Office-led proposals will add new storeys to Fenwick building and boost floorspace by almost 40%

Foster & Partners has drawn up proposals to radically refurbish the Mayfair branch of the Fenwick department store, adding five new upper floors and roof terraces to the buildings, the centrepiece of which is 136 years old.

The practice鈥檚 plans, which have been submitted to Westminster City Council, aim to 鈥渞ejuvenate the site鈥 at the junction of Brook Street and New Bond Street when the department store closes next year.

Fosters鈥 scheme includes the demolition of some elements of the buildings 鈥 and a neighbouring unit in New Bond Street, with fa莽ades being significantly raised.

Foster & Partners鈥 proposals for the Fenwick department store in Mayfair

The practice described the project as a 鈥渄eep retrofit鈥 designed to offer 鈥渨orld-class retail accommodation that is futureproof鈥 at ground- and first-floor level with 鈥渂est in class鈥 office accommodation on the floors above.

Property firm Lazari Investments bought the Fenwick buildings last year for a price reportedly in excess of 拢400m. They are not listed but the whole development site sits within the Mayfair Conservation Area.

Fosters鈥 plans for the company would deliver a 38% increase in floorspace at the site. The current buildings have 12,292 sq m of retail space and 2,287 sq m of office space.

Under the proposals, the amount of retail space would drop to 4,692 sq m but there would be a significant increase in office accommodation, to 16,262sq m.

The new retail offer would be limited to four units accessed from New Bond Street. The scheme鈥檚 offices would be accessed from Brook Street.

Fosters鈥 proposals would see the existing building鈥檚 fa莽ades raised by a storey to keep the structure鈥檚 current appearance but deliver modern-specification store fronts.

How the existing store currently looks

The practice said its design celebrated the 鈥渄iverse architectural heritage鈥 of the historic plots that had been brought together to make the current store over multiple decades 鈥減resenting distinct ground and first-floor facades for each tenant鈥.

The office element of the design contains an atrium that would be lit from the fifth and sixth floors of the building鈥檚 western side, with amenity terraces for tenants on each floor. Fosters said the terraces could be connected with internal stairs if a single tenant took the space.

In addition to Fosters, Lazari Investments鈥 project team includes project manager Gardiner & Theobald, structural and fa莽ade consultant Buro Happold, MEP consultant Cundall, planning consultant Gerald Eve and landscape architect Townshend.
