A 45-storey Norman Foster tower in Canary Wharf, guarded by replicas of the Hong Kong head office's lion statues.
- 45 storeys at 8 Canada Square
- 18 weeks fully paid parental leave (primary caregivers)
- 85% of colleagues work hybrid
HSBC's global headquarters rose from “a soggy hole in the ground” in Canary Wharf from early 1999. Norman Foster, who had rebuilt HSBC's Hong Kong head office, designed a more streamlined tower; a Feng Shui Master was consulted, and replicas of the Hong Kong lion statues were cast to guard the entrance when it officially opened on 2 April 2003.

Unilever House from the river, 2014 · Arild Vågen / CC BY-SA 3.0 · Wikimedia Commons 03Unilever · London, United Kingdom
Behind a listed 1932 stone facade on the Thames, KPF carved a light-filled atrium crossed by suspended bridges, with a roof garden on top.
- 392,400 sq ft Unilever House after KPF's renovation
- 1932 Unilever House opened on the Embankment
- 59,000+ employees reached by Healthier U
KPF kept and restored the Grade II listed stone exterior and completely reconfigured the inside. A new central atrium brings air and daylight into the middle of the building, crossed by suspended bridges and platforms that double as informal meeting spaces. The roof plant was moved to make way for a roof garden for work and breaks, with views to St Paul's Cathedral, and the original Embankment entrance was reopened.

One Churchill Place on the skyline · Photo: HOK 04Barclays · London, United Kingdom
A 1 million sq ft Canary Wharf tower with five six-storey glass atria stacked up its south face — and, from 2026, 16 weeks of full-pay leave for new fathers in the UK.
- 1M sq ft One Churchill Place, HQ since 2005
- 16 weeks full-pay paternity leave (UK, from 2026)
- 5,000 staff moved in from 14 London buildings
HOK pushed the service cores to the north side so that a bank of five atria, each six storeys high, could rise up the south facade. Each atrium has its own visual theme, with planting and commissioned artwork, and serves as space for meetings or a break. Barclays' archive describes open steel-framed floors meant to get people talking, glass that brings daylight deep inside, a gym, a multi-faith prayer room and a roof garden.

A 27-storey 1960s tower on London's South Bank, refitted floor by floor — with an onsite gym and 30 days of annual leave.
- 27 storeys in the Shell Centre tower
- 26 weeks maternity or adoption leave on full pay (UK)
- 30 days annual leave in the UK, plus buy/sell up to 5

A Soho headquarters built around Diageo's brands, with a bar, a restaurant and a shop open to the public.
- 900 London staff brought under one roof
- 26 weeks fully paid maternity leave, worldwide minimum
- 88% of employees proud to work at Diageo (2026)
Diageo pre-let the whole building in 2019 and the developer reworked the existing structure, widening the floor plates instead of rebuilding. Interior designer MCM set out to make a place where “workspace, brand, hospitality and experiences” meet: there is an immersive customer collaboration centre, bar and entertaining spaces, a commercial kitchen and restaurant, and a Diageo shop open to the public. Diageo said its employees would help design their own workspace.

YY London, 30 South Colonnade · © Revolut 09Revolut · London, United Kingdom
Four floors of a Canary Wharf tower with a gym, a sauna and an auditorium — for a company that lets its people work abroad for up to 120 days.
- 113,000 sq ft over 4 floors (≈ 10,498 m²)
- 120 days a year of work from abroad
- 13,000+ people worldwide (2026)
Revolut took four floors of YY London, the refurbished 30 South Colonnade. The interiors were designed and built by AIS in 10 months on site and more than 180,000 build hours. Revolut asked for an office people want to come into, not one they have to: AIS added a gym, a sauna, an auditorium and large LED walls. As a remote-first company, Revolut uses the space for product launches, workshops, team events and collaboration.

Greater London House, Hampstead Road · © spacelab_ 10ASOS · London, United Kingdom
ASOS works from a former Art Deco cigarette factory in Camden, where two open courtyards were filled in to make a three-storey “central street”.
- 190,000 → 250,000 sq ft occupied after the refit
- 2,500+ people the HQ was planned for
- 3pm Friday finish in June–August
ASOS's head office is Greater London House on Hampstead Road in Camden. ASOS describes it as a former cigarette factory, an Art Deco building now renovated with open office areas, the ASOS Studios where it shoots its products, beauty rooms, a free gym, and a subsidised canteen and café. Designer Spacelab enclosed the building's two external voids — it had been shaped like a figure of eight — to add three storeys of floor space and a “central street” of meeting rooms, a tech bar, lounges, a restaurant, coffee shops and an amphitheatre with a large digital screen. The lower ground floor is the ASOS Academy, with a gym, fitness studios, beauty rooms and rooms for prayer and meditation. Original Art Deco railings inspired the new balustrades, and the Crittall windows were largely kept.

A gutted government building in Westminster, now two glass-roofed atriums crossed by black metal bridges — Burberry's whole London team under one roof.
- 150,000 sq ft Horseferry House (≈ 13,935 m²)
- 18 weeks paid parental leave for every parent
- 5+ days paid wellbeing leave a year
Architects AHMM gutted a seven-storey island-site building and opened its lower floors to the street with double-height entrances. A forgotten courtyard and a lightwell became two full-height atriums under ETFE pillows, crossed by black metal bridges that double as breakout spaces. On the seventh floor, glass “pop-ups” lead to roof terraces. Gensler designed the interiors — design and photo studios, showrooms and offices that brought five London offices together.
