17 Hertford Street · archival image
A proposal from Attaché Global
An invitation to explore a Fendi Café and Managed Apartments by Fendi in the heart of Mayfair.
The opportunity
One address. Two complementary expressions of the house: a public ritual at street level and a private residential experience above.
Fendi Café · concept campaign
Six perspectives on how Fendi’s design identity could extend into hospitality at 17 Hertford Street.
A street-level expression shaped by light, material and service.
The proposed experience
The café introduces the house through hospitality. The apartments extend that relationship through residence, service and long-term care.
Spatial study
The drawing explores a possible street-level café arrangement and the relationship between seating, service, circulation and access.
A coherent residential experience could unite curated interiors with professional management, planned maintenance and discreet resident support.
Managed Apartments · spatial studies
Four supplied architectural studies paired with proposed interior atmospheres. Drag each gold handle across the drawing.
Spatial Study 01

Arrival & interior finishes
The proposed residential entrance separates private arrival from the café. The bathroom illustrates a possible approach to stone, timber, metalwork and lighting.
The CGIs suggest a design direction only. They do not confirm the final layout, dimensions, finishes or furniture specification. Furniture is illustrative except where the Peekasleep bed and Cleo armchair are identified. Any visible Fendi or FENDI CASA lettering is conceptual branding—not a verified retail product or approved brand application.
A shared material language
A controlled palette could connect the two experiences without compromising their different roles: social and visible below; calm and private above.
Concept visualisation · not an approved specificationMarket context
Mayfair’s draw is a mix of hotels, clubs, galleries, restaurants and two royal parks. Residents, hotel guests, local professionals and visitors give the streets a rhythm that changes by hour and by season.
The figures below are published measures, each labelled for what it actually counts. Station and national statistics describe the wider area and the country—not pedestrian volumes outside the building. No footfall count exists for Hertford Street itself, so none is given.
Annualised entries and exits, 2024. A station count, not a pedestrian count.

The Royal Parks / Statista, 2014 surveySeasonality
Both charts show published London and UK demand patterns as a relative index. They are context for planning rhythm and staffing thinking—not predicted covers, bookings or revenue.
For comparison, a sample of branded full-service central London hotels recorded 2025 occupancy peaking in July at 92.7% and reaching its lowest point in January at 66.5%, with full-year occupancy of 84% (Cushman & Wakefield, London Market Spotlight FY 2025).
Published price bands
Ranges taken from published Mayfair menus and advertised apartment rates. They describe the market a café and managed apartments would sit within.
Published market context only. Nothing here is a forecast, projection, guarantee or proposed tariff. Any pricing would follow design, service specification, operating model and commercial agreement.
The commercial centrepiece
“By renting, we can control the brand better.”
Consistent interiors, planned replacement cycles, defined service standards and a direct relationship with residents.
Personal fit-out choices, variable participation in services and slower intervention when standards slip.
Rental is an enabling structure, not a guarantee. Brand control depends on robust agreements, defined operating standards, active oversight and sustained investment.

Walking times are approximate and rounded from public pedestrian-route references. Station figures elsewhere remain station usage counts, not pavement footfall.
The Mayfair context
Established hotels and private clubs place the building within a mature luxury-hospitality setting—not a destination waiting to be invented.
Change, with status made clear
Reopened October 2025.
Currently taking bookings for 1 February 2027; delivery remains subject to change.
Consultation is not completion.
The building’s provenance
No. 17 was built around 1768 by Henry Holland the elder, with his son and John Eldridge. The younger Henry Holland lived here after his marriage in 1773.
The building later accommodated flats and a ground-floor restaurant. Its listing records a mid-twentieth-century restaurant frontage; supplied archive material connects the corner with Balsam’s Restaurant.
The invitation
Attaché Global invites Fendi to test the creative, operational and commercial potential together.
