If your ready to stand with your name behind what your saying then we can decide if we want to believe you or not.
The clear words in Kuntros Rabeinu Shebbavel speak for them self.
There are many other answers in the tshuro from fisher after the Sicha you mention that clearly show the rebbe wanted more than expanding the bathrooms…
Last but not least Rabbi Krinsky has spoken openly at the last kinus Hashluchim about this. Enough said

Please don’t make these mistakes:

“Saying to disregard a taped public sicha of the Rebbe because the Rebbe didn’t edit it”

“The website clearly writes … that the actual shul of the Rebbe will be changed”

And “The renderings… unconscionable, and flies in the face of the Rebbe’s many horaos” not sure why you are reading a negative hot-take groundlessly. You read some of the site, why not read the rest of the site. See if you’re able to get the picture without cherry picking

Not to expand the shul ?
Quote: “The Rebbe said no” ?
Quote: “Expansion… the Rebbe didn’t allow” ?

I think you might be extrapolating and conflating things. Re-read all the toichen and make a clear diagram of what the Rebbe exactly did and didn’t say, and where you might be doing a bit of “Chavo’s mistake”

The renderings show the other structures higher than 770 – against a written instruction of the Rebbe.
The price tags discussed – are way, way above what the Rebbe approved.
The website clearly writes that not only will an additional wing be added to 770 [which one can argue is absolutely necessary today simply for reasons of pikuach nefesh mamosh] – but that the actual shul of the Rebbe will be changed. That’s unconscionable, and flies in the face of the Rebbe’s many horaos.
If the plan was:
Capital improvement of 770,
An expansion of additional space,
Within the budget that the Rebbe approved,
Within the parameters that the Rebbe laid out, such as not building higher than 770,
Without changing the Rebbe or the Frierdiker Rebbe’s shul,
As well as the Rebbe’s many other parameters,
you have my blessing, you have of course the Rebbe’s blessing, and it’s a very worthwhile cause.
Just be mindful of those points.
You are promoting specific plan ideas that are contrary to written horaos of the Rebbe.
Saying to disregard a taped public sicha of the Rebbe because the Rebbe didn’t edit it, is silly.
Obviously the 2 sichos are not contradictory, as explained above.

Very good question.
The Rebbe was magiha the kuntres.
The answer is obvious.
One cannot cherry pick.
One needs to look at all the Rebbe’s horaos on a subject, which maybe multi faceted, and then understand his position.
You could as a better question:
An expansion actually did take place in those years.
Answer to both questions:
The Rebbe didn’t allow a change to the shul. They had major ideas to expand to Union St, to raise the ceiling of the offices, to install skylights, to change the design of the room, etc etc
The Rebbe allowed bathrooms to be built, and he allowed necessary renovations and upgrades.
Maintenance and upgrades are necessary.
Otherwise a building collapses.
See for example 770’s frequent flooding.
See for example issue of cleanliness, particularly in the womens section
See for example other capital issues, such as a/c replacement [today can cost a million dollars] or roof issues.
But an expansion of property, to the Rebbe’s shul, he didn’t allow.

Don’t take my word for it.
Look up all the Rebbe’s written letters on the subject.
For example the Rebbe wrote (it’s been printed, but this is from memory:
תוכנית שמסתכמת בעשר מיליון דולר מובן שמופרך לגמרי. וצריך להיות פחות ממיליון דולר וכל הממעט בזה הרי זה משובח
People who were involved then, are still alive, besides the one who you mentioned, recall the Rebbe putting the brakes.
Rabbi Krinsky also said that the Rebbe was opposed to it, “but it was due to a reason, and the reason no longer applies”, not sure what that means.
Learn the Hoshana Rabo sicha
It doesn’t negate Kuntres Rabeinu at all.
If you learn Kuntres Rabinu, and the other wrtitten tzetlach and sichos – they are not contradictory.

Expand770.com states clearly what our mission is, to promote and encourage the expansion of 770.
The actual expansion is in the hands of Aguch and Merkos, your accusations of us not following the Rebbe’s horaos are false and misplaced.

My response is that we are just promoting and encouraging the expansion. The ones who were put in charge by the Rebbe are the ones who will make the expansion and I’m sure that they are well aware of all the Rebbe’s detailed instructions.

As far as Leil Hoshaana Rabba 5749 (which happens to be unedited by the Rebbe, contrary to kuntres beis rabeinu shebibovel, which was edited and published 3 years after that sicha), it is well known that before that Hoshaana Rabba there was a meeting where ppl told the Rebbe that they have their own ideas of how expansion should happen, and this is even in the words of the sicha (“בא כל א’ עם סברא משלו, וכשפלוני אומר באופן כך, אומר, שהוא יבנה בנין יותר גדול”), and the Rebbe was making it clear that no one should think that they understand better, because the only one who is in charge is the Rebbe.

With that said, the Rebbe said and edited and published in the kuntres beis rabeinu that there must be expansion, and that everyone should get involved in helping physically and financially (וכל המרבה הרי זה” “משובח).

We’ve waited much too long!

“Why not preserve 770 as it looked before Gimmel Tammuz?

The true way of preserving that original look is to constantly expand 770, because that’s actually the look that 770 always had. Would you entertain the thought of preserving the Chabad Shluchim to the amount of Shluchim we had before Gimmel Tammuz?! The Rebbe’s vision is Uforatzta! Expand!!

Let’s preserve that vision!”

Look up that sicha, as well as the Rebbe’s written letters [for example, the sharp letter about knocking a nail! for the sukka into the building of 770] – and see if it’s matching the horao’s.

There were many, many Horaos from the Rebbe on this subject in those years – all in Ksav Yad Kodesh – which severely limited the scope of the project – and the current backers are not following them.

Various points throughout the sicha on this topic.

The Rebbe says clearly that Shnas Habinyan excludes 770, and that a change to 770 will reduce the kedusha of the Rebbe’s shul.

There are many Kisvei Yad on the topic.

There were also meetings with the Rebbe and the Vaad Habinyon, where the Rebbe laid down the law pretty strictly.
