DC's Row Homes Have a Grammar. Here Is How to Read It.

Most buyers look at a row home and see square footage, condition, and price. What they are not reading is the building itself: the cornice bracket, the fanlight, the bay window, the half-timbered gable. Each of those details is a timestamp. If you can read them, you know when the building was constructed, what the economy was doing, and which neighborhoods were being built out at the time. That context changes how you think about what you are buying.

Six styles account for most of the row homes in Washington. Federal and Italianate built Georgetown and the pre-Civil War city. Queen Anne and Second Empire built the Victorian expansion. Colonial Revival and Tudor built the early 20th century automobile suburbs. Here is what each one looks like and where you find it in the District.

Federal (1780s to 1820s)

Federal style is concentrated in Georgetown and Old Town Alexandria, which were the prosperous commercial centers of the original District. It is also visible in Annapolis and Baltimore. The identifying feature is the semicircular or elliptical fanlight above the front door. That rounded transom over the entrance is the clearest indicator a building is Federal rather than a later Colonial Revival copy.

Federal buildings also frequently have Palladian windows: a center window with a rounded top flanked by two shorter flat windows. Walk Georgetown and you will see that configuration repeated on block after block. The style is connected to the Adam brothers of England, who introduced classical references from Greek and Roman antiquity into domestic architecture. Swag ornaments above windows and engaged columns attached to exterior walls are Federal period details you would not find on an earlier Georgian house.

One practical note: Federal style is easy to confuse with Colonial Revival, which arrived 80 to 100 years later using some of the same motifs. If the building is in Georgetown or Alexandria, you can reasonably assume it is original Federal period construction. If it is in a neighborhood built out in the 1910s or 1920s, the fanlight and side panels around the door are Colonial Revival.

Italianate and the 1871 Bay Window Rule

Italianate was the dominant American style in the mid-19th century. Cities that boomed in the 1840s and 1850s are full of it. The identifying features are the heavy cornice at the roofline supported by individual decorative brackets, and the window hoods: the pronounced crowns above each window opening. If you see those two features together on a brick row home, the building is almost certainly Italianate.

There is a DC-specific rule worth knowing: if you see a bay window projecting from the facade, the building was constructed after 1871. That is when the District passed regulations permitting bay windows to extend up to four feet from the building line. Before 1871, they were not allowed. Bay windows are therefore a before-and-after marker. A building with them is post-1871. A building without them could be earlier.

Styles were not applied rigidly. The Frederick Douglass house in Anacostia is described by the National Park Service as both Greek Revival and Italianate simultaneously. That combination is not unusual. Builders and owners combined what was fashionable, what they could source, and what they could afford. Think of architectural style the way you think of fashion: people wanted to look current, and they layered accordingly.

Second Empire and the Mansard Roof

Second Empire is a variant of Italianate. It has the same cornice and brackets and the same heavy window hoods. The single distinguishing feature is the mansard roof: the steep, multi-sided Parisian roof form associated with Baron Haussmann's redesign of Paris under Napoleon III in the 1850s and 1860s. The style peaked in the United States in the 1870s.

The most prominent Second Empire building in Washington is the Old Executive Office Building next to the White House. At the residential scale, LeDroit Park has visible examples. The pattern is straightforward: take an Italianate row home and add a mansard roof. Remove the mansard roof from those LeDroit Park buildings and the facade beneath reads as Italianate.

Queen Anne and the Victorian Eclectic Period (1880s to 1900s)

Queen Anne is what most people mean when they say "Victorian house." It was the dominant American residential style from roughly 1880 through the early 1900s, and it was made possible by industrialization. Machine-made millwork, standardized lumber, mass-produced nails, and Sears and Montgomery Ward catalog sales enabled the layered complexity of a Queen Anne facade. The spindle work on the porch, the decorative woodwork in the gables, the mix of textures and materials: those were factory products ordered from a catalog and applied by local builders. A builder in 1896 could order everything needed to construct a house from a Sears catalog, receive roughly 30,000 parts by rail, and assemble the whole thing from 75 pages of instructions.

In Washington, Queen Anne buildings frequently combine Richardsonian Romanesque detailing. H.H. Richardson, considered alongside Frank Lloyd Wright and Louis Sullivan as one of the three greatest American architects of his era, defined the Romanesque Revival: rough-cut stone, heavy round arches, geometric or floral ornament carved around doorways and windows. You see that combination throughout Dupont Circle. The rough stone base or door surround on a house with a complex wooden porch and asymmetrical roofline is the Queen Anne-Romanesque hybrid that defines much of that neighborhood's character.

Queen Anne was widely demolished in the urban renewal campaigns of the 1950s and 1960s. What survived is now appreciated in ways it was not two generations ago. There is always something unexpected on a Queen Anne building, some combination of materials or ornament that no one would choose today, and that is the point. Cleveland Park has a cataloged Aladdin mail-order home near its northern end, one of a number of pre-assembled kit homes still standing in the District.

Colonial Revival and Tudor (1890s to 1940s)

By the 1910s and 1920s, Colonial Revival accounted for roughly 40 percent of new residential construction in the United States. It was not a nostalgic impulse confined to New England. The 1876 Centennial Exposition in Philadelphia and the Williamsburg restoration projects of the 1920s and 1930s reinforced its cultural authority nationally. Colonial Revival is symmetrical where Queen Anne is asymmetrical. The identifying feature is the door surround: a pediment supported by pilasters flanking the entry, often with a fanlight and sidelights, but in a more formal and heavier configuration than the original Federal period examples in Georgetown.

Tudor Revival arrived alongside Colonial Revival and was nearly as popular. By the 1920s, Tudor houses with half-timbered gables and steeply pitched roofs represented roughly a quarter of new residential construction in the country. In Washington, Foxhall Village is the concentrated example: almost every house in that neighborhood is Tudor Revival. Wherever automobile suburbs were being built in the 1910s through the 1930s, Tudor is what that era built.

Neither Colonial Revival nor Tudor has any particular historical connection to Washington. That is the point. By the early 20th century, geography had stopped determining architectural style. Buyers and developers were building what the pattern books and catalogs showed them: what the suburbs of their era said a house should look like. A Spanish Revival house on Nebraska Avenue, a Tudor house in Foxhall Village, a Colonial Revival house in Cleveland Park. None of those choices reference local history. They reference aspiration and fashion at a specific moment in time.

What This Tells You as a Buyer

The style of a building tells you when it was built. When it was built tells you what the neighborhood was when it was developed. That context is not trivia. Federal and Italianate buildings in Georgetown are there because that part of the city was prosperous and commercially connected from the 1790s through the 1860s. Tudor and Colonial Revival in Foxhall Village and Cleveland Park are there because those neighborhoods were platted as automobile suburbs in the 1910s through the 1930s, at a moment when the city was expanding northwest along ridge lines and streetcar routes.

Understanding style also tells you what to look for in a specific building. A bay window on a Georgetown row home means the house was modified or expanded after 1871. A mansard roof on a LeDroit Park house means Second Empire, not Italianate, and places the construction firmly in the 1870s. A Queen Anne porch added to a Federal-period house means someone in the 1880s or 1890s wanted to look current and had access to a Sears catalog. Buildings accumulate their history on their facades. You just have to know how to read it.

The buyers who understand this are not reading buildings for trivia. They are reading buildings for context. Context does not change the price. But it does change the quality of the reasoning behind the price.
