A Barcelona coworking site just proved a point the flex industry has been making all year: give corporate tenants a private, serviced office instead of an open-plan desk, and they’ll take it almost as fast as you can build it.
Spanish flexible workspace brand L’illa & Co. has added a third floor to its site inside the L’illa Diagonal complex, one of Barcelona’s busiest mixed-use business addresses on Avinguda Diagonal. The new floor, branded “A Mida” (“Made to Measure” in Catalan), is dedicated entirely to managed offices, and according to the operator, it was already more than 80% occupied on its very first day of operation.
It’s a small, single-location story on paper. But it’s a useful snapshot of where a big chunk of the flexible workspace market is heading in 2026: away from pure coworking and toward private, serviced offices that still come with the flexibility, community and support services of a shared building.
Four expansions in four years tell their own story
L’illa & Co. opened in March 2022 at around 1,000 square metres. It grew to 1,600 sqm later that same year, then to 3,100 sqm across two floors by 2024. The new managed office floor takes the total to 4,500 sqm across three floors, more than four times its opening size, all at a single address.
That trajectory matters as much as the headline occupancy figure. Operators rarely expand a location four times in four years unless underlying demand keeps outrunning supply. In this case, the site’s landlord and its flex operator apparently agreed it was worth testing something different on the newest floor: instead of more open desks and shared meeting rooms, private offices built and branded for a single tenant.
The concept itself isn’t new. Managed offices, sometimes called “customised” or “serviced” offices, have existed alongside traditional coworking for years. What’s notable here is the demand signal: an operator adding a dedicated managed office floor to an already mature site, and filling most of it before the paint has properly dried.
A landlord and a flex specialist, working as one team
L’illa & Co. is owned by Indicesa L’illa, the company behind the wider L’illa Diagonal complex, a mixed-use development combining more than 170 shops and restaurants, two four-star hotels, offices and public facilities, with tram, bus, metro and high-speed rail access all within about ten minutes on foot. The flex workspace concept itself is managed by Savills Flex, the flexible workspace division of international property advisory firm Savills, which has also handled the design of each of the site’s expansions to date.
That combination, a real estate owner with a landmark asset paired with a specialist flex operator running the day-to-day workspace product, is a structure that’s becoming increasingly common across Europe. Rather than treating flexible workspace as a side hustle, landlords are bringing in operators who understand occupier demand, pricing and community management, while keeping ownership of the underlying property. Savills Flex positions itself precisely in that space, working with property owners to build and run flexible offerings rather than owning buildings itself.
Private space without losing the flexibility
The appeal of a managed office is fairly simple to explain. A company that’s growing, or unsure exactly how much space it will need in twelve months, doesn’t want the multi-year lease and capital outlay of a traditional office. But it also doesn’t always want its whole team working from an open coworking floor alongside a dozen other companies. A managed office splits the difference: a private, brandable space sized to the tenant, wrapped in the flexibility and shared infrastructure of a coworking operator, from meeting rooms and reception to IT and community events.
For landlords and operators, the economics are attractive too. Managed offices typically command higher revenue per square metre than open coworking desks, while still offering tenants shorter commitments than a conventional lease. It’s a formula that’s shown up repeatedly in recent European flex market data, with managed office space growing significantly faster than open coworking floor space in several major cities over the past few years.
L’illa & Co.’s Barcelona expansion is a useful, concrete illustration of that pattern in action: a single site, tracked over four years, showing the shift from shared desks to private, serviced space happening in real time, on a floor that filled up before the ink was dry on the lease.
The lesson for operators sitting on a mature site
For flex operators and landlords elsewhere in Europe, the takeaway isn’t necessarily “build a managed office floor tomorrow.” It’s that mature, high-occupancy coworking sites may have more room to grow than their operators assume, not by adding more shared desks, but by carving out a different product for tenants who’ve outgrown a hot desk but aren’t ready for a decade-long lease.
Barcelona’s Diagonal corridor is a well-established, high-demand business district, which no doubt helped the new floor fill quickly. But the underlying signal, occupiers wanting private space without giving up flexibility, is one that’s playing out well beyond Spain.
