   An R&D campus of 12 villages, each modeled on a famous European city — with 800 meeting rooms, 15 canteens and 10 coffee shops.

   • 12 European-style villages at Ox Horn

Huawei says the villages copy how European designers fit buildings into their natural surroundings, and are meant to help employees relax from the pressures of work. Back in Shenzhen, the Bantian headquarters has 11 specialized zones built in different styles, crowned by the F1 tower.

   Comcast · Philadelphia, Pennsylvania

   A 120-foot glass winter garden with a free 27-million-pixel video wall in the lobby — and a two-story staff cafeteria on the 43rd and 44th floors.

   • 58 stories in Comcast Center, the HQ
   • 1.25M sq ft headquarters tower (≈ 116,129 m²)
   • 16 weeks paid leave for primary caregivers

Comcast's floors end in a conference floor with the executive offices just below, and a two-story employee cafeteria sits on floors 43 and 44 above a training center. Next door, the Comcast Technology Center houses the company's technologists and engineers under a block-long glass lobby.

   Orange · Issy-les-Moulineaux, France

   Orange's first global headquarters is built around a planted atrium 32 metres high, on the banks of the Seine.

   • 56,000 m² Bridge HQ (≈ 603,000 sq ft)
   • 32 m high planted atrium
   • 3 days telework a week, at most

   Bridge faces the Île Saint-Germain at the Issy bridge. VIGUIER describes two buildings around a public pedestrian space: a new office building with a 15-metre glass cantilever, and a refurbished Eiffel-style covered market with coworking spaces, shops and restaurants open to the public. Inside, a landscaped atrium with suspended volumes runs the length of the building; office floors extend onto planted balconies and two levels of planted roofs, under three wide glass roofs. Wood, metal, stone and concrete were chosen for their raw look. Orange says the building has only eight floors to make the company more horizontal, with open spaces where people meet in more or less formal settings, from flex office to individual “bubbles”.

   Vodafone · Newbury, United Kingdom

   Seven buildings set round a lake, linked by bridges and tents — and when it opened, not even the CEO had an office of their own.

   • 30 acres campus in Newbury, opened 2003

Each building is two blocks around an atrium, with open stairs and bridges wide enough for informal work. Cafés, a lakeside restaurant, a fitness centre and a tensioned-fabric Pavilion for events complete the site.

   Ericsson · Stockholm, Sweden

   It began in a 13 m² workshop in 1876; today about 10,000 people work at the Kista headquarters — and from 2028 they start moving to a new city campus in Hagastaden.

The Ericsson Studio, first opened in 2010 and fully refreshed in 2020, is the campus showcase for customers, partners and events, and next to it a 1,250 m² blue “Imagine Possible” testbed is open to everyone.

    T-Mobile US · Bellevue, Washington

    A vintage Airstream serving frozen yogurt, a campus pub and a grand staircase that doubles as an amphitheater — inside T-Mobile's renovated Bellevue headquarters.

    • 40,000 sq ft amenity centerpiece at the HQ

    SoftBank Group · Tokyo, Japan

    A 40-storey smart tower on Tokyo Bay where employees choose their own seat each day — and the lunch salad is grown on the tower's own terraces.

Terraces on floors 2–6 hold “Takeshiba Shin-Hakkei”, eight small landscapes including bees, a rice paddy and a vegetable garden whose produce is served in the cafeteria.

    Telenor · Fornebu, Norway

    Telenor built its headquarters on Norway's former national airport, bringing about 6,000 people from 40 Oslo addresses under one roof — with kayaks in the basement and a private jetty on the fjord.

    • 40 → 1 Oslo addresses brought under one roof

    Telenor's headquarters stands on the site of Norway's former national airport at Fornebu, along the eastern shoreline. The winning design, “Uffizi Nuovi”, was unveiled in 1997. Offices are arranged in units of about forty people, floor plates are never more than 16 metres wide so daylight reaches almost every corner, and atriums link the floors to the boulevards and an open-air central plaza. Inside today: three canteens, the Expo Café furnished like a hotel lounge with fjord views, The HUB — a small house in the middle of the plaza with a coffee bar for all-hands meetings — and “heart zones” with coffee, fruit and chocolate drawers.
