Frequently Asked Questions

FAQ

Can I use these plans to get a Permit?

The Build Package is designed to support permitting, but it will need to be reviewed and adapted to your specific site and local code requirements.

Dwelly is licensed in Rhode Island, Massachusetts, and New York, and we offer additional consulting services to help move your project forward. This can include:
– Reviewing and adapting the plans as a local architect
– Preparing a site plan
– Virtual strategy sessions to guide you through permitting

Will this design work on my property?

That depends on your local zoning, setbacks, and site conditions.
The Planning Package is the best place to start—it gives you what you need to quickly assess fit before committing to a full build. We also offer consulting if you’d like help evaluating your property.

Can I customize the design?

Yes. The plans are designed to be flexible.
Smaller adjustments can typically be made by the Dwelly team or in coordination with your local architect or contractor. Larger changes may require a more custom design process.

Is this designed for aging in place?

Yes. The Field House includes a zero-step entry and an ADA-adaptable kitchen and bathroom layout, making it well-suited for aging in place or long-term flexibility.

What’s included in “license to build”?

The license gives you the right to construct The Field House for one project using our drawings.
The design itself remains the intellectual property of Dwelly and cannot be reused or resold.

Do I need a structural engineer?

The Field House is designed to simplify the structural process and align with common residential construction practices.

The roof structure uses prefabricated wood trusses, which are typically engineered and stamped by the truss manufacturer or lumber supplier as part of their scope.
The primary framing is based on IRC prescriptive methods, which are widely accepted in residential construction.

However, final structural requirements are determined by your local building department and site conditions. In most cases, a local professional will be needed to:
– Verify soil conditions and foundation design
– Confirm compliance with local codes
– Coordinate any required structural engineering due to site or location constrains

Dwelly can help guide this process or coordinate with your local team as needed.

Do you provide mechanical, electrical, or energy engineering?

The plans include conceptual mechanical, electrical, plumbing, and lighting layouts, along with a high-level performance strategy.
These systems are typically developed using a design-build approach, where your contractor and their subcontractors finalize equipment selection, sizing, and installation based on your specific site, budget, and local requirements.

Energy compliance (such as code-required calculations or certifications) is usually completed by a local energy consultant or HERS rater, depending on your jurisdiction.
Dwelly provides a coordinated design framework and can offer consulting to help guide these decisions and support coordination with your local team.

How much does it cost to build an ADU like this?

Construction costs vary by location, site conditions, and contractor, but most ADUs of this size fall within a broad range of $125-250k depending on finishes and complexity.
The Planning Package is designed to help you get accurate, local pricing early in the process.

What do I still need before I can build?

In addition to the drawings, most projects require:
– A site plan specific to your property
– Local code review and permitting approvals
– Structural, MEP, and energy coordination as required by your jurisdiction
– A contractor to price and build the project

Dwelly offers consulting services to help guide you through these steps.
