Field Guide · Reading Manhattan
A building tells you how it was made, if you know how to listen.
Thirty terms, each drawn plainly, for reading a Manhattan building from the sidewalk to the radiator. Tap any plate for the full entry. I'd keep it open on your phone at the next open house.
Educational onlyGeneral information about architecture and buildings. Not legal, financial or engineering advice. Every building is its own case, so confirm specifics with a qualified professional.
The Face
The street side of a building is its handshake. It tells you when it was built, how it was built and, with a little squinting, how it has been kept.
A cornice is lovely and heavy, and it hangs over the sidewalk. Buildings taller than six stories are inspected under the city's facade program every five years, so its condition can turn up in the building's repair budget.
Cracks fanning out from the corner of a window are often a rusting steel lintel expanding inside the wall. It's a routine repair, though not a cheap one when it runs across a whole facade.
The parlor floor at the top of the stoop usually has the tallest ceilings and the best windows in the house. The stoop itself is masonry outdoors in a New York winter, and it ages accordingly.
A setback is often where a private terrace comes from. Ask who maintains the roofing underneath it, because the answer varies by building and by document.
Pilasters are a tell. They suggest a building that spent money on its face, which says something, if not everything, about how it was built.
The Bones
You never see most of this once the paint goes on. You feel it, though, in where the walls can move and how the floor answers your step.
In a column-framed building, walls between them can often move, which is good news for renovation. A column in the middle of a living room cannot, and it rarely appears on the floor plan as prominently as it does in person.
The slab is shared structure. Drilling through it to move a drain or add a pipe usually needs the building's blessing and an engineer's review.
Each has a personality. Concrete flat slabs tend to mean lower ceilings with few beams. Steel with masonry tends to mean thick walls and plaster. Neither is better in the abstract. It depends on how you live.
The Rooms
Trim and proportion are where an apartment shows its manners. Some of it is original. Some of it arrived last spring from a catalog.
Original plaster crown is hard to fake and expensive to replace. When it survives intact, it suggests a renovation history that was respectful, which tends to be good news elsewhere too.
Real wood paneling adds warmth and some resale charm. Applied trim imitating it adds charm too, just less of the warmth. Tap it gently and you'll usually know.
Coffers need height to look right. Under a low ceiling they press down, so judge them by how the room feels, not by the photograph.
An enfilade makes an apartment feel larger and more formal than its square footage. It also means some rooms are passed through, a small thing until you want to close a door.
Lovely between a living room and a library. If a vintage pocket door sticks, the repair often means opening the wall, so give them a slow test slide.
The Families
Manhattan buildings come in recognizable families, each with its own habits. Knowing the family is half of knowing the apartment.
Prewar suggests thick walls, plaster and generous rooms. Co-op means a board reviews buyers and renovation plans. Both facts shape the apartment as much as the floor plan does.
Often the most square footage for the money, with efficient layouts and lower ceilings. The trade is a little character for a lot of practicality, which some people find a bargain.
The Plumbing of Comfort
Heat, cooling, water and laundry. Unglamorous, permanent, and the part of a home you notice every single day.
An existing sleeve is quietly valuable. Cutting a new one through a facade usually needs board approval, and often more paperwork if the building is landmarked.
PTACs give each room its own control, and each owner its own electric bill. They can also be noisier than central systems, so turn one on during a visit.
Kitchens and baths cluster near risers. Many buildings won't let a wet room move over a neighbor's dry one, which quietly limits how far a renovation can wander.
In-unit laundry is rarely just a matter of buying machines. Many co-ops restrict or prohibit it, and where it's allowed, venting and the board's rules decide what you can install.
You inherit the building's heat, and you don't control it much. City rules require heat from October through May, and old steam systems can run a little enthusiastic. Those clanks are part of the bargain.
Coast to Coast
Some things you only meet on one coast. A cedar tank on a Tribeca roof, a bungalow in Pasadena. Each is local knowledge, and each tends to surface in the paperwork sooner or later.
The tank is the building's plumbing in plain sight. City rules require it to be inspected and cleaned every year, and replacing one eventually lands in the building's budget. A charming silhouette, and a line item.
It looks like a balcony and isn't one. The law expects it to stay clear, so no planters or chairs, and any window gate onto it has to be an approved type. Count it as a view of the street, not square footage.
Some California cities, Los Angeles and San Francisco among them, have required many of these buildings to be retrofitted. I'd want to know whether the work is done, permitted and paid for, since that answer shapes both safety and the building's finances.
Original tile, ironwork and plaster are the point, and they are hard to replace in kind. Clay roofs last a long time but tiles crack when walked on, and stucco shows every settlement. Look closely, and with affection.
The built-ins, wood trim and old-growth lumber are the inheritance. So is a century of wiring, plumbing and foundation work, done well or otherwise. An older California house can also call for seismic work, so it's worth asking what has been done.
An ADU can house a parent, an office or a tenant, and that flexibility has real value. What matters most is whether it was permitted. A permitted ADU is part of the property. An unpermitted one can be a question mark.
Learn the words and the walk-through changes. You stop asking if you like a place and start noticing what it's made of, which tends to be the better question.
