From the Journal
How to Read a Floor Plan
A floor plan is a horizontal slice through the house, taken about four feet above the floor. Once you know that, most of the conventions on the sheet explain themselves. What the dimension strings mean, which sheet answers which question, and the two-minute check to run before you get attached to a plan.
What My Plan Set Doesn't Include, and What You Buy Locally
Stamps, site plans, engineered framing, mechanical and plumbing are not in any stock plan set, from anyone. What is missing, who provides each item locally, and the questions to ask your building department before you spend anything.
Questions people ask before they buy
A full construction set: cover sheet with general notes, foundation plan, dimensioned floor plans for every level, all four exterior elevations, a cross section, roof plan, electrical plans, and door and window schedules. It comes as a PDF, as PDF plus CAD for your engineer, or as Chief Architect files.
Plan on it. Every set should be reviewed by a licensed engineer for your soil, wind and flood loads, and the elevated plans on piers or pilings need supplemental structural drawings. Some permit offices require a local stamp. We do not provide stamps, but we may be able to put you in touch with an engineer in your area.
The plans are drawn to the 2021 IRC. Your county may add amendments or ask for extra items, so expect to supplement the set with engineering, framing plans, a site plan and HVAC or plumbing drawings from local trades.
Yes. Minor changes are drawn in house: overall dimensions, foundation type, roof pitch, windows and doors, interior layout changes under 200 square feet, porches and garages. Major redesigns are quoted separately. Estimates are free; use the modification request form.
A reduced, not-to-scale set of the floor plans, elevations, schedules and the spec sheet, for $75. It is for judging the design and getting a builder's budget number, not for permits or construction. The $75 comes off the construction set for the same plan within 12 months.
As a download after checkout; nothing ships. Each plan is licensed for one build at your address. If you want to build it again, ask about additional build licenses.
