DEEP DIVE: Breaking Down Crosstree’s £330M Acquisition of The Argyll Club (London)
Is this what the next wave of office investing looks like?
When a premium flex platform trades hands below its former valuation, it grabs headlines. But when an institutional investor still steps up and buys it—real estate, operations and all—it says something else. This deal isn’t just about cap rates. It’s about conviction.

A £330M Trade—and a Market Marker
Crosstree Real Estate’s £330 million acquisition of The Argyll Club, the high-end flex office operator with 25 London locations, has quickly become one of the most watched office transactions of the year.
It’s not just the size. It’s what it represents.
The vendor, Alpine Grove (backed by Baupost), had originally sought £400M. That figure itself was already a step down from Argyll’s 2017 peak valuation of £475M.
So yes, this sale confirms what many in the market already suspect: valuations are adjusting. Buyers are pricing in higher cost of capital, operational exposure, and a more demanding return profile.
But pause for a moment.
Despite all of that — macro headwinds, post-COVID volatility, and tighter credit markets — an institutional investor still deployed hundreds of millions into a flex office platform with operational complexity and mixed tenure structures.
What does that tell us?
The New Flex Math: More Than Yield
We can debate the price. But the more interesting story might be the structure.
Argyll’s portfolio includes:
25 prime London office locations
10 freeholds, including trophy addresses like 33 St James’s Square and 78–79 Pall Mall
15 properties held under leases or long leasehold structures
A stabilised operational platform serving premium SME and enterprise customers
Barely a week after closing, Crosstree reportedly moved to sell one of Argyll’s crown jewels—33 St James’s Square—for north of £100M. That single disposal could return almost a third of their capital outlay.
That suggests something bigger:
this wasn’t a straight Propco acquisition, nor a pure Opco play. It’s a hybrid strategy — asset monetisation on one end, operational upside on the other.
And it raises a bigger question for all of us in the sector…
Are we entering a new phase where value isn’t just about bricks or brand,
but how intelligently the two are combined?
Why We Dug Deeper
At Brave Corp, we were curious…
What does the Argyll Club deal really tell us about the current market for operational real estate?
So we did a little digging.

Crosstree’s Acquisition of The Argyll Club
What Was Acquired
Crosstree acquired The Argyll Club platform in full, including:
25 prime flexible office locations across Central London
Freehold and lease structures
A stabilized brand and operating platform, not just real estate
This was a platform acquisition, not a one-off asset trade.
Purchase Price
Reported transaction value: ~£330 million
Vendor originally sought: ~£400 million (late 2024)
Previous peak valuation: £475 million (2017)
This reflects a ~17.5% discount from the vendor’s ask, and a ~30% drop from its prior peak valuation.
Estimated NOI at Sale
While Argyll’s exact NOI wasn’t disclosed, based on pricing and industry benchmarks:
Estimated platform-level NOI: ~£16–17 million per year
This reflects the net retained income after operating costs, not total rental income across the portfolio
Implied Yield (Blended Cap Rate)
Based on a £330M purchase price and ~£16.5M estimated NOI, the implied yield is ~5%
But this figure is not a traditional real estate cap rate
It seems to reflect a blended valuation across both the real estate assets and the operating company.
Some of the value is being capitalised based on freehold income potential, and some on retained earnings from the operational business. In that context, the “cap rate” is more of a proxy for blended enterprise value than a pure property yield.
Strategy in Play
Crosstree is already repositioning parts of the portfolio:
33 St James’s Square (Grade II-listed) is reportedly on the market for £100M+
By offloading a trophy freehold, Crosstree could recoup nearly a third of its capital outlay
That would effectively lower the basis on the remaining 24-location flex platform, increasing operational upside
This structure (monetising the real estate while investing in the operating business) is exactly the kind of thinking we believe will define the next generation of Space-as-a-Service investing.
The Bigger Picture
Crosstree’s acquisition isn’t just a pricing event. It’s a blueprint.
It shows that institutional capital is ready to back operational real estate, but only when underwriting is disciplined and structure is strategic.
It challenges operators, landlords, and investors to think more creatively about how to unlock value across both the Propco and Opco layers.
And it leaves us with a few important questions:
Is this the beginning of more strategic platform trades in the flex sector?
How should we be underwriting these businesses differently?
And who’s next?
We’ll be watching closely.
And as we build Brave’s own projects, we’ll be taking notes.
