I've read both drawings. Key printed dimensions: overall 26'-0" × 24'-0", porch 26'-0" × 6'-0", and six labeled rooms. Building the shell now — every inch value is converted exactly (×25.4) to millimetres inside the Replicad code.
The 3D model is built from the dimensions on the plan and is now compiling in your browser (it finishes after this turn — the card's breadcrumb will confirm the measured size). Here is every dimension I read, with assumptions flagged.
Dimensions read from the drawing
| Element | Width | Depth | Where it came from |
|---|
| House, overall | 26'-0" (312 in) | 24'-0" (288 in) | printed across the top, down the right side, and in the catalog "The Size: 26 ft. x 24 ft." |
| Front porch | 26'-0" (312 in) | 6'-0" (72 in) | printed on the porch |
| Chamber (rear-left) | 9'-0" (108 in) | 10'-9" (129 in) | printed in the room |
| Chamber (front-left) | 10'-0" (120 in) | 9'-3" (111 in) | printed in the room |
| Living room (front-right) | 14'-6" (174 in) | 11'-3" (135 in) | printed in the room |
| Kitchen (rear-right) | 8'-6" (102 in) | 11'-3" (135 in) | printed in the room |
| Bath | 6'-6" × 5'-3" | — | printed in the room |
| Pantry | not dimensioned | — | labeled only |
| Hall | not dimensioned | — | labeled only (drawn as an octagon) |
| Closets ("CLO" ×2) | not dimensioned | — | labeled only |
Placement correction: the 9'-0" × 10'-9" chamber is the rear-left room, not front-left — the porch marks the front, so the 10'-0" × 9'-3" chamber (10 ft = 120 in, the wider of the two) is the front-left one and the 9'-0" room sits at the back-left. I placed them that way.
Values I had to assume
| Assumption | Value used |
|---|
| Bath orientation (label order ambiguous) | 5'-3" wide (63 in) × 6'-6" deep (78 in) |
| Pantry clear width | 16 in (narrow, as drawn), full-width opening rather than a 32-in door |
| Hall (octagon in plan) | simplified to an L-shaped circulation space; boundaries set by the rooms around it |
| Closets | 2 closets, 38 in wide × 24 in deep, opening south into the front chamber |
| Living-room width vs. walls | modeled 14'-8" (176 in) so 10'-0" + 4-in partition + living room fit the 26-ft interior; the plan's 14'-6" leaves a ~2-in rounding gap |
| Window openings | 36 in wide (given) × 48 in tall, sill 36 in above floor — only the width is on the plan |
| Door/window positions along walls | not dimensioned on the plan; placed at plausible bay centers |
| Cellar stair ("DOWN", rear-right) | omitted — an addition outside the 26×24 rectangle, not part of the requested footprint |
Interior clear heights: walls 96 in on a 4-in slab; partitions 4 in; exterior walls 6 in; porch slab 8 in with its top flush to the house floor.
What to check on the card
When the build finishes, confirm the overall measured extents read about 312 × 288 in in plan (with the porch adding 72 in toward −Y) and 100 in total height. If the breadcrumb says build=FAILED, tell me the error line and I'll correct and resubmit.
AutoCAD download: on the model card use STEP — it carries the exact geometry and opens directly in AutoCAD, Fusion, SolidWorks or FreeCAD. The same card also offers STL (3D printing) and SVG plan/elevation sheets with overall dimensions.
Two things I can tighten on request: (1) I can model the octagonal hall and the CLO closets closer to the drawing if you confirm their sizes, and (2) I can add the rear cellar-stair addition as a separate body.
