building
205
Structure Follows Social Spaces
Let the structural plan emerge from the social plan, not the reverse.
construction

construction
207
Good Materials
Choose materials that age well, can be worked by hand, and can be repaired in place.
construction
208
Gradual Stiffening
Build loose, then stiffen as you know the building is right — don't lock in early.

construction

construction
220

construction
227
Column Connection
Columns connect to what they carry through a visible capital — not a sharp line.
construction

Dormers turn an attic into a room.
construction
232
Roof Caps

construction
234
Lapped Outside Walls
Outer walls lap and weather in layers, not flush cladding.
construction
235
Soft Inside Walls
Inside walls are best when slightly soft to the touch — plaster, wood, not hard gypsum.
construction
236
Windows Which Open Wide
Windows should open fully — at least half their area, not a small hopper.
construction
237
Solid Doors with Glass
Main doors are solid with a pane of glass — you can see and still shut.
construction
238
Filtered Light
Filter direct sun through leaves, lattice, or trellis; raw sun is blinding.
construction
239
Small Panes
Break large panes into small ones — the light pattern is livelier and scale is human.
construction
240
Half-Inch Trim
Trim elements at half-inch increments — thick enough to hold a shadow line.
construction

construction
247
Paving with Cracks Between the Stones
Leave cracks in paving for grass and insects — a living floor.
construction

Soft Tile and Brick
Use soft, hand-made tile and brick; machine-hard surfaces never acquire life.
construction
249
Ornament
Ornament where edges meet — not pasted on, but at real joints.
construction
250
Warm Colors
Warm colors on indoor surfaces — cool colors only accent them.
construction
251
Different Chairs
Never furnish with identical chairs — every chair should be itself.
construction
