Interiors

Wharton's argument is architectural before it is decorative: the principles of good architecture govern interiors no less than façades. A room is a problem in proportion before it is a problem in decoration. The decorative scheme that violates the room's underlying line cannot be rescued by ornament, however fine the ornament.

The wiki's working translation: a room earns its furnishings, not the reverse. To furnish a room before one has resolved its proportion is to dress a sentence before one has written it.

Wharton and Codman's central target is the Victorian interior: its accumulation of objects without regard for their scale, its competition of patterns and surfaces, its preference for richness of material over correctness of line. The result, in Wharton's account, is rooms that are expensive without being beautiful, full without being resolved, and impressive without being habitable.

The diagnosis is precise: the Victorian error is not poverty of taste but a mistaken understanding of what the interior is for. The interior exists to serve the person who inhabits it — its scale, its light, its arrangement should answer the life lived there. The decorator who begins with objects and works toward the room has inverted the logic.

I. Proportion before decoration. The room's structural character — its ceiling height, the ratio of window to wall, the relation of its length to its width — determines what the room can hold. This question must be settled before the question of furnishing can even be asked. The proportion of the room is its logic; decoration is the elaboration of that logic, not a substitute for it.

II. Scale is a discipline, not a preference. Every object introduced into a room must stand in the right relation to the room's proportions. A large room can carry large ornament; a small room cannot. The failure of scale cannot be corrected by the excellence of the individual piece. The right chair in the wrong scale is still wrong.

III. Use determines character. Each room has a function, and its decoration should serve that function rather than overriding it with general prettiness. The library is not the drawing room; the drawing room is not the bedroom. To decorate each as though the purpose were the same is to misunderstand the room and therefore to misunderstand the decoration.

IV. The plain room well proportioned outranks the elaborate room badly proportioned. Simplicity is not poverty. The plainest room, proportioned correctly and furnished for its use, will consistently outrank the elaborately decorated room whose proportions are wrong. Ornament is the reward for having got the proportion right, not a solution to having got it wrong.

• Roger Scruton, The Aesthetics of Architecture (1979) — philosophical parallel, making the same case from first principles

The principle of proportion before decoration is the interiors equivalent of the dress principle of the true silhouette before the accessory — True Fashion vs Passing Fashion. In both cases, the structural logic of the thing must be settled before decoration is asked to do any work. The accessory cannot save the wrongly cut dress; the ornament cannot save the wrongly proportioned room.

The continuity is not accidental. The discipline is one discipline applied to different material: understand the structure before attending to the decoration, and know what the thing is before deciding what to put on it or in it. Selection applies to rooms as readily as to wardrobes, and Restraint governs the well-set room as it governs the well-dressed woman.

The cross-domain concept of Restraint finds its clearest architectural expression in Wharton's argument. Her critique of the Victorian interior — its accumulation without regard for scale — is the interiors version of Dariaux's critique of the over-accessorised woman: an attempt to substitute accumulation for Judgement.

Proportion is the governing concept of the interior, as it is of the musical phrase and the well-set sentence.
