Pattern Five Parts in Proportion : Cluster of Forms

Jeffrey Limerick's house in Boulder, Colorado, steps back from the street and presents a well-orchestrated assembly of building blocks, roof forms, and textures in the dignified manner of many traditional Boulder homes.

The house is an example of informal, asymmetric balance and proportion. The two main front masses of the house remain in balance because they each have a center a large, high window centered under a symmetrical portion of roof. They share similar materials, colors, and textures. They share one roof surface and are, therefore, actually part of a larger entity.

This balance can be better understood from a side view of the house, which shows overall form as an assembly of similar gable-roofed volumes, intersecting at right angles, stepping down from the tallest to the lowest front window bay on the street.

Good proportions on the outside grow directly out of the plan. Each of the rooms, both inside and out, has a fat rectangular shape. The rooms are then organized to form two larger halves, each shifted relative to each other to form the entry in the front and the deck in the back. The resulting plan, and the resulting volume of the house, is composed of the same bulky rectangular proportions. This unity of shape is a hallmark of good proportion.

Good balance and proportion don't require symmetry. The house achieves its harmony through repeated use of similarly shaped forms assembled into a roughly balanced whole.

Rooms don't need to be crisp rectangles. They can be irregular with straight or rounded wall sections, but generally they should be compact, oblong, and not too skinny.

The Potato-Shaped Room

Using roughly similar shapes for the rooms gives unity to a house plan. But what is the shape of a well-proportioned room? We tell our students (and remind ourselves!) that rooms should be shaped more like a potato than a carrot relatively compact and oblong not long and skinny. Generally, a room should be a little longer than wide, but not by much. This shape is flexible, naturally holding a single social gathering as well as two smaller ones. When we begin a design, we sketch rooms as fuzzy tuber-shaped blobs.

Andrea Palladio, the great 16th-century Italian architect, specified precise room proportions derived from the musical harmonies produced by specific lengths of vibrating strings or pipes full of oscillating air.

But he also admitted that these ideal proportions could be modified as needed to fit the rooms into their places in the building. In effect, he advised that a room never be narrower than half its length and that the height never be less than the width. This produces rooms that are compact and chubby in volume much like a potato.
