, where large 3D printers operate, plus standard office power needs. It is a fixed operating expense, distinct from variable costs like R&D materials. You need actual usage quotes for the specialized machinery to validate this estimate.

Factory power for printers
Office electricity use
Fixed monthly allocation

Managing Power Draw

Since large 3D printers are the main draw, focus on scheduling high-draw tasks during off-peak utility hours if your local provider offers time-of-use rates. Avoid running ancillary mixing systems when the main print cycle is paused. This is defintely a manageable fixed cost.

Check time-of-use rates
Optimize printer idle time
Ensure efficient mixing systems

Scaling Risk

If the factory operations scale rapidly, this $4,000 estimate will quickly become outdated; track actual kilowatt-hour consumption against this baseline starting day one. Unexpected rate hikes present a margin risk if not hedged via contract.

Running Cost 6 : Business Insurance

Insurance Fixed Cost

Business Insurance costs $5,000 monthly, reflecting the inherent liability of using specialized 3D printing equipment on construction sites. This fixed cost covers site risks and operational exposures common in this high-risk sector.

Cost Inputs

This $5,000 monthly premium covers general liability, property damage for the specialized 3D printers, and workers' compensation exposure on job sites. You need firm quotes based on projected annual revenue and equipment valuation to lock this down for the initial year. It’s a crucial fixed cost, similar in scale to R&D materials ($8k).

Covers specialized equipment risks.
Includes site operational liability.
Quote based on asset value.

Premium Management

To reduce this high fixed cost, focus on mitigating site-specific risks that drive up premiums. Strong safety protocols and documented operator training can help negotiate better rates after year one. Avoid bundling unnecessary riders early on; this coverage must remain lean.

Document operator certifications well.
Review coverage annually, not quarterly.
Ensure liability limits match developer contracts.

Risk Reality Check

Given construction's inherent exposure, treating this $5,000 payment as a baseline is smart. If your actual quotes come in significantly higher, it signals deeper underwriting concerns about your operational plan or equipment security. That’s a red flag.

Running Cost 7 : Software and Services

Fixed Tech & Legal Spend

Your essential non-labor overhead for compliance and design totals $5,500 monthly. This covers the $2,500 for core software—like CAD and CRM—and $3,000 for external legal and accounting support needed to operate in construction. That’s $66,000 annually locked in before printing starts.

Software & Services Detail

This $5,500 monthly outlay funds critical operational backbone elements. The $2,500 software budget pays for design tools (CAD), project management (PM), and CRM systems required to manage developers and sales pipelines. The remaining $3,000 secures necessary external legal counsel and accounting oversight for regulatory compliance.

Software: $2,500/month (CAD, PM, CRM).
Services: $3,000/month (Legal, Accounting).
Total fixed cost: $5,500 monthly.

Managing Fixed Service Costs

Don't overpay for unused seats or overlapping tools. Audit your PM and CRM licenses annually; many startups pay for features they defintely don't use yet. For legal and accounting, lock in annual retainers instead of hourly rates to smooth out the $3,000 component.

Audit software seats quarterly.
Negotiate fixed monthly retainers.
Avoid premium tiers too early.

Overhead Context

Compared to your $74,168 payroll, this $5,500 is small, but it’s non-negotiable overhead. If you delay hiring an accountant, compliance risk skyrockets, potentially costing far more than the $3,000 saved. These services support scalable growth, not just initial setup.
