More inside than out.

We currently accept projects in New York, New Jersey, Oregon, Washington, Florida, and California. Each project begins with a free site feasibility review where we confirm local code requirements and project viability for your specific jurisdiction. If you're outside these areas, reach out — we're expanding and may be able to accommodate your project on a case-by-case basis.

Your package includes design & engineering with one free design revision cycle, stamped permit-ready drawing sets, full-build construction consulting, general contractor training, construction kit shipping (NY, NJ, OR, CA, WA), the SIPs structural panel kit and steel + insulation interior framing, windows and exterior doors, and weatherproofing and functional membranes. Roofing, siding, interior finishes, flooring, door & trim, and kitchen, storage, and bathroom casework are available as optional add-ons, and permitting submission can be handled on your behalf.

The package does not include foundation and site work, on-site construction, utilities hookups, or MEP systems (electrical, plumbing, HVAC). Interior finish and casework installation and lighting fixtures are also handled on site rather than included in the kit. These are coordinated by your local general contractor — we provide consulting support throughout.

Yes, within reason. Every package includes one cycle free design revision to adapt the plan to your site and preferences. Standard customizations include mirroring the floor plan, minor window repositioning, adding or removing windows, and entry door configuration (single or double, with an optional full-height glazing system). Structural changes that affect the SIPs panel layout may require additional engineering review and are quoted separately. Our team will advise during your feasibility review what's possible within your budget.

Yes — we supply the kit, and on-site construction is coordinated by a local general contractor. You're not on your own finding one, though: we maintain a network of trusted local general contractors, architects, and structural engineers who are familiar with our building system, and we can connect you and help coordinate throughout your build.

From your initial reservation to move-in, most projects complete in 20–40 weeks. The largest variable is local permitting, which varies significantly by jurisdiction. Factory fabrication and delivery takes 14–16 weeks once production begins. Shell assembly with the SIPs system typically takes 1–3 weeks on site — significantly faster than traditional stick framing. Your feasibility review will include a project-specific timeline estimate based on your location and design.

Projects are initiated with a 25% deposit of the total package price, which begins the design and permitting phase. The remaining balance is paid in two installments: 50% to enter factory production, and 25% prior to shipping. Deposits are fully refundable within 7 days of payment with no questions asked. After 7 days, deposits are non-refundable but transferable — you may apply the full deposit toward a different floor plan or defer your project start date by up to 12 months. Cancellations after production has commenced are non-refundable.

In most cases, no. We provide complete permit-ready drawings as part of our service. These construction documents include the specifications your local contractor needs to build the project according to the design. For most states we serve, we also provide stamped drawings. If your project is located in an area outside our stamping service coverage, we can connect you with one of the architects in our trusted network to review and complete the required stamping for your permit application.

Structural Insulated Panels (SIPs) offer three key advantages over conventional stick framing. First, energy efficiency: SIPs provide continuous insulation with no thermal bridging, reducing heating and cooling loads by up to 60% compared to standard 2×6 stud construction. Second, speed: because panels arrive pre-cut and numbered, a skilled crew can stand the structural shell of a compact build in as little as one day. Third, structural strength: the composite panel system creates a rigid, airtight envelope that outperforms stud framing in wind and load resistance — important for both ADU and retreat applications.
