Only operations that are well-established, high turnover, standardised or highly subsidized can afford, commonly, to carry the costs of new construction. Chain stores, chain restaurants and banks can go into new construction. But neighbourhood bars, foreign restaurants and pawn shops go into other buildings. Supermarkets and shoe stores often go into new buildings, good bookstores, and antique dealers seldom do. Well subsidized opera and art museums often go into new buildings – studios, galleries, stores for musical instruments and art supplies, backrooms where the low earning power of a seat and table can absorb uneconomic discussion – these go into old buildings.
Old ideas can sometime use new buildings. New ideas must come from old buildings.
Jane Jacobs, Death and Life of Great American Cities
