Floor Plans vs. Structural Building Plans
Floor (architectural) plans and structural building plans are two completely different animals and should not be confused with each other. Architectural plans show what your home will look like, structural plans detail skeletal aspects and structural stability. In jurisdictions requiring structural plan reviews and inspections floor plans only will not get one a permit to build.
According to Wikipedia (aka sum of all human knowledge):
“A floor plan is an overhead view of the completed house. On the plan, you will see parallel lines that scale at whatever width the walls are required to be. Dimensions are usually drawn between the walls to specify room sizes and wall lengths. Floor plans will also indicate rooms, all the doors and windows and any built-in elements, such as plumbing fixtures, cabinets, water heaters, furnaces, etc. Floor plans will include notes to specify finishes, construction methods, or symbols for electrical items.

Elevations are a non-perspective view of the home. These are drawn to scale so that measurements can be taken for any aspect necessary. Plans include front, rear and both side elevations. The elevations specify ridge heights, the positioning of the final fall of the land, exterior finishes, roof pitches and other details that are necessary to give the home its exterior architectural styling.”

Hansen Pole Buildings offers custom barndominium, shouse (shop/house), and post frame home floor plans and elevation drawings. Plans start at $695 for custom designed floor plans with elevation drawings for a single floor. When you invest in your new Hansen Pole Buildings kit for this building you will receive a discount of $695 regardless of what optional services you select.

Floor plans and elevation drawings need NOT be done by a Registered Professional Architect however an experienced Building Designer should be one’s least level of acceptability. Lenders (and their appraisers) typically require professionally produced floor plans and elevation drawings for finance approval purposes.
Structural Building Plans (unless following International Residential Code’s (IRC) very narrow prescriptive requirements) should always be prepared and sealed by a Registered Design Professional (RDP – architect or engineer). Structural building systems other than most stick frame (stud wall) are outside IRC parameters and require an RDP’s participation to assure conformance to minimum Code requirements. These would include PEMB (Pre-Engineered Metal Buildings), Pole or Post-Frame, Weld-up Steel and ICFs (Insulated Concrete Forms).
Generally included in structural building plans are:
A section cutting cuts through dwelling and location of this ‘cut through’ is noted on floor plans. It describes how building will be constructed and discusses how internal finishes are to look. Sections are used because they explain certain conditions in more detail. These conditions may include ceiling height, ceiling type (flat or vault), and window and door dimensions.

Foundation plan, including dimensions and locations for footings.
Framing plan, for walls, including lumber sizes to be used.
Sub-floor Plan (for wood floors) gives details of how this area will be constructed and how services will be arranged.
Roof plans, including type, pitch (roof slope) and framing.
Detail drawings, such as columns and all connections.
Structural Layouts.

Our buildings are designed for average physically capable person(s) who can and will read instructions to successfully construct their own beautiful buildings (and many of our clients do DIY). Our buildings come with full 24” x 36” blueprints detailing locations and attachment of every piece, a 500 page fully illustrated step-by-step installation manual, as well as unlimited technical support from people who have actually built post frame buildings. We have found those who DIY almost universally end up with a better finished building than any contractor will build for them (because you will actually follow plans and read directions, and not take ‘shortcuts’ in an attempt to squeeze out a few extra dollars of profit). We’ve even had couples in their 80s assemble our buildings!
Being able to pass a blower test is less a function of the structural system than it is of properly constructing a well-sealed building envelope. It is also not yet a nationwide mandate – Florida just happens to be one of a handful of states where it is required. By using two inches of closed cell spray foam insulation on all surfaces and properly installing all doors and windows you should have no issues with passing a blower test. Our third-party engineers do a thorough check on every member and connection to ensure all are adequately designed to resist the imposed loads – including column uplift. Screw tie downs will not be required in order to resist columns uplifting (at least not by our engineers). Raised wood floors (over crawl spaces) are becoming more and more popular as people are realizing they are available and do not like the idea of living upon concrete floors
These are very simple drawings which don’t really tell you how to build anything. In fact, once you get your plans, you may not take more than a quick glance at the elevation drawings, other than to be sure the building looks exactly the way you envision it. This includes where the doors and windows have been drawn. This is what counties like to see in deciding if the proposed new building is going to meet very specific guidelines in the area of aesthetics. Basically, does it “fit in” within the neighborhood, or is it going to stick out like a sore thumb? The community’s governing body decides what is “ok” or “not ok” for you to build.
