Frequently Asked Questions About GoodFit Plans

GoodFit homes are designed around the idea that a house should fit the way people actually live—not simply maximize square footage. Every plan emphasizes natural light, efficient use of space, strong connections to the outdoors, and rooms that feel larger than their dimensions. The goal is not simply to build a smaller house, but to build a better one.

Each purchase includes a one-time, limited license to build a specific plan. If you'd like to build the same design 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 full 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 x 17 inches, with a supporting detail book at 8.5 x 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.

GoodFit plans have been built throughout North America in a wide range of climates. Because every building site and jurisdiction has its own requirements, the plans will need to be reviewed and adapted by local professionals to address structural engineering, energy code requirements, and other local regulations. Most jurisdictions require this as part of the permitting process.

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.

Yes. Most 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 often requires more substantial structural changes. In general, major alterations that significantly affect the home’s structure, proportions, or overall character should be carefully considered, as they may compromise both the integrity and 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.

Yes. We provide high-resolution PDF construction drawings with the information needed by your local designer or engineer to prepare permit drawings and site-specific modifications. We do not provide CAD files.

Our plans typically use one of two heating approaches. Earlier designs often feature a gas stove as the primary heat source, supplemented by electric wall heaters in secondary spaces. More recent plans are designed around efficient heat-pump systems.

If you plan to install a radiant floor system or central HVAC, consult with your builder and engineer to determine compatibility. Our homes use 2×6 exterior walls, which allow ample space for insulation and mechanical systems.

Yes. GoodFit plans can often be adapted for modular, panelized, or SIP construction, although they are detailed for conventional wood-frame construction.

If you plan to use these 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.

Construction costs vary widely depending on location, materials, site conditions, and contractor availability. Because our homes are thoughtfully detailed and make efficient use of space, they are not necessarily the lowest-cost homes to build on a per-square-foot basis. However, their modest size often results in a lower overall project cost than larger homes of comparable quality. 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. Our PDF Summary Sheets provide 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.

Yes. All plans, images, and written content are protected by U.S. copyright law and are the intellectual property of Ross Chapin Architects. They may not be copied, adapted, reproduced, or resold without written permission.

Because our plans are digital products and copyrighted intellectual property, we do not offer refunds or exchanges. Before purchasing, we strongly encourage you to confirm that the plan is suitable for your site by reviewing local zoning requirements, setbacks, height restrictions, and other applicable regulations. We also recommend discussing the design with a local builder, engineer, or building official to ensure it is appropriate for your site and budget, and obtaining a preliminary estimate of construction costs in your area before making your purchase.
