What do I receive when I purchase a GoodFit house plan?
Each purchase includes a one-time, limited license to build a specific plan. If you’d like to build more than once, a separate license must be purchased for each additional build.
With your license, you’ll receive access to a PDF download of the construction drawings for the plan. You may share this file or printed copies with your builder, local permitting authorities, or other professionals involved in your project.
Most plans are formatted at 11×17 inches, with a supporting detail book at 8.5×11 inches.
The plan set includes:
• Foundation Plan
• Floor Plans
• Framing Plans
• Building Sections
• Building Systems
• Elevations
• Electrical Plans
• Construction Details
• Specifications
• Window & Door Schedules
Note: A materials list is not included.
Do the plans include structural engineering? Will they need to be engineered for my site?
GoodFit house plans are drawn to meet generally accepted building standards and include suggested structural components for reference. However, they are not engineered for any specific site or region.
Because local conditions—such as soil type, frost depth, wind and seismic zones, and building codes—vary widely, you will need to have the plans reviewed and adapted by a licensed structural engineer familiar with your building site. This is often a permitting requirement and is essential for safety and compliance.
If you’re considering any modifications to the plan (such as changes to the foundation or HVAC), this is also the right time to consult your engineer or contractor to incorporate those changes.
Can I make changes to the plans?
Yes. Many homeowners make some adjustments to better suit their needs.
We recommend keeping modifications relatively simple—for example, adjusting interior walls, changing window or door placements, or adding or modifying a porch. Extending the building along its ridge line is typically more straightforward and structurally feasible than widening it, which can involve more complex framing changes and may require significant structural re-engineering. In general, major alterations that impact the home’s structure, proportions, or overall character are discouraged, as they can compromise both the integrity and the intent of the original design.
While we do not offer custom modification services, we can provide mirrored or flipped versions of a plan for a $250 fee.
If you’re planning modifications, consult with a local designer or engineer. Any structural changes should be reviewed and stamped by a professional engineer during your permit process.
Are CAD files available?
No. CAD files are not available. However, we can provide a high-resolution PDF file that can be us3d as a base for modifications or printed as needed for construction and permitting.
What kind of heating and cooling systems do the plans support?
Many of our GoodFit plans have been designed with a gas heating stove as the main heat source for the main floor living areas, and electric wall or baseboard heaters in secondary rooms. Some plans include mini-split electric heat pump systems for heating and cooling. If you and your builder are considering a different system, such as radiant floor or central heating & air conditioning, you should discuss these possibilities with your engineer or builder to ensure their fit with the building and structure.
Are the plans suitable for modular or SIP construction?
Yes, they can be adapted, although the plans are drawn for standard wood-frame construction. If you plan to use modular, panelized, or SIP systems, consult with local manufacturers to assess feasibility and cost. It’s wise to do this before purchasing a plan, especially if alternative construction is central to your project.
How much will it cost to build?
Construction costs vary widely depending on location, materials, site conditions, and contractor availability. While our homes are generally smaller than average, they often include high-detail design and quality finishes that place them just above the mid-range in cost per square foot. That said, we also offer plans designed with affordability in mind—homes that balance thoughtful design with simplicity, making them more accessible to a wider range of budgets.
To get a realistic sense of construction costs, we recommend talking with local builders who understand current pricing and conditions in your area. We can provide PDF Summary Sheets with key dimensions and plan details to help guide those conversations. If you’re looking for a more in-depth assessment, you can also request a study set (available for $250), which includes more detailed drawings and is credited toward the purchase of a full plan license.
Remember that prices fluctuate. Getting an early estimate won’t eliminate uncertainty, but it will help you avoid designs that are likely to exceed your budget.
Are the plans or images on the site copyrighted?
Yes. All plans, images, and written content are copyrighted and are the intellectual property of Ross Chapin Architects. Unauthorized copying, adaptation, sale, or transfer is a violation of federal copyright law and may be subject to fines up to $100,000 per offense.

What is your refund policy?
Because our plans are digital products and copyrighted intellectual property, we do not offer refunds or exchanges.
Before purchasing, we recommend that you:
• Confirm the plan meets local zoning and site constraints (setbacks, height restrictions, etc.)
• Consult with a builder, engineer, or inspector to discuss feasibility
• Review estimated construction costs for your location
