The Apthorp: A 1908 Courtyard Block, Now Condominium
The Apthorp is a prewar building an overseas buyer can actually purchase. The 1908 block by Clinton and Russell wraps an entire city block around a central courtyard, entered through arched carriage gates, and it is a condominium rather than a cooperative.
That combination — prewar rooms without a board approval vote — is rare enough to be worth a whole article. Let's take it.
1. What the Building Is

A full-block courtyard building, which is a form Manhattan produced only a handful of times. Apartments face either the street or the interior court, and the court is a genuinely quiet space in the middle of the Upper West Side.
It is a designated landmark, which governs exterior work and carries maintenance obligations the condominium funds. The carriage gates and the courtyard are the building's defining features and also its permanent responsibility.
Inside, the apartments are 1908 in origin: high ceilings, formal room sequences and proportions that new construction does not reproduce.

2. Why the Ownership Form Matters Here

Roughly three quarters of Manhattan's pre-1980 apartment stock is cooperative, and cooperative boards approve every purchaser, require verified financial disclosure and frequently restrict entity ownership and subletting.
A prewar condominium removes all of that. There is no board approval vote, only a right of first refusal that is almost never exercised, and non-resident and entity ownership are generally accepted.
For a buyer who wants prewar rooms and holds assets outside the United States, that makes buildings like this one a category of roughly a dozen candidates rather than several hundred.
Our foreign buyer guide explains why ownership form usually decides an international search before price is ever discussed.
3. The Diligence a 1908 Building Requires

Two layers. First the ordinary condominium review: audited financial statements, the reserve balance in dollars, assessment history and two years of board minutes. Those four documents describe the next decade better than any tour.
Then the questions specific to a landmark of this age: what is designated, what work is anticipated on the facade, the courtyard and the systems, and how the reserve study treats it.
A prewar building that assesses periodically and spends is in better condition than one that has not assessed in twenty years. Read the pattern rather than the absolute figure.
Our building diligence guide lists every document and what each one reveals when read carefully.
4. Buying Here as an Overseas Purchaser

Straightforward: no board approval vote, non-resident and entity ownership accepted, subletting governed by written building rules rather than by a board's discretion.
Mansion tax applies from $1 million on the whole price, reaching 2.25% between $5 and $10 million and 3.25% above $10 million, paid by the buyer at closing. Obtain common charges and property tax for the specific unit.
Settle ownership structure before contract; US estate tax reaches non-resident owners above a $60,000 exemption on US-situs assets. See our estate tax guide and buying from overseas guide.
Court-facing versus street-facing
The two are different products at the same address. Court apartments are quieter and more private with a shorter outlook; street apartments carry more light and more noise depending on which of the four frontages they occupy.
Ask for closed sales by exposure rather than for the building as a whole, and view at an hour when the street is actually busy. Both are public record and both are obtainable before you travel.
What prewar rooms are worth
Supply is fixed. No more prewar buildings will be constructed, the existing ones are protected, and the apartments in them cannot be multiplied — the same scarcity argument as park frontage, applied to a period.
Where such a building is also condominium, it serves a buyer pool that ordinary prewar stock cannot reach. That is a durable resale position rather than a temporary one.
Renovation in a landmark
Interior work in an apartment is generally a matter for the condominium's alteration agreement rather than for the landmarks authority, but anything affecting the exterior or a designated space is not.
Establish the alteration rules before purchase if renovation is part of the plan. In a building of this age the mechanical routes and the floor construction usually constrain a design more than the rules do.
Final Thoughts: The Rare Combination

Prewar rooms and a condominium deed rarely appear in the same building, and when they do the buildings serve a buyer that most of Manhattan's older stock simply cannot. What the age demands in return is real diligence on the capital position, because a 1908 structure has obligations that a 2019 tower does not. Do that work and this is one of the few genuinely open doors into prewar New York.

A note on financing for a buyer abroad. Foreign national mortgages require a larger deposit and a longer underwriting period than domestic ones, and lenders assess the building as well as the borrower — converted prewar buildings occasionally raise questions that new towers do not.
Confirm early that your lender is comfortable with the building itself. Discovering otherwise after a contract is signed is the single most expensive avoidable mistake in a cross-border purchase.
One further point on how few buildings share this profile. Prewar condominiums in Manhattan exist mainly because a building converted at a moment when the condominium form was chosen over the cooperative one, which was an unusual decision at the time and is not repeatable now.
That fixed supply is why apartments of this kind hold an audience that ordinary prewar stock cannot reach. The pool of international buyers who want prewar rooms is large, and the inventory available to them is not.
For a buyer weighing this against new construction, the trade is straightforward. A new tower offers current systems, predictable layouts and deeper amenity at a higher price per square foot. This offers rooms and a courtyard that cannot be built again, in a structure that will need capital work on a known schedule.

Schedule a ConsultationFrequently Asked Questions
Where is the Apthorp?
390 West End Avenue, filling the block between 78th and 79th Streets and Broadway and West End Avenue. The location is on [Google Maps](https://maps.google.com/?q=390+West+End+Avenue+New+York).
When was it built?
It was completed in 1908 to the design of Clinton and Russell, and is a designated landmark.
What makes the plan unusual?
It occupies an entire city block around a central courtyard, entered through arched carriage gates — a form that exists almost nowhere else in Manhattan.
Is it a co-op or a condominium?
It is a condominium. That is the significant fact for an international buyer, because prewar buildings of this quality are almost always cooperative.
Can a non-resident buy here?
Yes. As a condominium there is no board approval vote, and non-resident and entity ownership are generally accepted.
What should I confirm in a converted prewar building?
The reserve balance and capital plan for a 1908 structure, landmark obligations, assessment history, two years of board minutes, and the actual charges for the specific residence.
Do the apartments vary?
Considerably. A 1908 structure produces different ceiling heights, window positions and room proportions across the building, so the specific apartment matters far more than the building average.
