  The roof plan is the most underestimated sheet in any residential set. It looks simple from above — just a bunch of lines and arrows.  But those lines represent ridges, valleys, hips, and overhangs that the framing crew has to translate into three dimensions. Get the roof plan wrong and the framing crew gets it wrong with you. What it shows: Ridge lines, hip lines, and valley lines Roof slopes and pitch callouts Overhangs and eave dimensions Crickets and saddles at chimneys and vertical walls Roofing material and underlayment notes Skylight and roof penetration locations Downspout and gutter locations Key terms builders need to know: Ridge — the highest horizontal line where two roof slopes meet at the top. Valley — where two roof slopes meet going inward. Water runs here — critical to get right for drainage. Hip — a sloping line where two roof planes meet at an outside corner. Cricket — a small raised s...

  Every builder has a story about a detail nobody read until it was too late. Wall sections and details are the most technical sheets in any residential set. They're also the ones contractors reach for most on site — when something doesn't fit, when a material transition isn't clear, when a connection needs verification. What it shows: Full wall assembly from foundation to roof Exterior cladding, sheathing, framing, insulation, interior finish Waterproofing and moisture barrier locations Window and door head, sill, and jamb conditions Floor to wall connections Roof to wall connections and eave details Flashing locations and types Why details matter: A wall section tells the contractor how the wall is built. A window jamb detail tells them exactly how the window sits in the opening — setback, flashing, sill slope, interior trim clearance. Without the detail, the contractor makes a judgment call. Sometimes that...

  Plans show you the layout. Elevations show you the faces. But neither tells you what's happening inside the walls. That's what sections are for. A building section cuts straight through the house — vertically — and exposes everything plans and elevations leave hidden. It's the sheet that answers the questions contractors ask most: how high is that ceiling? Where does the stair land? What's the structural depth at that beam? What it shows: Interior ceiling heights — room by room Stair geometry — rise, run, headroom clearance Structural member depths — beams, headers, joists Insulation layers and wall assembly thickness Roof structure and attic conditions Floor to floor heights on multi-storey homes Relationship between indoor finished floor and outdoor grade Types of sections: Building section — cuts through the full width or length of the house. Shows the big picture — overall height, stair relationshi...

  Four sides. One house. And every single one needs to be documented. Most permit reviewers look at elevations before they look at plans. Contractors use them to frame openings, apply cladding, and set window heights. HOA reviewers use them to check design compliance. If any elevation is wrong — the ripple runs through the entire build. What it shows: All four facades — front, rear, left, right Exterior finish materials and transitions Window and door locations and heights Roof pitch and overhang dimensions Finished floor and finished grade lines Building height for permit compliance Elevation option differences — Craftsman, Farmhouse, Traditional Why all four sides matter: Builders often focus on the front elevation — it sells the house. But the rear elevation is what gets framed. The side elevations show gable heights, window placements, and cladding transitions that contractors work from directly. A missing rear e...

  It's the most recognizable sheet in any set. It's also the most misread. A floor plan isn't just a room layout. For a builder, it's a coordination document — dimensions, structure, openings, and clearances all on one sheet. Miss what it's actually telling you and problems show up in framing. What it shows: Room dimensions and overall building dimensions Wall locations — exterior, interior, and load-bearing Door locations, sizes, and swing directions Window locations and sizes Stair layout and direction Bathroom fixture locations Structural columns and beams Notes referencing sections and details What builders actually read: Dimensions first. Overall building dimensions, then room dimensions, then critical clearances. Any dimension that doesn't add up is a problem waiting to happen on site. Load-bearing walls. Not always labeled but identifiable by their position relative to structure above and below. A contractor who...
