Compare multiple options using a consistent checklist that covers functionality, code compliance, and long-term maintenance. The table below helps you compare key aspects across different plan options.
Quick Comparison Checklist

Potential Costs and Budget Considerations
Costs associated with Sullivan house plans vary by size, finishes, and site requirements. Typical price ranges are broad because final budgets depend on local labor rates, material choices, and permitting fees. Use the following figures as general reference points rather than fixed quotes, and confirm with your builder and local suppliers.
Estimated Cost Ranges by Home Size
| Home Size (sq ft) | Estimated Base Construction Cost | Notes |
|---|---|---|
| 1,800 sq ft | $320,000–$420,000 | Typical starter or compact family home |
| 2,400 sq ft | $430,000–$600,000 | Common family home with defined public zones |
| 3,000 sq ft | $540,000–$780,000 | Larger layouts, premium finishes, optional features |
These ranges reflect approximate base construction costs and do not include site work, permits, design fees, or major upgrades. Work with your builder to adjust for local conditions, energy efficiency requirements, and optional features such as enhanced insulation, smart-home systems, or specialized outdoor living areas.
Evaluating Whether a Sullivan Plan Fits Your Project
Choose a plan that aligns with your lifestyle, site constraints, and long-term goals. Consider how often you use each room, whether you need flexible space for work or guests, and how the layout supports future changes such as aging in place or adding another bedroom. Verify code compliance, required permits, and local climate adaptations with your builder or architect early in the process. If you are renovating, review how the proposed Sullivan house plans integrate with existing structures and utilities to minimize disruption and hidden costs.
