THE STARTING POINT
Can I explore the district without entering the houses?
Yes. This self-guided route uses public sidewalks to compare the historic rows. The buildings are private homes and other occupied residential properties. Stay outside gates, yards, stoops and vestibules, and use intersection crossings.
01 · Orient at 21st Street and 45th Avenue.
Open the interactive district map and the official LPC boundary map. The designation follows particular lots; the entire intersection and every adjoining parcel are not automatically included. On the north side, the documented groups begin at 21-09.
Look east along the roofline before concentrating on a door. Notice how building height, raised entrances and the spacing of openings produce a common rhythm even when the individual façades differ.

02 · 21-09–21-17: establish the vocabulary.
The first five-house group was recorded as an Italianate development of 1871–72. Compare its main wall, lower level, entrances and projecting cornice. These are useful parts to name when you later discuss a particular house with an inspector or architect.
The historic inventory then continues at 21-21. The absence of a separate 21-19 entry should not be turned into a claim that an unidentified property is excluded; follow the mapped lots and documented groups.
- Read the 21-09–21-17 profile.
- Keep your observations separate from conclusions about structural condition or lawful use.

03 · 21-21–21-29: look across as well as along.
At the north-side stone row, compare the entrances with the counterpart at 21-12–21-20 across the street. LPC recorded Westchester stone fronts and composition-stone balustrades and railings. At street level, concentrate on proportions, workmanship and how the stoop joins the façade.
Do not cross midblock for a closer view. The return leg brings you to the south row using intersection crossings. Read the north stone-row profile as you compare.
04 · 21-31–21-51: compare two brick groups.
Continue past 21-31–21-39, then 21-41–21-51. The latter group was described with a simpler Italianate treatment and narrow lots. A reported lot width is not the house’s usable interior width.
Look for differences in window surrounds, the way entrances meet the sidewalk and the continuity of the cornice. An altered entrance is a question for later records research; it does not reveal the building’s legal unit count.
05 · The mansard pair and the turn onto 23rd Street.
At 21-53–21-55, the roof becomes the defining feature. The report identifies Second Empire forms with slate mansards and dormers. Compare that silhouette with the cornice-led brick rows you have just passed.
Turn north onto the west-side sidewalk of 23rd Street. Follow the included 44-70–44-78 row from the corner toward 44-70. The shallow bow fronts and terra-cotta details give this short return its own expression. The district does not continue indefinitely north.

06 · Return to 45th Avenue: a different residential scale.
Retrace the short 23rd Street segment and use the intersection crossing to reach the south-side sidewalk. Begin westbound with 21-48 and 21-42–21-46. LPC described these as apartment-house forms dating to 1889.
Look at the height, angular bays, surface patterns and metal cornices. This part of the walk makes an important buyer distinction visible: the district is a residential ensemble, not an inventory of identical single-family townhouses.
07 · 21-36–21-40 and 21-34: a change in material and roofline.
Continue west past the gabled wood-house group and the individual frame house. Compare the roof shapes and the transitions between the main walls and lower levels.
Use the report’s material descriptions as historical context. You cannot diagnose concealed timber or identify a current cladding assembly from a sidewalk walk. Those questions belong in an address-specific investigation.
08 · Finish with the brick and stone rows.
At 21-22–21-32, look toward the cornices: LPC singled out Neo-Grec bracket details. Then finish at the south-side stone row, 21-12–21-20, and revisit the comparison you began across the avenue.
At the end of the circuit, write down three features you particularly liked, two practical questions about living with them, and one type of record you would want to see for a house you might buy. Bring that short list to Lauren when you are ready to discuss a search.
