From 1665 onwards the popularity of the pilaster facade started
to decline. Between 1665 and 1700 the Classicist style became even more
austere. We speak of the ‘flat style’. Architects reduced decorative
elements to an absolute minimum, dispensing with pilasters altogether,
or using them only to emphasise the entrances of their buildings. The
final stage of Dutch Classicism relies on a rhythmical approach to the
arrangement of the various parts of the facade, on the inherent
expressiveness of unadorned surfaces and well-cut window frames to
achieve an effect of elegant simplicity and dignity. Decoration is
relegated to the central bay, the entrance and the middle section of the
cornice. The emphasis is placed on the central axis, which becomes more
and more pronounced outside as well as inside the building. Adriaan
Dortsman (1636-1682) is commonly considered the champion of the flat
style, but it was Philips Vingboons who paved the way in 1638 when he
designed Herengracht 168 and dispensed with pilasters for the first
time. Vingboons was versatile enough to adjust his designs to the new
era. His design for Herengracht 412 (1664-1667) is basically a pilaster
facade. However, he used pilasters only to articulate the middle
ressault, leaving the adjacent bays unadorned. Subsequently, only flat
facades were built. An important factor in the rise of the flat style
was the increased building activity which resulted from the 1663 urban
expansion plan. The ring of canals was expanded beyond the Leidsegracht,
completing the crescent shape of the Amsterdam City centre. The new
residential areas catered for the wealthy urban elite of the time, i.e.
rich citizens who could afford large double mansions designed by the
top-class architects of the time. Among the mansions designed by
Vingboons in the flat style are: Herengracht 450 (1663) commissioned by
Joseph Deutz; Keizersgracht 577 (1665) commissioned by Isaac Nijs and
Herengracht 466 (The Eagle, 1669) owned by Jeronimus Haase.

Herengracht 462 (1672)
After 1670 the younger generation of architects, with Adriaan
Dortsman and Elias Bouman in the lead, continued to develop the new flat
style. The facade of Herengracht 450 illustrates the typical Dortsman
approach with its flat blocks of stone and pronounced joints which
create the impression of a stylised form of rustication, while the
corners are articulated by pilaster strips. More Dortsman facades:
Herengracht 619 (1667-1669); Keizersgracht 672-674 (Van Raey Houses,
1671); Herengracht 462 (Sweedenrijk, Empire of Sweden, 1672); Amstel 216
(1672); Keizersgracht 730-734 (1672); the block which includes
Herengracht 621-629 and Amstel 208-212 (1673). Keizersgracht 604 (Int
Derde Vredejaar, Third Peaceyear, 1670), a flat brick facade, is also
attributed to Dortsman.
The flat style is eminently suited to large double mansions, but
the narrow single houses were affected by the new fashion as well. The
neck-gable lost its pilasters and became a flat facade with sandstone
ornaments relegated to the top gable.
Herengracht 508-510 (1688)
Often the exuberant crolls which adorn the neck-gables at this
time seem to compensate for the lack of decoration elsewhere. Elaborate
sculptures of human figures and animals were often placed on either side
of the neck. Examples: Herengracht 390-392 (1665), Herengracht 504-506
(1670), Herengracht 508-510 (1685).
The flat style neck-gable finally leads to the bell-shaped gable,
when the area commonly reserved for the crolls was incorporated into the
shape of the neck. This effect was achieved by using brick only and
dispensing with the sandstone elements, e.g. Keizersgracht 716 (1671).
