Part 5 — Building Sections | Sheet by Sheet

  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.

Part 2 — Lot Sets: Same House, Different Story | Blueprint to Build

Same house plan. Fifty different lots. And somehow every single one needs something different.

The lot set takes the master and adapts it for each individual site : width, depth, slope, orientation, garage entry. It looks routine. It isn't.


What actually changes:
• Site plan — setbacks, lot lines, driveway
• Grading and drainage — critical on slopes
• Foundation — slab, crawl, or basement
• Garage orientation — front, side, or court load
• Elevation selection — which façade fits this lot


The mistake that costs builders:
Treating lot sets as copy-paste. A master dropped onto a sloped lot without grading coordination means foundation conflicts mid-framing. A flipped garage without checking the floor plan means a mirrored layout that doesn't work.

The fix: Work through each lot methodically. Site plan first. Foundation next. Options last. Every sheet checked against the master before it goes out.
