Three Design Paradigms: 1 Traditional Style , Sustainability2, Affordability3 Story Boards
1.
Typical 5-layer crosslaminated timber panel Walls, floors, ceilings
Left -- traditional style paradigm. 2. Timber replaces steel/concrete. Comparable strength, nontoxic. 3. Prefab for affordability.
Process Our class project’s design goal was to first to cenceptualize a box kite design, then through various iterations, to transform it into a model with architectural attributes. My genesis sequence:
1
2
4
3
Model derived from “2”.
Concept drawing: hollow, rectangular box kite-like shape. Materials: card stock, clear plasic film Clapboard siding-- not taditional enough!
Drawing: now both ends tapered mansards. X-braced center section, same card stock. Envisioned “solar panel” mansards, all framing balsa.
New plan dwg.: now five rotated boxes, top, bottom open. Tensile “wires” envisioned as gray thread simulation of steel, same balsa frame.
5
Class now directed to select an inspirational object or theme for model development. Above “Lattice House”, Jammu, India aligns closest to my “sustainability” theme, with elements of “traditional”. Exterior material: red cedar.
6 New plan drawing: in SketchUp for more 3D-like appearance.

Model derived from 6-8. Box kite-like, simulating CLT

Full-scale (18” x 24”) model. All balsa frame, straight-pin joints. Balsa and card stock proved insufficient in strength ….
12 Final model: now draped in more forgiving fabric and framed in basswood. Joints now wrapped in thread, coated in glue.
traditional, sustainable, affordable!
