1. The Victorian Rowhouse

The Victorian rowhouse is the defining residential form of Capitol Hill and much of central DC. Built primarily in the decades following the Civil War, these homes are identifiable by their bay windows, turrets, ornate brickwork, and decorative cornices. The "bay-front" Victorian is a particularly significant variant — the projecting bay adds usable square footage to the living room and master suite that flat-front homes of the same era lack, which is reflected in price-per-square-foot comparisons.

Victorian rowhouses are also the style most likely to include an English basement — a separate ground-floor entrance that historically housed domestic staff and today functions as a rentable unit. This feature is one of the most consequential architectural details a DC buyer can look for.

Where to find them: Capitol Hill, Logan Circle, Columbia Heights, Shaw, Trinidad.

2. The Federal Rowhouse

The Federal rowhouse is the oldest residential form in Washington DC, with surviving examples in Georgetown and Capitol Hill dating to the late 18th and early 19th centuries. These homes are defined by their restraint: flat brick façades, understated symmetry, small windows proportioned to the era's glass technology, and fanlight transoms over the front door. They reflect the early American design philosophy of classical order applied at domestic scale.

Federal rowhouses are generally smaller than Victorians — narrower lots, lower ceilings, more compact room layouts — but their extreme age and concentration in historically significant locations makes them among the most coveted properties in the city. Georgetown's Federal stock in particular is treated as a scarcity asset by the market.

Where to find them: Georgetown, Capitol Hill (west blocks), Old City, Old Town Alexandria.

3. The Craftsman Bungalow

The Craftsman bungalow arrived in DC with the expansion of the city's streetcar lines in the early 20th century. One-and-a-half stories with wide front porches, low-pitched roofs, exposed rafter tails, and an emphasis on natural materials — wood, stone, and brick used honestly rather than decoratively — these homes represent a deliberate shift away from the ornamentation of the Victorian era toward simplicity and craftsmanship.

They are concentrated in what were once DC's streetcar suburbs: Del Ray and Takoma Park in Maryland, Petworth and Brookland in DC proper. These neighborhoods have seen strong appreciation as buyers trade vertical rowhome living for the horizontal porch culture and larger lots that bungalows offer.

Where to find them: Del Ray, Takoma Park, Petworth, Brookland, Brightwood.

4. The Tudor Revival

Tudor Revival homes arrived in DC's upper northwest neighborhoods during the interwar period, when buyers with larger budgets sought homes that felt more substantial and private than the urban rowhouse. They are identifiable by steep pitched roofs, stucco or half-timbered upper stories, exposed timber detailing, and decorative chimney stacks. These homes typically sit on larger lots than rowhouses, often with garage parking and meaningful private green space — features that are genuinely scarce in the District.

Where to find them: Foxhall, Mount Pleasant, Forest Hills, Spring Valley, AU Park.

5. The Colonial Revival

Colonial Revival homes draw on early American architectural tradition — symmetrical brick façades, shuttered windows, center-hall plans, and classical porticos — reinterpreted for the late 19th and early 20th century suburban buyer. They are more spacious than Federal rowhouses and more formally composed than Victorians, appealing to buyers who want a traditional aesthetic without the ornamental complexity of Victorian design.

In DC, Colonial Revival homes are concentrated in the city's northwest quadrant and immediately adjacent Maryland suburbs, where larger lots supported detached single-family construction.

Where to find them: Chevy Chase, AU Park, Palisades, Wesley Heights, Bethesda.

6. The Italianate Rowhouse

Italianate rowhouses brought decorative flair to DC's residential streetscapes in the decades between the Federal and Victorian eras. They are identifiable by bracketed cornices, tall arched windows, decorative ironwork, and low-pitched roofs with wide overhanging eaves. In DC they appear most often as attached rowhouses rather than freestanding villas, giving the style a distinctly urban character that fits comfortably within Capitol Hill's mixed architectural landscape.

Where to find them: Capitol Hill, Shaw, H Street corridor, LeDroit Park.

7. The Mid-Century Modern

Mid-Century Modern homes are the rarest residential style in DC proper. Built during the postwar decades, they are defined by flat or low-pitched roofs, large expanses of glass, open floor plans that dissolve the separation between living, dining, and kitchen spaces, and minimal exterior ornamentation. They reflect a confidence in modernism that was more fully expressed in DC's suburbs than in the city itself, where the rowhouse tradition remained dominant.

Where they exist — McLean Gardens, Friendship Heights, and pockets along the Maryland border — they command a premium among buyers specifically seeking open-plan living that is difficult to achieve through renovation of a Victorian or Federal rowhouse.

Where to find them: McLean Gardens, Friendship Heights, Bethesda border, parts of Silver Spring.
