Questions, answered

Everything you want to know before you order.

Yes. Every order is a complete construction drawing set, floor plans, elevations, foundation, roof, electrical and plumbing, and most U.S. counties accept them directly for permit applications. Some jurisdictions require a locally licensed engineer or architect to stamp the drawings before submission; if yours does, we provide everything that professional needs to review and stamp.

Revisions are free. We revise your plan, as many rounds as it takes, until the layout matches your brief and you’re happy. You work directly with your designer the whole way, with no per-change fees.

Your complete plan set is delivered in about 7–11 business days. After checkout, a designer reviews your brief and reaches out within 1 business day to confirm details before drawing begins.

A complete professional package, typically 30–40 pages: ground floor plan (imperial + metric), site plan, roof & framing plan, exterior elevations (all 4 sides), electrical plan, door & window schedule, plumbing plan, structural notes, interior sections, plus 3D interior and exterior renders, all delivered as a PDF by email.

Yes. Once delivered, the plan set is yours to build from, print, and share with your contractor, lender or local building department. There are no subscriptions or recurring charges, it’s a one-time payment.

Just email us. Revisions to your plan are unlimited and included. Only a completely new design (a different size or number of floors) would be a new plan. Your files stay on record so we can pick up right where we left off.

Traditional firms bill hourly or a percentage of your build, which often adds up to $10,000+ for a custom home. Our in-house architecture team works only on residential plan sets with a streamlined process, so you get a complete drawing set at one flat price from $799, no hourly billing and no extra fees.
